Battery Fitting Mistakes

Can you fit your own battery? You sure can. But you should know three common battery fitting errors.

1 Removing car’s computer power – Some cars won’t like to have their batteries removed. It causes the computers to lose track of the sensors they use to manage various systems.

2 Connecting a battery up backways – This is a really common issue and can be spendy to fix.

Anyway, we will avoid these common issues because we will follow some basic battery fitting tips.

3 Failing to calibrate the Battery control module

1 Removing the car’s computer power

This doesn’t tend to be an issue with regular family cars, but the more sophisticated the car, the more computers, and the more likely removing the battery will cause issues.

What type of issues? Mostly irritating type stuff like inop HVAC systems or erratic window controls and poor quality gear changes. And in most cases, these issues fix themselves by just driving the car. (my favorite type of problem)

But sometimes, you have an erratic idle that won’t fix itself and may require a visit to a dealer to set it straight again.

I advise folks who are going to change a battery to use a KAM (Keep Alive Memory) tool; it sends a small voltage to the car’s computers to keep them alive while the battery is disconnected.

2 Connecting up the battery backways

In many cases, connecting up backways just blows a fuse, no biggie, right? And hooking up backways is an easy mistake to make, and it often stems from trying to fit a battery that isn’t suitable, poles on the wrong sides, etc.

But for some unlucky folks hooking up backways can result in some spendy repair bills.

I wrote a post about hooking up your battery backways, and you can check that out here – “Battery sparked now won’t start.”

I also wrote a post about battery terminal identification, and you can check it out here Unmarked car battery terminals.

3 Battery Control Module

Modern vehicles use a computer specifically to manage your battery health; when you replace the battery, the battery control module (computer) should be calibrated – You tell the computer, ” Hey, I’m a new battery, and you don’t need to charge me at the same rate you did the old battery.

If the control module isn’t notified of the battery change, it may overcharge your new battery, which will shorten its life. Anyway, I wrote a post about swapping out your battery, it covers all of the above in more detail, and you can check it out here – “How hard to change a car battery?
