One point to add to the helpful comment of office888. Batteries will endure being fully discharged a limited number of times. This number is higher for a deep cycle battery which is why they are used for domestic electrics on boats and caravans where they run light loads for long periods and may suffer heavy discharge. A deep cycle should also be used on a rib to run an automatic bilge pump but always in partnership with a starting battery on a separate circuit.

Do I really need a MARINE battery?

Or try an AGM battery. Pricey but you can install and then forget.
Car battery might save you 50 but what's that in boating terms. One tank of fuel? A couple of fenders? One pack of Holt stainless steel washers?

Must admit to having this battery and is now 11 years old and still going strong.

Have purchased batteries off TAYNA http://www.tayna.co.uk/LFD75-Varta-P...065-P3636.html

and found them to be very competitive prices.
Thanks Riber for the specific recommendation

Thanks to all for the advice and info.

I think I' going for the leisure battery and looking specifically for high CCA, although will look at the specific recommendation from Ribber.

I have checked my Varta battery today and can confirm she's still up and running. That's 13 years from new in the boat.

All I do is occasionally hook up up to a Halfords battery charger over winter months.

How is everyone else doing with their choice of battery?

"Normal" battery, ensure everything's switched off and isolater turned off as well. Put charger on over winter, palys run thenging fro c. 15m every few weeks.

Only problems I've had have been from leaving bilge pump on auto and it's rained lots

Group 31 truck batteries are the best thing going.
Many of the truck supply stores have them in my area for around $69.99. (US Dollars)
They have top posts and are made to work hard and perform over the road, can also run more electronics then one would every put on a rib boat.
Most have at least 900 cold cranking amps
When judging a lead battery quality it is all based on weight and a group 31 truck battery is about as heavy as it gets until you step up to 8d batteries.

If money is not an issue the AGM group 31 batteries are hard to beat.

Thanks,
