=jon= Posted March 16, 2014 Share Posted March 16, 2014 Hi, The battery in my 90 is getting a bit tired - currently it's got what I believe to be a 90Ah Disco battery (it's branded LR but I can't remember the part number off the top of my head) fitted under the passenger seat with a custom battery clamp. I'm likely going to be fitting a winch (just for self recovery, not anything particularly taxing!) at some point soon, so am considering going twin battery, with a split charge system of some form. The landy is only used occasionally, so hopefully I can power the 'always on stuff' like the alarm off the second battery and not have it go flat when left, and also I'll likely also have it set up to use the second battery for lights when camping) What's the recommended setup? I've read on here differing opinions about a big single battery if the winch is only for occasional use, to two smaller batteries with split charge, to exotic stuff like twin sealed batteries.. Any thoughts? If one big battery will do me fine then that's probably going to be the cheapest / simplest options (and just use common sense when camping!). Any advice appreciated! Thanks Jon Quote Link to comment Share on other sites More sharing options...
AndrewHorsfield Posted March 16, 2014 Share Posted March 16, 2014 I would recommend a pair of Odyssey batteries. If you go to the website you can download a spec sheet which includes external dimensions> Then a split charge system. I recommend having one with individual battery display. The T-Max one is probably one of the cheapest, with display. Worked well for several years on my disco until I sold it. Quote Link to comment Share on other sites More sharing options...
miketomcat Posted March 16, 2014 Share Posted March 16, 2014 I have a pair of varta batterys as all these lovely new stop start cars have agm batterys that are a lot cheaper than optimas I'll get numbers later but they are the same size as the gen fitment.

Frax Posted March 16, 2014 Share Posted March 16, 2014 I fitted an x-charge relay with two standard batteries, works fine and did not cost the earth. Depends what you want to spend ? Quote Link to comment Share on other sites More sharing options...
=jon= Posted March 16, 2014 Author Share Posted March 16, 2014 I'm prepared to spend what's necessary - whatever will get the job done without going overboard - so if two standard batteries are OK and I don't need optimas etc I'd save the cash for when something else inevitably needs fixing!

Mo Murphy Posted March 16, 2014 Share Posted March 16, 2014 Jon, if it's just for very occasional winch use, then I would just fit one big battery m8, you don't need anything more complicated than that. Have a look at Tayna batteries who sell Numax batteries at decent prices. HTH Mo Quote Link to comment Share on other sites More sharing options...
honitonhobbit Posted March 17, 2014 Share Posted March 17, 2014 I'd second NUMAX as being the best VFM. Quote Link to comment Share on other sites More sharing options...
tweetyduck Posted March 19, 2014 Share Posted March 19, 2014 You can get in two group 34 in the case or one big one. You might be able to get bigger ones than 34 in but height is the issue for the rear one. If you want to winch you'll need a big relay for connecting them. I got a T-max 250amp. I'd follow the advice and go BIG and go single and don't bother with a split charge or dual battery setup. Quote Link to comment Share on other sites More sharing options...
=jon= Posted March 19, 2014 Author Share Posted March 19, 2014 Thanks everyone... I guess the next stupid question is if I went big single battery, what's the biggest off the shelf one that'll easily fit in there! Quote Link to comment Share on other sites More sharing options...
Ibex94 Posted March 23, 2014 Share Posted March 23, 2014 Second Tayna and Numax went for the lead calcium at ~100Ah and 1000CCA. Not tried in anger yet but quite a battery with a few good reviews. Rob Quote Link to comment Share on other sites More sharing options...

heath robinson Posted March 30, 2014 Share Posted March 30, 2014 We've been using Sheild batteries of late, for both vehicle and off-grid solar stuff, and they're great. Really good pricing too, and being in Yeovil we can just drop in and ask about specific uses, as they're very knowledgable. They have a few branches around the country, but I don't know if there's one specifically near you. Quote Link to comment Share on other sites More sharing options...
