Looking for a couple of 180Ah Domestic Batteries as ours don't seem to hold charge for too long now. Read the article in MBM, but can any-one recommend best make for gel, and fair priced online store?
So-called leisure batteries have been known as a rip-off for quite some time. A sealed battery with a 4 year warranty is just the job for about £70. If it fails in the 4 years, no-one will know that you used it for a boat! Yes you can mix different Ah.
Also, buy a solar panel battery charger off eBay for about £50. It tops up both your batteries while you are away from your boat.
