Maintenance-free battery widely used in automobiles-Power Kingdom
Most free maintenance battery is made of lead antimony alloy plate gate, charging less prone to water molecules, at regular intervals must check the electrolyte level, such as liquid level is lower than the plate is adding distilled water to higher than the liquid level, also often test acid concentration.
Need to must regularly over a period of time not to use to replace electricity and so on.
Power battery (
Also known as deep cycle battery)
: instantaneous discharge ability is poor, but can depth of discharge, and the amplitude is smaller than start metal battery discharging current changes.
Generally applicable to the golf cart, electric vehicles, forklifts, washing machine, leveraged hoist, new energy, emergency lights, such as casual car used as driving power.
Powered battery can provide continuous and stable power supply.
Start metal battery: instantaneous discharge capability is strong, but not deep discharge, duration of 3 to 5 seconds, generally will find when we start the car, start metal battery continue to launch the bigger the dozen don't move, because start metal battery has an energy accumulation process, not balanced discharge, generally work nor depth of discharge, completely don't need to charge by pulse current saturated, so the battery widely used in automobile, motorcycle, etc used as start engine maintenance free storage battery.
