Battery Charger.
« on: 19 April 2010, 21:49:04 »
Think it's time to consider a battery charger for my cars, I have brand new batteries on each, the Gls battry will probably have spent most of the last year discharged, the Elite was last used at christmas and will be flat.

I also have both of the old batteries from the cars. 

Am I best getting a normal battery/trickle charger or one of these smart type ones.

If I get the smart type can I keep 2 batteires (In parallel) connected to keep charged up.


Any recomendatios as to make/type.


TIA.   :y

I have a Ctek XS3600 battery charger. If you have 2 batteries that are charged I would think that something similar would be able to maintain a charge on 2 in parallel.

Agree with Andy ... CTEK 3600 is probably the best charger I've owned in 40 odd years.. :)

Just found a few add on items.

Didnt think it was a good idea to leave a battery charging whilst it was all connected up.

That's correct of an olde fashion 'normal' charger, but these inteligent/smart chargers are designed to be left connected fro ever if you want. they monitor the battery state & top it back up as it discharges.  ;)

So one of these wiring kits with a lead from the main run into the car then would be ok.

How long would it take to charge a completly flat battery.

The kit is just a variation on the fixed wiring kit that comes with all the CTEK chargers, it just makes connecting up easy, particularly for car with hard to reach batteries, & gives you an idea of the battery's charge if not connected to the charger.

Divide your battery current rating  by 3.6Amps  :y  :y  :y

Right, I am thinking of adding one of these to the battery, allthough the leads will need extending  I want to fit the CTRK coupler somewhere on the out of the body.

Any suggestions where to fit it?  Reason for this is the car is parked of for weeks on end and rather than struggle opening the car looks I can just plug the charger in and use the remote., front grill is one option I was thinking of, annother was modifiying a trailer plug as I believe there is a constant live on it,

So long as you remember to double up on the current as well as take one or two other things in to account (such as resistance, impedance, Ah ratings, etc)

I'll do the math in 5 seconds flat once I know the specs of the battery/batteries.
