Take advice from pappajohn, car headlight bulb the best way.Hi everyone
We recently converted to 1 x Lithium (LiPePO4 100ah), after being told our 2 x Bosch L5 013 90ah 800a batteries had had it and needed replacing. However, on connecting them to a charger, they show 14.1v and switch off, presumably because they both think they're fully charged
So, knowing nothing much at all about batteries, how do I know that they really have had it before I scrap them, please?
PS I don't mind if I've been hoodwinked into converting to Lithium. I just want to know that I'm not scrapping perfectly good batteries
