Our 11-page feature about lead-acid batteries (starting on page 6) is one of the more detailed articles we’ve published in CM in recent years. Writer Rob Marshall managed to extract so much information from Yuasa, our technical partners for the feature, that we believe this to be the most definitive piece available on the subject.
Car batteries are tough old things. They have to withstand enormous temperature changes throughout the year, starting cold engines on cars that might not have been used for weeks on end. Thankfully, most of the time, they still give that vital burst of life when the ignition key is turned. We tend to take them for granted until they finally give up the ghost. Back in the 1990s, I had a battery – an AC Delco, if I remember correctly – that gave me nine years of service. Have you had one last longer?
With so many of my cars just sitting around, inevitably some batteries don’t survive and can’t be rejuvenated by jump-starting (via a power pack). Fortunately, I have a smart battery charger to revive/top-up dying batteries when required. Those smart chargers really are worth their weight in gold.
As I’ve said before, I don’t recycle my batteries at the local tip. Instead, there’s a metal recycler on the way to the tip who offers around £4 for a 12V battery!
