At present, our commonly used vehicle batteries are mainly divided into three categories, namely ordinary batteries, dry batteries and maintenance-free batteries.
Ordinary battery; the plate of an ordinary battery is composed of oxides of lead and lead, and the electrolyte is an aqueous solution of sulfuric acid.
Its main advantages are stable voltage and low price; the disadvantage is low specific energy (ie, stored energy per kilogram of battery), short service life and frequent daily maintenance.
Dry-charged battery: Its full name is dry-charged lead-acid battery. Its main feature is that the negative plate has high storage capacity. In the completely dry state, it can save the obtained power within two years. When used, Simply add the electrolyte and wait for 20-30 minutes.
Maintenance-free battery: Maintenance-free battery due to its own structural advantages, the consumption of electrolyte is very small, and it is basically unnecessary to supplement distilled water during the 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 a normal battery. There are two types of maintenance-free batteries on the market: the first one requires no maintenance (addition of replenishing liquid) during the one-time application of the electrolyte at the time of purchase; the other is that the battery itself has been charged with electrolyte and sealed off at the factory. The user can't add supplemental liquid at all.
The following 7 points are used for the correct use and maintenance of the battery:
1. Check if the fixing bolt of the battery on the bracket is tight. If the installation is not reliable, the housing will be damaged due to the running vibration. Also, do not place metal objects on the battery to prevent short circuits.
2. Always check if the pole and terminal are connected reliably. To prevent oxidation of the terminal, a protective agent such as petroleum jelly can be applied.
3. It is not possible to check the battery's power by direct ignition (short-circuit test), which may cause damage to the battery.
4, ordinary lead-acid batteries should pay attention to the regular addition of distilled water. The dry charge battery should be properly charged before use. As for the maintenance-free battery that can be added with water, it is not impossible to maintain proper inspection. If necessary, supplement the distilled water to help extend the service life.
5, the air hole on the battery cover should be smooth. When the battery is charged, a large amount of air bubbles will be generated. If the vent hole is blocked, the gas cannot escape. When the pressure is increased to a certain extent, the battery case will burst.
6. There is often a yellow-white paste around the battery pole and cover. This is because sulfuric acid corrodes the root column, line card, and fixing frame. The resistance of these substances is very large and should be removed in time.
7. When the two batteries need to be used in series, the capacity of the batteries is preferably equal. Otherwise it will affect the battery life.
