What do I need to pay attention to when charging Ni-Mh batteries?

Nickel metal hydride battery incorrect charge will cause serious negative impact on the performance of the battery, for more efficient use of nickel metal hydride power battery, should pay attention to when charging the following items:

1, pay attention to the temperature of the charge, this is the most critical factor in all the charge, usually in the Ni-Mh battery manufacturer product manuals specified temperature (0 ~ 45 ℃) environment, charging temperature below rules can make inside the battery charging is not normal, lead to declining power recovery performance. In the above temperature conditions, there will be a battery hot situation, serious leakage, may be produced when outflow pale yellow liquid.

2, constant current charging the battery, began to try to avoid a trickle charging, from beginning to end with a trickle charge mode will affect battery characteristics, especially in large current discharge cannot be enabled later. But constant current charging should be set after a trickle charging ways, charging to supplement, in order to fully activate factor, supplement the purpose of the loss of power;

Section 3, single use Ni-Mh batteries immediately after the best charging, don't advance, together with other battery charging, because after electric Ni-Mh batteries in the certain time easy to cause the battery to discharge a form plate short circuit, battery permanent damage;

4, to best choice to control charging battery charging current and time of intelligent charger.If is a smart charger only depend on oneself to control charging time (because they do not set the control measures of common charger easily to form).New battery for the first three time charge time is commonly: charging time = (battery capacity/charger (current) x 1.5, daily use of Ni-Mh battery charging time for charging time = (battery capacity/charger (current) x 1.2, because the first three secondary fully activate the cell factor, so the longer;

5, because the average nickel metal hydride battery self-discharge rate of 20 ~ 30%, so best to charge every three months, meaning the same as the above item 3, lest discharge damage;

6, different brand, different capacity of the battery cannot be mixed charging, the charger and the battery does not match the features cannot be mixed charging.
