I've discovered the battery in my new (s/h) pajero not upto scratch and needs a good charg. The alternator is pumping out 14.75 volts according to my Jaycar multimeter but I would like to remove it from the vehicle and give it a good charge in the garage. I have a newish deepcycle battery that would fit into the vehicle but the question is would it be alright to put it into the vehicle for a week of "mummy going to work" (short runs) or is it beyond the deep cycle capcity?

(nuffin to do with Mackintosh computers)

Thanks in advance.

Have you checked the cells with a hydrometer .... might have a soft one! Better to find out now.

trusty old hydometer said

cell1 1225
cell2 1225
cell3 1200
cell4 1200
cell5 1200
cell6 1200

All in the red.

Is this bad or what?

But is it starting the engine easily? If so don't worry as the cells are reasonably even which suggests that you don't have a faulty cell - just a battery which is a a bit down on charge. Are you a bit of a worrier Russell? Seem to have read a lot of posts about problems! LOL

Oh and if it's not starting the car - straight back to the dealer!

Russell.
To answer your question, no you should not use a deep cycle battery to start you car. THe battery is u.s. so you will have to get a new one so why not get it now, if the battery is showing 14.75 there is very little hope of improving it with a charger. sorry. Eric.

Its not about worrying is about knowledge, if I don't know I ask, I got over the childish quirks of not asking because I might appear dumb. I just don't know, I ask and learn.

I figure if I stop learning they'll bury me.

Its better to ask than to hear "what the" why didn't you ask somebody.

Regards to all.

Also beware of some of those cheap Jaycar Multimetres as I have found they occasionally read over voltage. ie. 14V might actually be 13.2 on a more expensive unit. Not a big drama in most cases, however a few volts here and there can make a difference!
