Current battery choices

I think my main battery has died, currently on charge, but was reading 10v which is never good.

Was all prepared to go and buy what I recall being a popular forum battery of choice, the Numax CXV-X 1000 amp but i went to tanya battery and found that it is no longer available! http://www.tayna.co.uk/Numax-CXV-X-1000-Amp-P7632.html

they offer a similar alternative by Enduroline, but I thought i would see if there are any other currently popular batteries?

The battery on its last legs is an optima yellow top and is used for occasional winching and as the main battery

(its in a land cruiser, shhhhh) but not for anything too strenuous, so i won't be buying another optima.

thanks for your input.

I had a varta on the RRC for 5 years, it had been flattened a few times and used for occasional winching so hadn't had the most favourable life but it still worked. I was having engine problems and after a few failed starts it gave out so I jumped it of a friends oddessey. I couldn't believe how fast the engine turned over, I can't remember it ever spinning that fast. I bought an oddessey pc1500 as a replacement and it's been great so far. Double the price of the varta though.

I have a 120ah numax leisure battery on the caravan which I bought when I fitted a motor mover. I left the caravan at a service place for 2 weeks whilst I was away and when I got back the battery couldn't get the van back on the drive with the motor mover. The only thing that should be running is the alarm so I was disappointed. Unless they'd been doing stuff with it whilst it was in :wacko: I've been advised to put a pair of gel batteries on it but I've never looked into it. The Numax still has 4 years warranty.

No idea what mine is. I went to my local specialist, Avon Batteries in Rugby, told them I needed a battery for a 200TDi Discovery. They looked up the OEM specs and that's what I've got, and it's been perfectly fine for a number of years.

The Odyssey batteries are exceptionally good and will deliver very high current relative to the size or Ah rating. The down side is they are more sensitive to abuse than most more traditional wet cell batteries. Over charging or over discharging see them off fairly quickly. Though, these will see off any battery in time.

I would look for a battery with a CCA rating of around 800A (or higher) - that is, it will deliver 800A peak at 0 degrees C. Your truck needs about 500A to start - and this will deliver that down to about -30C

I would go for a sealed, flooded cell battery rather than Gel or AGM type as they survive abuse better. Gel or AGM are good if you want to mount the batteries upside down and they will work just as well in any orientation. In an ordinary truck, you've got other more important things to worry about if the battery is upside down!

I'd read on a battery website pretty much what Simon has said above, it said that if you have a dumb charging solution then on long journeys you will overcharge the new technology batteries. That's why I went for the Exide EG110B battery, it's pretty much the Land Rover HD battery but 50 quid cheaper.

Yep Ed, modern cars have a more intelligent charging system than just letting the alternator pump out 14-ish volts the whole time, they will use a different voltage for bulk charging than they use for the top up charge, take ambient temperature into account and other things.

A clockwork Land Rover (no idea about any of the ECU controlled engines) will just always charge at the full alternator output voltage.
