NiMH No.7 battery

Analysis of the correct charging of NiMH No.7 battery

1. Considering that when a single battery is charged in series, the inconsistency between lithium-ion battery packs will gradually increase. In order to ensure the service life of the battery, the only way to reduce the utilization rate of the lithium-ion battery pack and balance charging is to reduce the inconsistency in battery pack characteristics. It is an effective method that can balance the characteristics of the battery, thereby improving the utilization rate of the iron phosphate battery pack and significantly extending the life of the battery pack.

2. The temperature when charging the NiMH No.7 battery is preferably within 0-45°C. This temperature is more conducive to the active chemical properties of the lithium-ion battery pack, making the charging efficiency higher.

3. Charging is an important step in using lithium-ion batteries. Proper and reasonable charging is very beneficial to extending the life of the lithium-ion battery pack, while brutal and random charging will have a great impact on the battery life. Regarding the charger of the NiMH No.7 battery, it is best to use the special charger provided by the manufacturer. Do not use other chargers of other models or those with inappropriate charging voltage.

Can chargers for lithium-ion battery packs and lead-acid batteries be mixed?

Since lead-acid battery chargers are generally set to two-stage or three-stage charging modes, the voltage levels of lithium-ion battery packs and lead-acid batteries do not match. There are many kinds of lithium-ion batteries, and the battery performance and battery protection board parameters may be different. Therefore, lithium-ion batteries do not have universal battery chargers like lead-acid batteries. Generally speaking, lithium-ion batteries are shipped from the factory with a dedicated charger. To protect lithium-ion batteries, a dedicated charger is required.

Although the NiMH No.7 battery has a protective plate, it can theoretically protect it when overcharged or overdischarged. If the overcharge protection voltage is often triggered during charging, then the output voltage setting of the charger is incorrect.
