Electric bike batteries, like anything else you buy, need to be replaced from time to time. Unfortunately, there is no real way to predict when your electric bike’s battery will run down completely. This unpredictability is what makes electric bike batteries a particularly popular product among those that want an environmentally friendly mode of transportation. When looking for a replacement or backup battery for your electric bike, there are a few things you should keep in mind.
First off, you need to know exactly how many cycles your current battery is capable of producing before it begins to show signs of failure. Obviously, most electric bikes have a limited number of maximum cycles. This number, called a battery’s capacity, is usually indicated on the electric bike’s box or sticker. To get the most out of your electric bikes cycles, you should generally top off the number of maximum cycles before replacing the battery. On some models, the maximum number of cycles displayed may be different for different manufacturers. You should always check this number and replace your battery before it gets too low.
You also need to consider the voltage of the battery. The higher the voltage of the electric bike battery, the more amperes it can produce before it starts to show degradation. To find the ideal voltage for your electric bike battery, you should measure the current with a continuity tester at the end of one full cycle. Your amperes rating should be in accordance with the voltage of the battery you are considering. An ideal voltage is about four volts, which is the same as the voltage of your vehicle’s battery.
