1 minute judgment: Is it time to replace your electric bikes battery?

  Recently, many users have reported and asked: "How long can an electric bikes battery last?"

The battery can be said to be the heart battery of an electric bikes. Its performance status will directly affect the overall condition of the electric bikes. In serious cases, it may cause a fire. Many electric bikes users know little about batteries.

  How to tell if the battery needs to be replaced?

  Generally speaking, the battery can be used for 1 to 2 years. The service life of the battery with a larger discharge depth is about 1 year. The service life of the electric bikes battery with a discharge depth of 50% to 70% is about 2 years.

When the use time of the electric vehicle battery far exceeds the normal use time, it will seriously affect the normal performance of the electric vehicle. Remember to replace it in time.

"How to tell if the battery needs to be replaced?"

  ①The battery is full as soon as it is charged and runs out of power as soon as it is used.

   Usually it takes about 8 hours to fully charge. If the time required to fully charge is getting shorter and shorter, and the battery runs out after being unable to run much distance, it may be caused by the following two reasons:

  [Partial Failure] First, a small battery in the battery pack has failed, and the small battery itself is difficult to repair, so the entire battery pack can only be scrapped;

  [Overall aging] The second is that the battery capacity has shrunk and the power storage function has almost been lost, so the electric vehicle battery is basically scrapped.

  ② Performance drops sharply after being used for more than 3 years

   The capacity attenuation of the battery is irreversible. All components of the battery that have been used for more than 3 years have basically reached the level of deterioration, and this deterioration will gradually accelerate, and soon the battery will completely lose its charge and discharge capabilities. If the battery is still unable to save after repair power, indicating that the battery has been scrapped.

  ③ Charging heats up and the battery bulges.

   When the battery heats up when charging, the main reason is that the active material on the plate is seriously peeled off, the internal resistance increases, and the heat generation increases. Batteries self-discharge very quickly and even run out of power quickly after being charged. In severe cases, the battery will bulge, and the battery casing and circuits may even burn, which is very dangerous.

  ④ Battery capacity is less than 60% of normal capacity

   When the battery is used normally, its capacity will gradually decrease. Taking 48/12 as an example, the 40-kilometer battery life of a new battery is relatively normal. Once it is fully charged, it cannot run 20 kilometers, indicating that problems have begun to occur in various components of the battery, and various performance improvements have occurred. decline, the performance is extremely unstable, and may cause adverse consequences such as heating and deformation during charging.

  When the battery has the above 4 conditions
