FAQs

Q: How to check if this battery is compatible with my Power Tool?

A: First, find out the part number of your old battery or the model name of your power tool (e.g., '4P2S') and match it with our product compatibility table. Second, please compare the old battery with our product images to make sure their shapes are the same. Lastly, check that the voltage (rating) is the same as the old one.

Q: Do I need to charge the new battery for 12 hours for the first time of use?

A: No. Lithium-ion batteries have no memory effect, so it’s the right way to charge and discharge normally.

Q: How do I properly charge my battery?

A: Please avoid exhausting the battery power and then recharging, because it will cause a lot of damage to your battery. Therefore, you have to charge it when the remaining power is nearly 10-20%. In addition, if your battery has not been used for a long time, please charge it once a month, keep the remaining power at about 40%, and then store it in a dry and cool environment.

Q: How to care for my power tool battery and extend its life?

A: 

1. A complete discharge would damage the life of the battery for power tools.

2. Please keep the power tools as dry and cool as possible.
