Why and when should you replace your fatbike battery?
A fatbike battery replacement is a job you will encounter sooner or later if you have an electric fatbike. This is because the battery is the beating heart of your bike and thus determines how many miles you can cover. So when you notice that your range decreases or the support becomes less, it is often time to take action. In this blog you will read exactly when replacement is necessary, how to choose the right battery and how to install it yourself.
At STOER Bikes because we understand how important a reliable battery is for your daily rides. So our fatbikes come standard with a powerful 720Wh battery with a range of 80-100 kilometers. Still, even the best battery comes to the end of its life at some point. That's why we are happy to help you with all the information you need.
How do you recognize that your fatbike battery needs replacement?
So your fatbike battery often gives clear signals when replacement is needed. In fact, the most important sign is a decrease in your range. So, if you used to get 80 kilometers and now only get 40 kilometers, that is a clear signal. This is because the cells in your battery have weakened and can therefore store less energy.
Declining range as first signal
So a healthy fatbike battery will last an average of 3 to 5 years with normal use. In fact, this equates to about 500 to 1000 charging cycles. A charging cycle is in fact the complete charging and discharging of your battery. So if you use half of your battery and recharge it every day, this counts as half a cycle. So your battery wears out gradually with each use.
The STOER UrbanX and CityX thus both have a 720Wh 48V battery. In fact, this battery offers a range of 80-100 kilometers, depending on your riding style and support level. So when your range drops below 50 kilometers while riding the same way, this is often a sign that the battery is underperforming. You should then think about replacement.
Longer charging times indicate problems
In fact, another clear signal is that your battery takes longer to charge. So the charging time of a STOER UrbanX or CityX battery is normally 6-8 hours. So if this suddenly takes 10 hours or longer, then the cells are no longer functioning optimally. In fact, this indicates internal resistance in the battery which thus increases with aging.
So also pay attention to the behavior while riding. So does the support sometimes drop off when accelerating or climbing? Then the battery may not be supplying enough power. This is especially noticeable on the STOER CargoX with heavy loads, as the 92Nm motor then demands a lot of power from the 960Wh battery. So you notice this especially at hills.
Physical changes to the battery
So check your battery regularly for physical changes. This is because swelling of the casing is an alarm signal that thus requires immediate action. In fact, a swollen battery can be dangerous and thus you should no longer use it. Corrosion at the connections or cracks in the casing are also reasons to replace the battery. So pay close attention to this.
"In fact, the battery is the most expensive part of your electric fatbike," explains Joeri of STOER Bikes. "But if you maintain it properly, therefore, it will last for years. So pay special attention to the storage temperature and never charge it completely empty."
Which fatbike battery fits your model?
So choosing the right replacement battery is very important. This is because you need to pay attention to the voltage, the capacity and also the physical dimensions. This is because the wrong battery can damage your bike or even be dangerous. So always choose carefully.
Checking voltage and capacity
So the voltage of your battery must match your system exactly. STOER fatbikes work on 48V, in fact, so you need a 48V battery. A 36V battery will not work on a 48V system, and the other way around can cause damage. So always check the voltage on the label of your current battery. This is very important.
The capacity is thus expressed in watt-hours (Wh) and thus determines your range. In fact, the STOER UrbanX and CityX have a 720Wh battery, while the CargoX thus has a larger 960Wh battery. So you can often choose a battery with the same or higher capacity, provided the physical dimensions thus fit. After all, a higher capacity means more mileage, but therefore also more weight.
Physical dimensions and connections
So measure the length, width and height of your current battery before buying a new one. This is because the battery must fit exactly into the mounting bracket of your fatbike. Also pay attention to the type of connector, because different brands use different connections. Check this in advance.
Therefore, only STOER batteries fit STOER fatbikes. The original STOER charger is in fact specially tuned to these batteries for optimal charging performance. So we recommend always using original parts for best results and also safety.
Where do you buy a replacement battery?
So buy your replacement battery from a reliable supplier or directly from the manufacturer. This is because the e-bike battery market has many cheap alternatives of varying quality. In fact, a battery from an unknown brand may not last as long or may even be unsafe. So choose wisely.
At STORE dealers So you can get original replacement batteries with full warranty. In fact, you will also get advice here on the right choice for your specific model and use. This is especially important if you travel a lot or use your fatbike for business. You are then assured of quality.
How to safely remove the old fatbike battery?
So removing your old battery requires caution. This is because lithium-ion batteries are powerful components that can therefore be dangerous if mishandled. So follow these steps for safe disposal. You will avoid problems by doing so.
Preparation and safety
So put your fatbike down stably on a flat surface or in a mounting stand. So turn off the bike completely and also remove the key from the system. So check that all electronic systems are turned off, because there should be no lights on the display. So this is the first step.
So wear gloves to protect your hands from sharp edges and also possible corrosion. So also make sure you have adequate lighting in your workspace. After all, you are working with electrical components that you therefore need to be able to see well. So take your time for this.
Disconnecting the battery step by step
So look for the locking or mounting bracket of your battery. This is because on most STOER fatbikes the battery is in the frame and you can unlock it with the key. In fact, the batteries of the UrbanX and CityX are removable, so this makes replacement easier. So this is convenient.
So first unlock the battery with the key provided. This is because some models also have clamps or screws that you therefore need to loosen. Next, carefully lift the battery out of its mount. Be careful not to disconnect the connector yet. So work calmly and in a controlled manner.
So after that, carefully disconnect the main connector by pulling it straight out. So never force a connector by bending or twisting it, as this may damage the connector. So if the connector is stuck, check that all the latches are loose. Patience is important.
Safe storage of the old battery
So store the old battery in a dry, cool place away from flammable materials. This is because even a defective battery may still contain residual charge and thus pose a potential fire risk. So stick tape over the connections to prevent short circuits. This is, in fact, an important safety measure.
So return your old battery to an authorized collection point within 3 months. In fact, most bike stores take in old e-bike batteries for recycling free of charge. In fact, this is required by law and also good for the environment. So you are contributing to sustainability.
How do you install a new fatbike battery?
So installing your new battery starts with proper preparation. Namely, first fully charge the battery according to the manufacturer's instructions. This is because this is important to correctly calibrate the battery management system thus. By doing so, you ensure optimal performance.
Preparing the new battery
So before installation, check that all connectors are clean and also dry. So if necessary, use contact spray to remove corrosion from the connection points in your fatbike. Compare the new battery again with the specifications of your system to be sure that voltage and capacity match. This will prevent problems.
So the first charge usually takes 6-8 hours for STOER's 720Wh batteries. So have the battery fully charged before you install it, as this will ensure the best performance from the first use. So you will then start with a full battery.
Inserting and connecting the battery
So carefully insert the new battery into the mounting bracket. So make sure that the battery falls properly into the guides. So then connect the main connector by pushing it straight in until you hear a click. Never force a connection as this may damage the connector. Work carefully.
So check that the connector is completely tight and also has no play. So then lock the battery with the key and also check that all the attachment points are tight. So gently shake the battery to test if it is thus firmly attached. This, in fact, gives assurance.
Testing the installation
So turn on your fatbike and also check that the display starts up normally. This is because the display must show the correct battery status and all functions must therefore work. So if the display does not recognize the battery, turn off the bike and check all connections again. This often solves the problem.
So perform a short test ride in a safe environment. So test the different assistance levels and also pay attention to any unusual noises or vibrations. The STOER UrbanX This is because it has 5 levels of support, all of which should therefore work smoothly. So you will notice immediately if everything is working properly.
So after the first test drive, it is wise to check all connections again. So also recharge the battery fully again, as this in fact helps the battery management system to make accurate capacity measurements. You thus ensure optimal usage by doing so.
Tips to extend the life of your new battery
So with proper care, your new fatbike battery will last for years. So here are the most important tips to maximize its lifespan. So follow these tips carefully.
Correct charging for longer life
So, preferably charge your battery between 20% and 80% capacity. This is because lithium-ion batteries have no memory effect and therefore do not need to be completely empty before charging. In fact, leaving them completely empty is actually harmful to the cells. So always avoid this.
So always use the original charger that comes with your fatbike. This is because the STOER charger is specially tailored to the 720Wh and 960Wh batteries for optimal charging performance and also safety. This is because a cheap charger can damage the battery or charge it too slowly. So invest in quality.
Temperature and storage
So store your battery in a cool, dry place at room temperature (15-20°C). Extreme temperatures, both cold and hot, actually shorten the life of the cells. So do not leave your fatbike in the full sun for hours. This is because it is harmful to the battery.
So take the battery inside when your bike is outside for long periods of time. This is because the removable batteries of STOER fatbikes are specially designed for this purpose. So you protect the battery from temperature fluctuations and also theft at the same time. This is a double advantage.
So never store your battery completely empty for long periods of time. This is because a battery with too little charge can discharge deeply, thus preventing it from charging. So store the battery with 50-60% charge and also check the charge level monthly. This, in fact, prevents problems.
Maintenance while cycling
So make sure your tires are properly inflated, because tires that are too soft increase rolling resistance. This in fact causes your battery to have to work harder and thus drain faster. The thick tires of STOER fatbikes have an optimal pressure of 1-2 bar, depending on the terrain. Check this regularly.
So start your ride without immediately turning on the support. Driving off with active support requires a relatively large amount of energy from the battery. So by getting going yourself first, you save power and thus extend the life of the battery. This is, in fact, a simple tip.
What does it cost to replace a fatbike battery?
So the cost of a new fatbike battery ranges from €300 to €800, depending on capacity and brand. So a high-quality battery from a reliable brand is often more expensive, but in fact it also lasts longer. So invest in quality.
Investment in quality
So an original replacement battery for your STOER fatbike is an investment that pays for itself. After all, you get the assurance of quality, safety and also warranty. Cheap alternatives may seem attractive in the short term, but often do not last as long. So think long term.
So when you buy a new STOER fatbike, you get a 2-year warranty on the battery and motor. This warranty also applies to original replacement batteries purchased from a STOER dealer. This gives you security for years to come. You are thus well protected.
Revision as an alternative
In fact, some companies offer battery overhaul as a cheaper alternative to replacement. Revision, then, involves replacing the worn-out cells with new ones, thus making the battery functional again. In fact, this is often 30-50% cheaper than a new battery. So consider this option.
Please note that there are thus no standards yet for the quality of remanufactured batteries. A new original battery goes through extensive safety tests that remanufactured batteries do not always undergo. So weigh the costs against the risks. Choose wisely.
Professional help replacing your fatbike battery
So do you doubt whether you can replace the battery yourself? Then you can go to a professional bike shop or STOER dealer. They have the right tools and knowledge to do the job safely. You are in good hands.
At STORE dealers so you can also have a diagnostic done before buying a new battery. This is because sometimes the problem is not with the battery, but with the charger or electronics. So a professional diagnosis prevents unnecessary expenses. In fact, this is a smart thing to do.
So do you want to experience for yourself how our fatbikes ride? Then plan a test ride at a dealer near you. So you can then also get immediate advice on maintenance and also replacement parts. In fact, this is the best way to choose.
Frequently asked questions about fatbike battery replacement
How long does it take to fully charge a new fatbike battery?
So a new fatbike battery usually needs 4-8 hours for the first full charge, depending on its capacity. Indeed, the STOER 720Wh battery charges in 6-8 hours, while the larger 960Wh CargoX battery thus requires 4-6 hours. So always have the battery fully charged before the first use in order to correctly calibrate the battery management system thus.
Can I use a higher capacity battery than my original one?
So yes, you can usually use a higher-capacity battery as long as the voltage thus remains the same and the physical dimensions thus fit. A higher capacity means more riding distance, but also more weight. Make sure your bike frame and mounting system can handle the extra weight. Only original STOER batteries fit STOER fatbikes.
What should I do if my new battery is not recognized?
So first switch the bike completely off and on again. So also check that all connectors are tight and also clean. So if the problem persists, the battery management system may actually need a reset. So this often happens automatically after a few charge and discharge cycles. So contact the supplier if the display still does not show correct information after 2-3 cycles.
How do I safely store my old battery until recycling?
So store the old battery in a dry, cool place (15-20°C) with about 30-50% charge. So stick tape over the connections to prevent short circuits, and so store the battery away from flammable materials. So return the battery to an authorized collection point within 3 months. In fact, most bike stores and STOER dealers take in old e-bike batteries free of charge.
What tools do I need for replacement?
So for most STOER fatbikes, you only need the included wrench to unlock the battery. In fact, sometimes a Phillips screwdriver and Allen wrenches (usually 4mm or 5mm) are thus needed for additional fixings. So always wear gloves for your own safety. In fact, a multimeter is useful for checking voltage, but not strictly necessary.
How do I maximize the life of my new battery?
So charge the battery regularly before it is completely drained. So preferably keep the charge between 20-80% capacity. So store the battery at room temperature and so avoid extreme cold or heat. So use the battery at least once a month to avoid deep discharge. So in long-term storage, keep the battery with 50-60% charge and so also check the charge level monthly.
