Cordless Drill Batteries

Power Tool Battery usage tips:

1) A new power tool battery usually maintains a discharged condition with very low capacity. It is highly recommended to fully charge new battery packs before using. You can refer to the users' guide of your electronic device for charging instructions.
2) A new power tool battery pack needs to be circled (fully discharged and recharged) three to five times to reach its optimum performance.
3) Rechargeable power tool battery will undergo self-discharging when left unused for a long period of time. Thus, it should always be stored in a fully charged state and kept in a cool, dry and clean place.
4) To maintain the optimum performance of a power tool battery pack, it is highly recommended to circle (fully discharging and recharging) it at least once a month.
It is normal if the new power tool battery gets warm when being charged or used. However, please pay special attention if the battery pack becomes excessively hot. This may indicate there is a problem with the charging circuit of the electronic device. Please consult a qualified technician if necessary.
6) New batteries are hard to be charged. Sometimes, your electronic device may indicate a fully charged condition about 10 to 15 minutes when the new battery for power tool is being charged for the first time. When this happens, remove the power tool battery pack and let it cool down for about 10 to 15 minutes then repeat the charging procedure. Sometimes, the new battery will suddenly refuse to be charged. If this happens, a suggested solution is trying to remove the battery from the device and insert it again.
