The charging modes of the two batteries are completely different. Never use a lead-acid battery charger to charge a nickel-metal hydride battery, otherwise an explosion may occur.
Lead-acid battery chargers are usually set to a two- or three-stage charging mode. The voltage levels of nickel-metal hydride batteries and lead-acid batteries do not match. There are many types of nickel-metal hydride batteries, and the battery performance and battery protection board parameters may be different. Therefore, nickel-metal hydride batteries do not have a universal battery charger like lead-acid batteries. Generally speaking, nickel-metal hydride batteries are equipped with a special charger when they leave the factory. To protect NiMH batteries, a special charger is required.
The following elements must bebe taken into account when charging nickel-metal hydride batteries:
1. In order to extend the life of nickel-metal hydride batteries, nickel is used. -Metal hydride batteries must be charged and discharged frequently. Make it a habit to charge after 80% of the battery is used. Do not wait until the battery is exhausted before charging it. Additionally, nickel-metal hydride batteries should not be stored for long periods of time.
2. When charging nickel-metal hydride batteries, you must use a corresponding charger. Since the battery raw materials and production processes of nickel-metal hydride batteries are different, the technical requirements of the charger are also different. , so you can only use a dedicated charger. Charging can extend the life of nickel-metal hydride batteries and avoid pfor safety.
3. When the nickel-metal hydride battery is discharged, the power supply should be turned off and the recovery voltage should not be used to avoid serious power loss and prolong the life of the battery.
4. When charging nickel metal hydride batteries, charge for 1-2 hours after the charging light shows full power. It is not advisable to stop charging immediately.
5. When charging, it is best to turn off the device and not use it while charging. When charging, it should be fully charged at one time and should not be charged multiple times.
6. Electrical appliances should not be stored in a low-power state. Therefore, when the battery is not in use, it should be fully charged once a month.
How many 48 V Ah chargers should you use for 4 batteries12 V 60 Ah water heaters for battery cars?
According to the conventional charging configuration, the configuration goal is nine hours of full charge, 72 volts and 20 amps, and a two-amp charger. 72 volts and 30 amps, equipped with a three amp charger. The charging current can also be increased appropriately to accelerate the charging speed and shorten the charging time. Note that the maximum current increase should not be more than doubled.
Once four 12V60Ah batteries are connected in series, it becomes a 48V60Ah battery. Using 48V charger, the charger output current can be higher or lower than 60A. If the output current is 60A, it will take 1 hour to fully charge. If it is above 60A, it will take less than an hour for a full charge. Its value affects the time taken to fully charge.
