battery options

[96terrano]

Was wondering what's à better option, getting a massive battery or making à split charge system? I'm running a lot of lighting and a large stereo etc, spit charge would be cheaper I guess:nenau

What amp you got in there now then Ryan? Also the extra lights you have put in are LED aren't they ?
So even with an active sub you wont have that much more than std I dont think. So go for as near to 900-1000 A/H battery as you can afford :thumbs

Ahh right, so a fat battery is better than a split charge then?

Well it's a damn sight easier and cheaper and well proven. I've probably got more load on my stereo than yours and the winch and my lights are old skool halogen etc. Never had a problem.
Get one of these http://www.ebay.co.uk/itm/12V-110AH...tEquipment_Accessories_SM&hash=item2c60d92d60

Unless your running a winch or running a fridge overnight then no real need for a split charge if you want to keep it cheap.

Have you started your driving lessons yet?

mine is 110 amps though:doh

then if it's still working stay as you are :thumbs

So what's the problem again ?

Goes flat randomly. Won't hold charge

probably your dodgy wiring :lol

Nah, there's nothing draining it.

Sounds like battery at end of its life then. Do you know how old it is. These cold mornings over last few weeks are hard on aged batteries

I put one of these on in Nov. Its been great so far. Fits perfect as it flares at the bottom.
I picked it up from the place as it's local to me. http://www.ebay.co.uk/itm/NUMAX-100...ent_Accessories_SM&hash=item2c63c81544&_uhb=1

It was new 'supposingly' when I got the truck back in march 2011. I'm wondering if the dealer just cleaned it

I'm stil looking for an engine to power me alternator

You can parallel two, three, four ..... batteries together no problem. Even the lowest spec alternator will charge them to full potential - just remember to have an isolator switch at each battery.

If you have a massive capacity and don't use it to below 60% then the plates will calcify and the capacity of the battery will diminish fairly quickly. When you manufacture a car, you don't just point a stick and say " that battery over there " The Amp hour rating is calculated to the predicted duty cycle of the battery so in most cases, if you put a bigger Ah rated battery in, you are wasting your money.

If you are using most of the capacity of the battery driving winches and other equipment then there is no problem as long as you don't drive it down to 2volts as drawing current from the battery at this voltage does permanent damage. just remember that full lead acid batteries that are not exercised also die young.

As for leasure batteries - waste of money. A leasure battery for my boat is double the cost of a normal car battery of the same Ah rating 60AH. The boat only gets used half the year and a normal car battery lasts me 4 years. Do the maths and tell me that a leasure battery is going to do 8 years on my boat. :lol

Leasure batteries have thinner plates and don't like very heavy loads e.g. starter motors - they tend to warp and cause internal shorts in the cells.... they are good at what is on the side of the tin - Leasure - not grunt.

Thanks, some good information there:bow:thumbs

Here we go again, I don't understand . My "Leisure" battery in year 3 now and always spins up the motor a goodie. 1000 CCA and 110 amp hour. Use my winch a reasonable amount . Marine use too as I have a similar one (lower ah) on my boat, that's doing starting all the time, then gets to hang around for a week or two.
I've heard about cheap batteries having thinner plates but theses Numax ones seem heavy enough to indicate a reasonable amount of lead in there (relative guess )
So I still reckon 70 odd quid for it seems a good deal :nenau
