Battery Maintenance

The battery is one of the most important components of an electric bike. Eahora electric bikes are equipped with Samsung/LG Lithium 48V 14/12Ah batteries to ensure a long life expectancy and distinguished performance. The single range can be up to 60+ miles per charge on pedal-assist mode and around 35 miles on pure electric power mode. Moreover, Eahora offers a 1-year warranty on batteries.


If you know you won’t be using the battery for more than a few days, keep it charged at about 75% capacity. At 75%, the battery will degrade less than at higher charge levels.

Periodically check your battery's charge level once a month and charge it up to 75%.

Store the battery indoors in a dry space, away from heat or flame sources, and out of direct sunlight.

The typical estimated life of a Lithium-Ion battery is about two to three years or 300 to 500 charge cycles, whichever occurs first. One charge cycle is a period of use from fully charged, to fully discharged, and fully recharged again. Use a two to three-year life expectancy for batteries that do not run through complete charge cycles.

Rechargeable Lithium-Ion batteries have a limited life and will gradually lose their capacity to hold a charge. This loss of capacity (aging) is irreversible. As the battery loses capacity, the length of time it will power the product (run time) decreases.

Lithium-Ion batteries continue to slowly discharge (self-discharge) when not in use or while in storage. Routinely check the battery’s charge status. The product user manual typically includes information on how to check battery status, as well as battery charging instructions.

Observe and note the run time that a new fully-charged battery provides for powering your product. Use this new battery run time as a basis to compare run times for older batteries. The run time of your battery will vary depending on the product’s configuration and the applications that you run.

Routinely check the battery’s charge status.

Carefully monitor batteries that are approaching the end of their estimated life.

Consider replacing the battery with a new one if you note either of the following conditions:

  1. The battery run time drops below about 80% of the original run time.
  2. The battery charge time increases significantly.
  3. If a battery is stored or otherwise unused for an extended period, be sure to follow the storage instructions in this document. If you do not follow the instructions, and the battery has no charge remaining when you check it, consider it to be damaged. Do not attempt to recharge it or to use it. Replace it with a new battery.


Do not submerge the battery in a liquid of any kind.

Do not use any metal to touch the charging port, that will cause a short-circuit.

Turn off the battery when not in use and before removing it from the e-bike.

Only grab the charger with the plug and not the cable when plugging and unplugging from the wall.

If the battery has trouble charging, discontinue charging and contact eAhora immediately.

Note: Lithium-Ion batteries can be dangerous. Take care when using and charging your battery. Failure to follow the above guidelines could result in damage to property and/or serious injury. Contact eAhora immediately if you have any questions regarding battery safety.
