With the engine idling, just after starting, you should see between 14.2 ant 14.7 volts across the battery terminals, anything less and the battery will never fully charge and as a result it's life will be shortened considerably.I've just checked my posts and I bought my Hancook battery 2 and a half years ago. I've kept it maintained all that time and it used to spin the engine over rapidly, I've noticed in the last few weeks that it's just not turning the engine over as well as it used to. Could this be the alternator? I've had problems with the RR batteries since I bought it. Is it an easy job for an auto electrician to test it in situ?
