battery question

[528Sport]

Hi,
Not car related. I need a battery for a generator. Costco sell 2 types or battery car batteriers or marine/leasure batteries. whats the main difference?

Looking that them all I can tell is thet on the marine batteries you can top the cells up.

The battery will be on a tricle charger and the crank case is heated.


Thanks

A leisure battery is designed for a slow discharge and even to go flat before recharge hence their use in caravans etc.
A car battery is designed to cope with huge currents on start-up but does not like to be fully discharged.

You want a car-type battery for starting a generator but not one of these crappy ones where you can't top them up ("sealed for life" or whatever just means that the "life" is shorter, with batteries or with anything else really). Marine/leisure ones won't do for the reason given by Steve_D.

What really kills generator batteries is the vibration. You can get batteries which are intended to resist vibration but you'll want somewhere more specialised than Costco.

Thanks chaps. The generator in question is a "mans" generator FG wilson jobbie (27kva) not a B&Q special from china.

I think I will get a Bosch battery that can be topped up (Costco have or did have them)

Thanks for the advice

Oh I also rang FG wilson who said contact dealer network but the all just quote to come and replace the battery. Nearest dealer is 80 miles away and at 45p/mile just in callout would cover the cost of something I can do myself
