Many people are confused about the life of electric bicycle batteries. How long can a set of electric bike batteries last? Why do some people’s batteries last for 2-3 years, while others’ batteries are scrapped after less than a year? How long is the life of an electric bike battery? 

When purchasing ebike batteries, many businesses will say that their own electric bicycle batteries will last for two or three years without any problems. However, in practice, it is found that many users’ electric bike batteries do not last that long at all. It needs to be replaced every year and a half. Is the battery quality bad? Or is it due to other reasons?

How long is the battery life?

There are generally two types of electric bicycle batteries on the market: lead-acid batteries and lithium batteries.
The life of a lead-acid battery is defined as the battery capacity decaying to 30% of the original capacity. Generally speaking, it should be fully charged and discharged about 300 times. The lifespan is about one and a half years. If the riding distance is short, it can be used for about 3 years;

Today's electric bicycles all use lithium batteries, and lithium batteries have strict charging times, generally around 1000-1200 times, and a lifespan of 3-5 years. However, the charging of lithium batteries is completely opposite to that of lead-acid batteries. They need to be recharged after they are used up. When the battery is not used for a long time, it needs to be fully charged every two months to prevent battery protection and extend battery life.

Why do battery lifespans vary?

Since the battery life is about 2-3 years, why do most people use it for more than a year or even half a year before it is scrapped? This is because many people do not pay attention to battery maintenance when using electric bikes. Neglecting battery maintenance may cause the electric bike battery to be damaged within the three-warranty period (lead-acid batteries are generally 12 months).

How to extend battery life?

To extend battery life, remember the following 2 points:

• Do not do anything that harms the battery

There are many behaviors that can damage electric bike batteries, such as over-discharging, sudden braking, excessive load, using new and old batteries in series, fast charging, overcharging, etc. These will affect the service life of the battery and shorten its service life.

• Regular maintenance

Regularly check the casing of the electric bicycle battery to see if there is any deformation, damage, scratches or other problems. If so, go to the maintenance point for repair in time and conduct a thorough inspection. If corrosion is found at the terminals, It must be dealt with promptly to avoid leakage of electricity.

Samebike electric bicycle batteries have a maintenance period of 1-3 years, providing basic protection for electric bicycles and ensuring the usability of electric bicycles.

Samebike—How should electric bike batteries be maintained?

Many times, electric bicycle owners do not know how to maintain electric bicycle batteries, which causes the ebike batteries to age too quickly. So, how to maintain electric bike batteries?

1. Time control

When purchasing a new battery, fully charge it before use for the first time. The first three charging times should be no less than 10 hours and no more than 12 hours each time, and each subsequent charging time should be 6-10 hours. In addition, the charging time is controlled according to seasonal changes. Spring and autumn: 7-8 hours; summer: 6-7 hours; winter: 8-10 hours

2. Charge on time

Every time you use it, please do not use the battery power to the minimum. You can charge it when the remaining power is about 25%. Develop the habit of charging in time to keep the battery power as full as possible.

3. Charging process

When charging, plug in the battery first and then plug in the power supply. After it is full, cut off the power supply first and then unplug the battery.

4. Cooling and charging

Do not charge immediately after each long-distance driving. Wait for the battery to cool down for 10 to 30 minutes before charging. This can extend the battery life.

5. Prevent power loss

When the electric vehicle is not used for a long time, the battery should be charged normally once a month, and long-term storage of "depleted battery" is strictly prohibited. Like when storing Samebike batteries for short or long term, charge the battery to the range of 75%-80%. And check once a month to make sure the battery percentage is no less than 75%.

6. Original accessories

Do not replace the charger casually, try to use the original charger, and do not remove the speed limit of the controller, otherwise it will reduce the service life of the battery.SAMEBIKE's battery chargers correspond to the battery voltage and capacity of each different electric bicycle.

7. Regular testing

When the battery capacity declines, you should go to the service station for inspection to determine whether the battery decline is normal. If necessary, the battery working condition can be improved through maintenance.

No matter what brand of electric bike you buy, it is recommended that you pay attention to the maintenance of the battery and do not let the battery be damaged due to temporary ease. Pay more attention to the maintenance of your ebike battery, so that the battery will be more durable and have long-lasting power!
