What about a charger without a charger?
The ordinary 12 volt output transformer can not be charged after rectification. This voltage is too low to charge electricity, and can not charge directly from the output transformer sub pole connection. The output of the pole is alternating current.
Cordless rechargeable drill generally use micro batteries, and 12V battery charging, in principle, the voltage should not be higher than 14.4V, charging current is not higher than the battery capacity is very 1, so meet the above requirements of the charging equipment can. The original or three type special charging equipment is better.
