The temperatures for rechargeable batteries are as shown in the table below, and batteries that have become hot should be cooled for a while before being recharged. Table 3 Rechargeable batteries Temperatures at which the battery can be recharged EBM1830, BCL1815 32°F - 122°F (0°C - 50°C) 4. Disconnect battery charger from the receptacle.

When you feel that the power of the tool becomes weaker, stop using the tool and recharge its battery. If you continue to use the tool and exhaust the electric current, the battery may be damaged and its life will become shorter. ⅜ Avoid recharging at high temperatures. A rechargeable battery will be hot immediately after use. If such a battery is recharged immediately after use, its internal chemical substance will deteriorate, and the battery life will be shortened. Leave the battery and recharge it after it has cooled for a while. BEFORE USE Check the work area to make sure that it is clear of debris and clutter. Clear the area of unnecessary personnel.
