12V Lead Acid Batteries:

The lead acid battery is a type of rechargeable battery first invented in 1859 by French Physicist Gas ton Pl ante. it is the first type of rechargeable battery ever created. Compared to modern rechargeable batteries lead acid batteries have relatively low energy density  Lead acid batteries suffer from relatively short cycle lifespan and overall lifespan ( due to the double sulfation in the discharge state) as well as low or long charge time.

Compared to modern rechargeable batteries lead acid batteries have relatively low energy density. Despite this, they can supply high surge currents. These features along with their low cost make them attractive for use in motor vehicles to provide the high current required  by starter motors

Types of lead acid batteries:

  • Sealed Lead acid battery
  • AGM-sealed lead acid battery
  • Flooded lead acid
  • Deep cycle lead acid batteries
  • Lead acid overall reaction
  • Batterie Gel
  • Flooded lead acid batteries
  • Gel-sealed lead acid types
  • Marine-specific batteries
  • Open battery
  • Sealed
  • VRLA
  • Standby lead acid batteries
  • Cranking or engine starting lead acid battery

Applications of 12Vlead acid batteries:

The 12 Voltage lead acid battery is used by the starting engineer providing power lights gauges radios and climate control. 12 voltage lead acid batteries used in powering boats cars RVs and other forms of automobiles. Some 12voltage batteries are used alongside generators to generate electricity and power up buildings

Extend the lifespan of 12 voltage lead acid battery:

Keeping your lead acid battery clean is an easy way to extend service life. Ensure the top of the battery is clean and the terminals are corrosion-free.

it is a little-known fact that a dirty battery can discharge across the grime sitting between the terminal post reducing service life. These batteries can be very long-lived if they are charged at a float voltage of 2.20 to 2.30 volts/ cell ( at 25 degrees C) (13.2V to 13.8) for a 12-voltage battery.

This low voltage is to prevent the battery from losing water during long float charging For the battery used in seasonal applications and stored long term fully recharge the battery before sorting. Check the state of charge or voltage regularly.

Should the voltage drop below 12.5 V recharge the battery. It is important to check the battery completely before reconnecting to electrical devices.

Safety precautions of 12 V lead acid batteries:

Workers must wear PPE when handling or using batteries or electrolyte rubber gloves and overall or apron protective equipment if the battery is cracked or otherwise damaged safety goggles or a face shield when working on or charging batteries.

Wear approved safety glasses or goggles and a face shield. Wear proper clothing to protect your face hands and body and make sure the work area is well-ventilated. Never lean over the battery while boosting testing or charging.


  • Cheaper,
  • Power full and easily rechargeable
  • High power output capability
  • Inexpensive and simple to manufacture
  • Mature reliable and well-understood technology when used correctly
  • Lead acid is durable and provides dependable service
  • Capable of high discharge rates


  • Very heavy
  • Batteries tend to be very large bricks because energy density low


How is a lead acid battery made?

After mixing lead powder dilute sulfuric acid and add it to the the surface of the gird and then dry and solidify it that the unformed plate.

Is a lead acid battery AC or DC?

A battery only provides direct current or DC
