What brand of battery charger is a good car battery charger and how much is it?

Battery chargers generally use imported power modules, which are relatively new electronic circuit intelligent automatic chargers. Low loss and high efficiency. Suitable for battery charging.

Our commonly used batteries are mainly divided into three categories, namely ordinary batteries, dry-charge batteries and maintenance-free batteries. 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.

Disadvantages are low specific energy (that is, the electrical energy stored per kilogram of the battery), short service life and frequent routine maintenance. Dry-charged battery: Its full name is dry-charged lead-acid battery. Its main feature is that the negative plate has a high power storage capacity. In a completely dry state, the obtained power can be stored within two years. Just add electrolyte and wait 20-30 minutes before use.

Lead-acid battery charger:

According to the charging characteristics of the battery, the two-stage charging method is adopted. The first stage charging mode is "constant current mode", that is, before the terminal voltage of the battery is lower than the preset value, the charging is constant current charging; the second stage charging mode is "float charging mode", that is, when the terminal voltage of the battery is high After the preset value, the charging current gradually decreases as the terminal voltage of the battery increases, and at this time, the charging changes to floating charging. When the charging current is less than 0.5A and the battery terminal voltage gradually rises to reach the preset constant voltage value, the battery is basically fully charged (the charging indicator light is off). After that, the charging current only offsets the self-discharge of the battery, and long-term charging also affects the battery. Harmless, that is, the charger can not only maintain the full state of the battery, but also ensure the service life of the battery.

Adopt two-stage charging method (that is, constant current first and then constant voltage method) to automatically charge, fully charge according to the charging characteristics of the battery, which can prevent the lead-acid battery from being overcharged, and can maximize the battery life.
