The Truth about EV Battery Life and Charging Best Practices

The Truth about EV Battery Life and Charging Best Practices

Ensuring the longevity of ebike batteries is a primary concern for many riders. Despite persistent myths regarding their lifespan, grasping the facts can help you optimise your battery's performance. In this article, we'll debunk prevalent misconceptions and offer practical tips for extending the life of your ebike battery.

Myth #01: Batteries Only Last 2 to 3 Years

Many associate short battery life with experiences from car or smartphone batteries. However, modern lithium-based ebike batteries can last far longer with proper care. Purchase a high-quality battery, store it in a moderate environment, and use it regularly to maintain its health. Avoid rapid charging and discharging, ensuring your battery serves you well for 5+ years. We have seen ebike batteries last over 50,000 km and more than 5 years without reduced voltage at full charge. The primary reason for premature battery failure we see is a lack of use e.g. the battery sits around unused/uncharged for two winters in a row. The other common reasons include storing the battery outdoors and using aftermarket fast chargers on a regular basis.

So why don't smart phone or car batteries last this long? Typically because users demand a lot of energy from them and then buy rapid chargers to top them up throughout the day. Batteries benefit and last much longer when depleting their energy at a regular rate and then charging them at a slower (standard) rate. 

Myth #02: Batteries Can't Be Recycled

Contrary to belief, electric vehicle batteries, including ebike batteries, can be recycled. Companies specialise in recycling and reconditioning batteries. Most ebike battery failures result from winter inactivity, causing internal cells to become unbalanced. Regular use and proper care can prevent these issues.

Myth #03: Using Rapid Chargers Will Damage the Battery

While fast chargers are designed to be safe, their frequent use can impact battery longevity. Opting for standard chargers is recommended for extended battery life. Think of it like driving a car – constant stress on the engine reduces its lifespan. Similarly, regular fast charging may affect your battery over time.

Myth #04: Keeping Your Battery Voltage Between 20% to 80% Charged

While maintaining your battery between 20% and 80% can enhance its life, it's often impractical for daily use. Most users prefer the convenience of a full charge. Despite the potential for a slight reduction in lifespan, the trade-off is minimal compared to the added weight, drag, and range anxiety associated with carrying only 80% of the battery capacity.

Myth #05: There Is a Lot of Maintenance for Older Electric Vehicles

Contrary to misconceptions, electric motors and components have been refined and proven over the years. For example, the electric motor predates the internal combustion engine and it is therefore well understood and refined. Direct drive ebike hub motors, in particular, have minimal moving parts and can last a long time with little maintenance. Modern electric vehicles benefit from well-understood technology adopted and carried across from traditional internal combustion engine vehicles.

Myth #06: People Who Don't Own an Electric Car Are Experts About Electric Cars

Misinformation often comes from those resistant to change and unfamiliar with electric vehicles. Experience and firsthand knowledge play a crucial role in understanding the nuances of electric vehicles, including ebikes.

Myth #07: The Electric Car or Bike Battery Is Going to Explode

Safety concerns around electric vehicle batteries are often exaggerated. Accidents related to battery explosions are more commonly linked to substandard chargers or self-built batteries. Following manufacturer guidelines and using reputable equipment minimises any potential risks.

Conclusion: Understanding the truths behind these myths empowers ebike enthusiasts to make informed decisions about battery care. By adopting proper charging habits and dispelling common misconceptions, you can enjoy longer rides and maximise the lifespan of your ebike battery.
