My battery charger has died a new one from a marine supplier is about £500.00, is there anything special about it or can i install any heavy duty charger. im in the car buisness and i can get one for about £200.00.
It doesn't say 'marine' on it, so of course it won't work on a boat.
Seriously, as long as it's a proper 2/3 stage charger, it should be OK, I believe. A cruddy Halfords special will cook the batteries if you leave it on too long, but that stands to reason.
Marine battery chargers, are normally, these days, three stage chargers. If you can source a car type, which is three stage, then I see no reason to not use one on board. For explanation of three stage charging, you'll have to look at the literature supplied with each individual charger, most automotive battery chrgers are not three stage. But they are heading that way. What charger were you looking at that was 500 squids, sterling do them quite economically, as do a lot more people. If it's 24volt then I can see the money. I've just boughjt one, check Kev out at yachtbits.
I used a Halfords special on my boat for a while, before I got the Sterling. Cost about £40 and was suitable for leisure batteries too. Seems to be a 2 or three stage charger. Measuring voltages, showed a max over 14v dropping to 13.5-13.8v over time.
I still use it for charging a 110 amp hour deep cycle battery that powers the switch panel (lighting only) in the aft cabin. (am yet to tie circuit into main battery) Had it for about a year and seems fine - even able to pretty much maintain battery voltage while lights on 3 x 25 watt halogens plus 3 x 8 watt strips. (about 8 amps I guess)
Having said that I still bought a "proper" charger for the main bank.
She had a deep, throaty, genuine laugh, like the sound a dog makes just before it throws up
