Considering that your e-bike battery is one of the most expensive and important components of your bike, we thought we would share some tips that every e-bike owner should be aware of to keep your e-bike battery in the best condition, and to prevent expensive repairs and replacements. So here are a few guidelines if you want your e-bike battery to realize its optimum lifespan.
- Before attempting to charge your e-bike battery for the first time, read the owner’s manual and check your bike’s warning stickers. Manufacturer’s instructions are certainly helpful for first time owners, since they typically provide important information including safety and maintenance instructions and warnings. Always be aware of all safety precautions that should be observed while charging. If you do not understand clearly the instructions or guidelines on your manual, you should get in touch with your ebike dealer.
- When storing and charging your e-bike battery, always avoid extreme weather conditions to prolong its life. Keep it cool all the time, but not extremely cool. It is more advisable to charge your bike in a well-ventilated, open location to prevent it from overheating. Avoid storing it in a garage or any place that have direct sunlight. In addition, warm up the bike battery to room temperature before charging it, since charging from a very cool environment can also damage it. The recommended storage temperatures for your battery are 32°F – 77°F. Also, avoid exposing it to extreme heat temperature 104°F+ for long periods of time. Expect your e-bike battery to show signs of aging sooner if you frequently expose it to extreme cold or extreme heat conditions. Moreover, keep open flames and sparks away from your battery. In case your bike battery got frozen, do not attempt to charge it. Do not use the charger in locations where it may be exposed to rain or moisture to prevent electrical shock.
- It is advised that you do not leave your battery completely drained or depleted, since it causes irreparable damage to the cells. To get the longest life out of your e-bike battery, keep them charged at all times. Discharging the battery regularly decreases its capacity to hold a charge, thus weakening its ability of the battery to power the bike. If you're riding regularly or even having short rides, give it a full charge as often as possible. Moreover, it is recommended that after having long rides it is best to wait approximately 30 minutes to allow your bike batteries cool down before recharging. Never ever store the bike battery with an empty or low charge for more than a few hours. Also avoid quick charging as this only charges the surface and can increase the risk of overheating, leading to permanent battery damage. Never leave it partially discharged since it can cause internal oxidation. Overcharging and undercharging your battery will have a bearing on battery lifespan. Overcharging may cause excessive gassing (water breakdown), heat buildup, and battery aging, while undercharging may cause stratification which can lead to premature battery failure. Also, never use a different charger, it is considered dangerous and can cause explosion. It is advised to only use the charger that supplied with your e-bike.
- Always inspect and ensure your battery is dry and clean, free from dirt and grime. We all know for a fact that water and humidity is not really good for all electronic devices. Also, dirty battery can discharge across the grime. To prevent cases of oxidation and corrosion, contacts should be dried. Check the contacts on the battery once a month and clean if necessary. Moreover, emery cloth can be used for cleaning if there are any corrosion found. Also, keep your battery's contacts away from metallic objects to prevent an electrical short.
- Remember to make a plan for long-term storage of the e-bike. Flattening a battery is not recommended. It is advised that your bike battery should be stored in a cold place, monitored, and given short charges at least every 3 months. If batteries were not recharged regularly, they will internally oxidize thus causing a shortened battery lifespan and a lower mileage range.
- Examine and inspect your battery regularly for leakage. Any fluids on or around the battery may indicate spilling or leaching. Leaking batteries must be repaired or replaced. Also, never open, examine and exposed your bike battery. Never try to repair its contents. Exposing yourself to an opened bike battery is very hazardous. It is not safe since the bike battery powder is tremendously flammable and will combust on oxygen contact, thus making the bike battery cause an explosion. Find a reliable electrician or return it directly to your e-bike dealer if you suspect a defective bike battery for further check-up, testing and repair.
- Always use the same brand when replacing your e-bike batteries. Mixing and using different battery brands on your bike can cause internal oxidation of the batteries and lower the battery pack’s lifespan. In addition, ensure your new battery is properly tested before replacing your old or damaged one.
- Handle your battery with care by not dropping it. Dropping your battery may damage the cells. In case your battery was dropped and you find some signs that your battery is damaged, immediately stop using it unless the e-bike dealer has checked and declared it safe to use.
- For used or old e-bike batteries, do not throw them directly into the trash bin. Recycling these batteries is suggested since they can still be used. If you can find recycling centers or auto parts stores that accepts used batteries, drop them off for proper disposal.
These basic and easy guidelines are key to let you enjoy many trouble-free rides with your e-bike. Also, the simple recommended tips above can immensely extend your battery’s life. Happy riding!
