Q1: How to prolong battery life? 

A: Put the battery in cool, dry, good ventilation place, avoid direct sunshine. For long time storage, the environment temperature should be below 30 centidegree. Do not use the battery or charge it under extremely high or low temperature.  Charge battery with correct charger, try to avoid over-charge, use the charger with good monitoring device and best to buy charger and battery kit. If the electrical equipment won’t be used for a long time, it is better to take out the battery or switch off it.

Q2: When can you deliver products? 

A:We can deliver in 10-12 working days if there is stock. For customized battery, it may takes longer.
