I bought a 12v 520 amp starting power battery as a dedicated engine start battery for my Beta 14 engine, but Ive had problems with it not holding a charge so not being able to start the engine in order to charge it!
I rowed the battery to shore, charged it christmas eve, then today, checked it again before taking it back to the boat, and found it down at 11.92v
I took it back to Halfords who put their measure on it which came up with '12.05 v good battery needs charging', then the assistant went on to explain to me that I needed a boat battery, theirs were only car batteries, he thought what I needed might be called a Gel battery.
He also said they do not guarentee their batteries for anything other than cars, and that boats break/ruin batteries because they dont have alternators to charge them up again.
I tried to explain to him about boat engines being marinised engines, and that they have alternators too, and that as an engineer, I do know a little about it, but he continued to be condescending and give me a load of rubbish.
