How To Charge A Car Battery With A Trickle Charger

A trickle charger is a device that provides a small amount of current to a battery over a long period of time. This can be used to maintain the battery’s charge or to slowly charge a depleted battery. Trickle chargers are often used to keep batteries charged in vehicles that are not driven regularly, such as classic cars or motorcycles.

How to Charge a Car Battery with a Trickle Charger

  1. Gather your materials. You will need a trickle charger, a pair of gloves, and safety glasses.
  2. Prepare the battery. Disconnect the negative terminal of the battery from the vehicle. This will prevent any sparks from occurring when you connect the trickle charger.
  3. Connect the trickle charger. Connect the positive terminal of the trickle charger to the positive terminal of the battery. Then, connect the negative terminal of the trickle charger to the negative terminal of the battery.
  4. Set the trickle charger. Most trickle chargers have a dial that allows you to set the charging rate. The charging rate should be set to 10% of the battery’s capacity. For example, if your battery has a capacity of 50 amp-hours, you would set the charging rate to 5 amps.
  5. Charge the battery. The battery will take several hours to charge. The charging time will vary depending on the size of the battery and the charging rate.
  6. Disconnect the trickle charger. Once the battery is charged, disconnect the trickle charger from the battery. Then, reconnect the negative terminal of the battery to the vehicle.
