First, we take a look at nickel-metal hydride (NIMH) batteries advantages: its discharge curve is very smooth, until the power is about to run out, the battery voltage will suddenly drop. Because the nickel-metal hydride battery is nickel hydroxide for the positive and negative energy-hydrogen storage alloy, the nickel-metal hydride batteries and nickel-cadmium battery positive is basically the same, but the negative energy-hydrogen storage alloy materials used to make nickel-metal hydride batteries have a greater energy. At the same time in the electrochemical properties of nickel-metal hydride batteries and nickel-cadmium batteries are also similar, so the nickel-metal hydride batteries in use can completely replace the nickel-cadmium batteries, without the need of any transformation equipment. And nickel-metal hydride batteries do not contain mercury, is very conducive to environmental protection, a slight memory effect.
Ni-MH battery based on the many advantages of buying it is the growing number of users, then in the course of which should also note it? We take a look.
1, note that the temperature of charge, this is very critical. Should normally be in the 0 C to 40 C ambient temperature for charging the battery. Because of lower than 0 C the internal rechargeable battery will not charge properly, resulting in unrecoverable performance continued to decline. Above 40 C in recharge, there will result in possible leakage phenomenon. (This is why a few friends in the over-charging the battery after the hot, pale yellow liquid out of the reason.)
2, try not to use the initial Ni-MH battery trickle charge. However, in the rapid charge battery can 0.033CmA supplement to 0.05CmA trickle charge (fully activated electronic).
Charging the same time to avoid overcharging by trickle mode, this will damage the battery's characteristics, use timers to control the charging time. (Note: "CmA" in the charge and discharge process, CmA a specified size, and said current value of the battery rated capacity, "C" refers to the rated capacity of the battery.)
