When Lithium Manganese Dioxide battery for digital cameras charging quickly, you can use the microcomputer in the charger to avoid overcharging of the battery. Today's nickel-metal hydride batteries contain a catalyst that can remove the danger caused by overcharging in a timely manner. 2H2+O2--catalyst-->2H2O, but this reaction is only effective within C/10 hours from the time of overcharge (C=cell marked capacity). When the charging process starts, the temperature of the battery will rise significantly. Some fast chargers (less than 1 hour) contain a fan to prevent the battery from overheating.
Some manufacturers believe that: using some simple constant current (and the current is small) charger, with or without a timer, can safely charge the NiMH battery, the long-term charging current allowed is C/10h (the standard of the battery) Weigh the electricity divided by 10 hours). In fact, some low-cost wireless phone base stations and the cheapest battery chargers work just like this. Although this may be safe, it may have an adverse effect on battery life. According to Panasonic's "NiMH Battery Charging Guide" (link at the bottom of the page), long-term use of turbulence (charged with a small current for a long time) charging may cause battery damage; to prevent damage to the battery, turbulence The charging current should be limited to between 0.033 x C and 0.05 x C per hour, with a maximum charging time of 20 hours.
For the long-term maintenance of NiMH batteries, the use of low-frequency pulse-high current charging method can maintain a better battery state than the trickle charging method.
Newly purchased, or nickel-metal hydride batteries that have not been used for a long time, require an "activation" time to restore battery power. Therefore, some new NiMH batteries require several charge-discharge cycles to reach their nominal charge. If you want to learn more about 3.6V 2000mah Li-SOCl2 battery,you can contact us.
