Description

A lead-acid battery

technical field

The utility model mainly relates to a lead-acid storage battery.

Background technique

Commonly used lead-acid batteries are mainly divided into three categories, namely ordinary batteries, dry-charge batteries and maintenance-free batteries. 1) Ordinary batteries; the plates of ordinary batteries are composed of lead and lead oxides, and the electrolyte is an aqueous solution of sulfuric acid. Its main advantages are stable voltage and low price; its disadvantages are low specific energy (that is, the electric energy stored per kilogram of battery), short service life and frequent daily maintenance. 2) Dry-charged battery: Its full name is dry-charged lead-acid battery. Its main feature is that the negative grid has a high power storage capacity. In a completely dry state, it can save the obtained power within two years. When using, just add electrolyte and wait for 20-30 minutes before use. 3) Maintenance-free battery: Due to its structural advantages, the maintenance-free battery consumes very little electrolyte, and basically does not need to replenish distilled water within its service life. It also has the characteristics of shock resistance, high temperature resistance, small size and small self-discharge. The service life is generally twice that of ordinary batteries. There are also two types of maintenance-free batteries on the market: the first type requires no maintenance (adding supplementary liquid) after adding electrolyte at the time of purchase; the other type is that the battery itself has been filled with electrolyte and sealed when it leaves the factory. , the user cannot add refill at all.

Utility model content

The purpose of the utility model is to provide a lead-acid storage battery, the capacity of the battery is obviously increased, the battery life is extended by 70-100%, the ability of resisting the sulfation of the plate is strong, and the manufacturing cost is reduced.

The technical scheme of the utility model is as follows:

A lead-acid storage battery, comprising a battery casing, the inner chamber of the battery casing is divided into a plurality of battery tanks, a plurality of positive grids and negative grids are arranged in the battery tanks, and a separator is arranged between the positive grids and the negative grids, The positive grids are connected to each other as a whole and connected to the positive terminal on the top of the battery case, and the negative grids are connected to each other as a whole and connected to the negative terminal on the top of the battery case; the top of the battery case has a plurality of Filling hole, the filling hole corresponds to the battery slot.

The utility model has a reasonable structure, obviously increases the capacity of the battery, prolongs the life of the battery by 70-100%, has strong resistance to sulfation of the polar plate, and reduces the manufacturing cost.
