What to pay attention to when using nickel-metal hydride batteries

1. Pay attention to the charging temperature, this is very important. Usually we should charge the battery at an ambient temperature of 0°C to 40°C. Because charging below 0°C will cause abnormal internal charging of the battery, causing unrecoverable performance to continue to decline. When charging at a temperature higher than 40°C, liquid leakage may occur. (This is the reason why a small number of friends leak light liquid after the battery is hot after overcharging.) 2. Try not to use trickle charging for Ni-MH batteries. However, after using the fast charge on the battery, you can use 0.033CmA to 0.05CmA trickle for supplementary charging (fully activate the electrons). At the same time, charge or overcharge in standby trickle mode. This will damage the characteristics of the battery. A timer should be used to control the charging time. (Note: During the charging and discharging process of CmA, CmA is a value that indicates the current and the rated capacity of the battery, and C refers to the rated capacity of the battery.) 3. It is recommended not to deep discharge the battery because of the worry about the memory effect. Over-discharge will damage the characteristics of the battery, so pay special attention to the power switch during the discharging process, and at the same time, be careful to keep the battery in the digital camera for a long time. Otherwise, the battery life will be greatly reduced. When not in use within a week, it is best to take it out of the digital camera. Regarding the storage time of high-quality rechargeable batteries, you can rest assured that the storage life in dry and room temperature is about ten years. 4. Although both are rechargeable batteries, everyone should pay special attention to the use of new and old batteries, because even with the same brand of new and old batteries, it will cause damage to itself, and the related circuit parts of the digital camera will also be dangerous. (My Minolta camera's built-in flash was damaged for this reason.) 5. When storing for a long time, make sure to charge and discharge the battery at least once a year (store overflowing, discharge first when restarting, and then recharge.), this is effective Beware of top-notch battery leakage and battery performance degradation caused by battery self-discharge. (Self-discharge rate. 8%/month for lithium batteries; 20%/month for lithium polymer batteries; 100%/month for nickel-hydrogen and nickel-cadmium batteries; 1%-2%/month for lithium metal batteries) ：Some pictures and content of articles published on this site are from the Internet.
