I'm thinking of replacing the battery on my RRC - it hasn't failed me yet, but is always a bit slow to start on cold mornings and even though I have put it on charge for a good couple of hours, it never reaches (fully charged) so am dubious as to how long it will last.

Can anyone recommend a good battery, or what to look for? I seem to remember a feature in LRO a couple of months back but gave the mag away! :doh:

Numax all the way! Swapped my battery out earlier this year and what a difference, so much more cranking power and although it isn't really cold yet I haven't noticed any difference even after its' been standing for a week. Apart from that a Numax battery is cheaper than most standard 072's or whatever they are now.

I think it depends on what your RR is used for Mike, obviously if you run a winch then greater staying power is needed but if not then a standard battery from your local auto-shop will be perfectly adequate. Experience over many years/vehicles has taught me the futility of paying silly money for batteries, as one that costs twice the price (of a standard) never lasts twice as long. My current (no pun intended) battery cost about £60 & is still giving faultless service after 2 years, despite the fact that the RR only gets used about once a week, usually covers less than 30 miles in the process & it never needs charging from an outside scource. It sounds likely that your problem is associated with the charging circuit, put a meter on the battery terminals (after a run) & you should be getting at least 14.4 volts with the engine running.

OK, found these two, both of which are the right size, anyone got a preference to either?

Alphaline: 72Ah, 610CCA, 4 year warranty, £62.95 delivered: Alphaline / n/a / Battery

Numax 072: 70Ah, 550CCA, 3 year warranty, £64.65 delivered: 072 Numax Car Battery 12V 70AH - Car Batteries - Numax Car Batteries

The Alphaline seems to be a better spec, long warranty and a bit cheaper, but never heard of them and have heard of Numax! Thoughts??

You pays yer money (etc) Mike. Like many electrical products the 'unknown' may well be made by a household brand manuf. Don't get over excited by the longer warranties offered by some though, many are only actually for one year & then replacement is at the percentage of unused warranty. So if the battery fails at 18 months into a 3 year warranty you'll have to pay half the (current) price of a replacement.

Thanks norseman! I ordered the Alphaline earlier today for the great CCA, hopefully it won't be totally crap!!
