A:We measure the battery open circuit voltage with a multimeter, then we can preliminary judge the remaining capacity of battery. Remove the battery, and measure the battery open circuit voltage by multimeter, then check corresponding remaining voltage in following sheet


Q: If a motorcycle will be stored for a long time, how should Skyrich lithium battery be maintained?

A:If battery will not be used for more than two weeks, it is better to remove the battery from the vehicles and stored. In order to avoid batteries discharging by tiny current in vehicles, which may cause battery failure by overcharge.

Normally, if the full charge battery is stored one year or longer, the left capacity still can start the motorcycle successfully. Accordingly, it doesn’t need to disconnect the battery and motorcycle cable if no current delivers in the motorcycle when the key is off. Mostly motorcycle models produced by regularly manufacturer do not have the current delivers when the key is off.

if additional security installment or control system in the motorcycle, The motorcycle still delivers the current to keep the clock, computer and security installment operating when the key is off. In this case that the motorcycle is in storage for long time, the battery will be damaged in one week after battery full discharge due to lithium engine start battery low capacity. Please remove the battery or disconnect the battery cable if you do not use the motorcycle for two weeks or longer, In order to avoid batteries discharging by tiny current in vehicles, which may cause battery failure by overcharge. Please measure and confirm the battery voltage is higher than 13V before re-installing the battery, or use dedicated charger to recharge the battery 30min if the voltage is less than 13V.

Q: Can I use Skyrich lithium battery normally in low-temperature environment?

A:Lithium batteries cranking performance will be degraded as temperature drops,. However, they still react to cranking under -10℃. Lead-acid battery type will increase resistance on each subsequent cranking attempt, until it won’t turn over. If your Lithium Iron Phosphate battery fails to start on first crank, that first start has warmed the battery, and the second attempt will be much stronger, and so on until you get a good start.

Due to our low resistance formulation, the performance of Skyrich lithium battery under cold conditions is better than other brand lithium battery. During minus 5℃environment temperature, most users can start the motorcycle on first try.

If under low temperature condition, please turn on your motorcycle spotlight after key on, it is good for the batteries because of the current delivery, but the lighting time depending on the temperature. 30 seconds if minus 5℃environment temperature, 4-5 min if minus 5℃environment temperature, this ensures the motorcycle would start on the first try, and protects the battery cycle for longer performance.

Q: How should Skyrich Lithium battery be disposed?

A:Our Skyrich Lithium battery contains no lead or acid; it meets the European ROHS standards for environmental health. Please check with your local authority if LiFePO4 battery is allowed to put into the general dust bin.
