How do you know if a car battery is good quality?

car wont start

Car batteries are not just batteries.

The plastic case can contain anything from a carefully engineered plate structure with top quality components and fluids... through to an equally carefully concealed, badly made, cheap and cheerful rack of low quality lead and impurities!

Today, they'll both start your car, and they probably both come with a good warranty.

The difference will only become apparent in a few months or even a year or so, when the cheap battery has deteriorated quickly, doesn't put a lot of effort into starting your car, and eventually... up the ghost in a car park when you return with the Christmas shopping and children that want their dinner or you're miles from anywhere with no phone reception.

The cheapest battery is about much use as the cheapest brain surgeon or the cheapest brake pad.

The battery sits under your bonnet in hot and nasty conditions for years, doing a wonderful job of running your car electrics for what amounts to a couple of dollars per month of battery life. It's one of those places where saving a few bucks will almost always come back to bite!

So we've done the Homework for you

  • We replace batteries every day, so we know, based on the age and condition of the ones we take out, which are good, and which are poor quality.
  • We know who fits the right battery, who just fits the nearest thing they have to hand, and we see some horrors - both in terms of battery choice and the way it has been fitted!
  • If we stock a battery, it is because we are confident of the quality, the value for money and we know and trust the people that make and supply our batteries.
