Battery flat from no driving...
Here is one for the Brains Trust...
I have had a knee replacement so no driving for a while. The GC has been sitting in the garage. I thought I better check the battery so I put a voltmeter across the terminals under the bonnet - showed 12.2 Volts.
I started the car and it struggled for a second or two and then started. Normally the start is almost instantaneous. At present it is running in the garage.
I can't take it for a drive, so, what should I do? Leave it running in the garage or put a multi stage battery charger across the terminals under the bonnet or something else?
Thanks in advance.
Cheers
Numb Thumbs

Better that it has a good run, hook up your camper i will fly over and take it for a run to Darwin via Perth for you. By the time i return you should be able to drive again, Jeeps are better driven than left in the shed.

Hi Numb Thumbs,
as I usually only use my GC for towing and trip duty, it often sits in the garage for extended period ie a few weeks. I always connect my spare Ctek smart charger to it and it is always fully charged ready to go.
John.

Thanks, johnnywal, I'll do that. I charging the auxiliary battery at present, so when it is done, I charge the car battery, via the terminals under the bonnet.
Cheers

As an aside to this question, but related - does everyone disconnect the battery terminals when charging their batteries. I do but it's a PITA to reset the security code on the radio when I reconnect everything.

I've never had to enter a security code after disconnecting battery on my 2015.

My JK isn't a daily as I have a Hilux for that so it can sit idle for several weeks at a time. It takes about 4 weeks for my Optima battery to be so low as not to start it.
Get online and buy yourself a Ctek smart charger. These can be bought for around $100 for the MXS 5.0
Connect it to your battery and let it do it's thing.

My Ford FPV GT would take about 3 days before the battery wasn't strong enough to start. A big engine with a small battery. Whenever I wanted to drive it the bloody battery was flat so had to get a smart charger. They are well worth the money.
There is no need to disconnect any terminals.
