Hi all.
Tried to start the car today - nothing. I removed the battery (RAC XM400) to charge. It has 6 cells, the cap of the 4th cell (from the positive) has some kind of glass electrode attached to it. What is it? Can I safely charge with this cap unscrewed?
Second question is....where best to buy a replacement battery. Halfords have one for £56 but I'm sure I can do better.
Car is an N reg (Aug 1995) Ford Escort.
Thanks,
Vin
