Boat starter batteries recommendations

[fishfoxey]

Finally managed to get up to check my boat , wouldn't start so checked the starter battery voltages and only show 1.6v (so pretty Us I think). Has anyone got any recommendations for A) Good UK suppliers) and B) Best value for money, as I have to replace 2 so cost will be a major factor. Thanks

What sized space do you have?
Two of these would be good as starter batteries if they will fit.

+1 for Battery Megastore. Bought from them over the years and they have always delivered value and quality.

These are the current batteries and they look similar

In the last 35 years, these are the best batteries I've ever used.

663HD's are still available, or at least, something very similar:

They are very nice, but they are £300 quid each, and you might need a different charger for AGM.

Most modern chargers are smart and can be switched to AGM. If I get 10 years from a battery, that's a win for me. Hate lugging Bats up and down marinas, was an Exide dealer for a long while.

I hate failing batteries too, but the last batch of batteries lasted 5 years, and that's good enough for me.
Not all boats have smart battery chargers (mine does, but many older boats don't).

I'd suggest to check the engine CCA requirements, then select a known brand that exceed (or meet) that amount of AMPs, fits the space and has right type and position of connectors.

Longer longer warranty offering can be seen as a manufacturer's trust in own product quality but the best way to help a battery life indeed is a proper charging regime, by engine and/or charger.

Weight is an interesting factor to compare within same technologies. More is better, as a rule.

Ive just replaced my Thruster battery with a new one from this company - they have a sales counter just off the M27 near Fareham - good prices if you can collect.
