Lead-acid battery classification

1) ordinary battery;Ordinary battery plate is composed of lead and lead oxide, electrolyte is an aqueous solution of sulfuric acid.Its main advantages are stable voltage and low price;Disadvantages are low specific energy (that is, the energy stored per kilogram of battery), short service life and frequent daily maintenance.
2) dry charge battery: its full name is dry charge lead-acid battery, its main feature is that the negative plate has a higher capacity to store electricity, in a completely dry state, can be saved in two years to get the amount of electricity, use, just add electrolyte, wait for 20-30 minutes can be used.
3) maintenance-free battery: maintenance-free battery due to the advantages of its own structure, the consumption of electrolyte is very small, in the service life of the basic need not add distilled water.It also has the characteristics of shock resistance, high temperature resistance, small volume and small self-discharge.The service life is generally twice as long as the ordinary battery.There are also two kinds of maintenance-free batteries on the market: the first is in the purchase of disposable electrolyte after the use of the need for maintenance (add a supplement);The other is that the battery itself has been added to the factory electrolyte and sealed, the user can not add liquid supplement.
Lead-acid battery classification lead-acid battery has 2 v, 4 v, 6 v, 8 v, 12 v, 24 v series, capacity from 200 mah to 3000 Ah.VRLA battery is a rechargeable battery based on AGM (liquid-absorbing fiberglass board) technology and calcium gate board, which has excellent characteristics of large current discharge and long service life.It needs no water in use.
