Battery Pack Efficiency And Charging Advice 

Recharge the battery packs before they become completely exhausted 

When you feel that the power of the tool becomes weaker, stop using the tool and recharge the battery packs. If you continue 

to use the tool and exhaust the electric current, the battery pack may become damaged. 

Avoid recharging at high temperatures. A rechargeable battery pack will be hot immediately after use. If such a battery pack is 

recharged immediately after use, its internal chemical substance will deteriorate, and the battery life will be shortened. Leave 

the battery pack and recharge it after it has cooled for a while. 

The battery pack should only be used and/or charged when battery pack temperature is between 50C and 300C. 

The battery pack needs to be warmed-up or cooled down in order to prevent damage to the batteries internal components. 

Note: Failure to warm up or cool down a battery pack could result in serious damage to tie battery, charger and user.
