1. Different capacities, different brands, do not mix old and new batteries. Mixing can even cause battery reverse charging and shorten battery life. The higher the battery pack voltage (the more batteries used together), the greater the impact on the battery life.
2. It is best to charge the NiMH rechargeable battery immediately after use. Do not wait to be charged with other batteries. The storage of the discharged battery will easily cause the battery to be over-discharged and cause the plate to short circuit, resulting in permanent damage to the battery! Do not over-discharge NiMH batteries, especially when using battery packs or low power consumption (such as remote controls), pay special attention not to wait for the electrical appliance to stop working before recharging, which may cause the battery to be over-discharged and greatly reduce its capacity or even permanently at one time. damage. Do not wait until the battery is fully discharged before charging the NiMH battery! Please remember to charge it regularly! picture
3. When using a non-intelligent charger, the charging time must be controlled. Charging time = battery capacity divided by the charging current of the charger multiplied by 1.2 times. Overcharging will shorten the battery life. It is best to use a smart charger to charge the battery (see "Identification of True and False Smart Chargers"). The main problem of false smart chargers is that the battery cannot be fully charged, and some only charge 30-40% and then stop.
4. If the appliance is not used for a long time, the rechargeable battery should be removed from the appliance, fully charged, put into the battery box, and kept charged at least once a year. It is normal for new batteries or rechargeable batteries that have not been used for a long time to have insufficient capacity at the beginning. Under normal conditions, the capacity can be restored after 3-5 cycles of charging and discharging.
5. It is best to store the battery in the battery box. Do not contact acid/alkaline substances. Do not contact with high temperature/humidity to cause rust and damage to the electrodes. If the electrodes of the battery/charger are dirty, you can use a coarse cloth to clean them and recharge them.
