Sometimes your car might just need a jumpstart to get it back up and running. However, this may only fend off the problem for a day or two before you’re back to square one. It’s a much better idea to keep your car battery in good condition. In many cases charging up your car battery will be the answer.

What is a trickle charger?

A trickle charger is the best option to help you keep your car battery from going flat. They provide a low voltage charge to your battery to bring it back up to speed. This slow charge is a better long-term option than quickly topping your battery back up. It’ll help prevent overcharging your battery and will keep it in better condition in the long run.

It’s worth noting that trickle chargers won’t work for batteries that are completely dead. So, if your battery has completely discharged, you may need to perform a jumpstart in the first instance. Once you’ve done that you can keep your battery in a good condition with the trickle charger.

  • Find an ideal ground location – ideally, you’ll be looking for a spot of bare metal on the car’s frame
  • Connect the red clip to the positive terminal on the car battery
