How Does a Car Battery Saver Work?

A car battery saver is a device that helps prolong your car battery’s life by keeping it charged when it’s not in use. It does this by using a trickle charge that keeps the battery topped up, meaning that it won’t discharge as quickly and will last longer overall.

Most car battery savers are plug-and-play devices, meaning you simply need to connect them to your cigarette lighter socket, and they’ll start working.

Some models may require you to connect to your car’s electrical system, but this is usually straightforward and can be done in just a few minutes.

Once your car battery saver is installed, it will work automatically to keep your battery charged. You can usually leave it plugged in all the time, although some manufacturers do recommend unplugging it when your car is being serviced or repaired.

If you live in an area with frequent power outages, a car battery saver can also be useful for keeping your batteries charged during these times. This can help to prevent them from discharging completely, which can shorten their lifespan. We would suggest you not leave your lights on. This won’t help your battery charge.

Like most car owners, you probably don’t think much about your car’s OBDII port. But did you know that this little port can be a real lifesaver:

  • The OBDII port, or On-Board Diagnostics port, is a standard feature on all cars and trucks manufactured since 1996.
  • This port allows mechanics and technicians to hook up a diagnostic tool and read any error codes that may be stored in the vehicle’s computer.
  • But the OBDII port can also be used as a memory saver. When you disconnect your battery, whether for routine maintenance or a dead battery, all settings in your vehicle’s computer are reset.
  • This can include your clock, radio presets, and seat position. But none of those settings will be lost if you plug in an OBDII memory saver before disconnecting the battery.

There are a few different types of OBDII memory savers on the market, but one of our favorites is the Harbor Freight Memory Saver (Item # 68893). This handy little device plugs into your OBDII port. It provides constant power to keep everything in its rightful place – no more fumbling with clocks and radios after a battery disconnect!

There are a few different ways to make a car battery memory saver, but one of the simplest is just to use a regular household charger.

Let’s look at the step-by-step guideline:

First stepAttach the positive cable from the charger to the positive terminal on your battery, and then attach the negative cable to something metal on your car (such as a ground wire).
Second stepTurn on the charger and let it run until your battery is fully charged.
Third StepOnce it’s done charging, disconnect the cables and store your charger in a safe place.
