Battery Chargers. Design Note 32


IMAGEPresenting here three circuits to make efficient Battery chargers. The 12 volt Lead Acid Car battery requires high current for fast charging. If we provide high current, the battery will charge within 1-2 hours fully. Usually a Lead Acid battery takes high current initially, which drops to 500 mA or less after 10-20 minutes. As a rule, it is advisable to charge the battery with a current that is 10 times lesser than the battery capacity. The Car battery is 32 Amps or 45 Amps so it requires 3.2 Ampere and 4.5 Ampere current respectively. So the charger should provide 14 volts with a current of 5 Amperes.

Useful Tips to Charge Cell Phone Battery


BATTERY-CHARGING
Mobile phone battery is a high efficient Lithium Ion or Lithium Polymer battery that can deliver much power for long time. In an ordinary Mobile phone, a fully charged battery can power up to 3 or 4 days. But in Smart phones, the battery drains too fast because many applications are running simultaneously. To extend the life of battery we need to know some facts about the charging because the most important cause of battery breakdown is improper charging.

Know the maintenance of Lead Acid Battery


A lead acid battery is composed of series of plates immersed in a solution of Sulphuric acid. Each plate has a Grid on which the active material is attached. In the negative plate, lead oxide is attached as the active material while on the positive plate, pure lead is attached. All the negative plates are connected together. Similarly all the positive plates are also connected together.
