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!
