How can you check your battery is ok.

[John Mason]

Thank you all who contributed with suggestions and advice. I did the checks Andrew outlined and all led me to the conclusion that the battery had given up the ghost. I think the cause was not giving it a low short charge during the winter to keep the charge good. Colins chart confirmed this with the voltage readings and chart. As if I had not got enough evidence to make things really certain Grahams last post just added to the certainty. Then my son (who has much better eye sight than me) put his twopence worth in and said,”There are only two of the cells making bubbles dad.”
Tony thanks for the advice on where to buy a new battery. I will be contacting them.
