Lithium batteries are small, abouta third the size of lead-acid batteriesand can be seen at a glance.
The advantages and disadvantages of lithium batteries and lead acid batteries are:
1. Lifespan, lithium-ion batteries 1200-2000 times, lead? -acid batteries? 500 to 900 times.
2. Specific energy, lithium-ion battery 150W·h/kg, lead-acid battery 40W·h/kg.
3. Volume, the volume of lithium-ion battery is 2/3 of the volume of lead-acid battery.
4. Weight, light, only 1/3 to 1/4 of lead acid batteries.
5. Price, lithium-ion battery is higher (24V/10Ah price: 750-1200 yuan), lead-acid battery is lower?
Loading precautions:
1. After charging, first disconnect the mains power, then disconnect the plug connected to the battery.
2. It is prohibited to connect the charger to the power supplypower supply for a long time without charging.
3. Perform battery maintenance every one to two weeks, that is, once the charger's green light turns on, continue charging (float charging) for 1 to 1.5 hours to extend the duration battery life. .
4. Please use the special charger supplied with the vehicle. Do not use other chargers to charge this vehicle.
5. When loading, it should be done in a ventilated and dry place. The charger and battery should not be covered with anything.
6. The charging area must be kept out of the reach of children and hands must be dry when plugging and unplugging.
Generally, detecting problem batteries in problem modules mainly relies on the following points:
1. Appearance, if there is a leak. Flatulence. Problematic battery cells sometimes have effectssecondary obvious, and the battery cell has obvious appearance abnormalities;
Battery bulge
2. tension. This can be measured with a multimeter.
3. Internal resistance. If solder breaks or other reasons occur inside the battery, it will also obviously be reflected in the internal resistance of the battery.
It is actually not recommended for ordinary people to deal with battery failure, because the electrolyte inside the battery poses certain dangers. If not disassembled properly, it may catch fire or even explode.
In addition, voltage and internal resistance testing generally examines outliers. The battery cells in question generally have a significantly lower voltage and a significantly higher internal resistance.
