Thread: Battery Charger for parking up the Defender for a while

Should do the job fine. Personally I'd fork out a bit more for a Ctek or similar quality charger if you can afford it.
A 10 amp output is way more than you'll need for battery maintenance. I've got a 5 amp Ctek and its plenty for a standard Defender battery.

I'm not convinced that have a battery charger hooked up 24/7, I did this with my camper trailer but reckon it decreased life of batteries

I stuck a small solar panel on the draw bar and reckons it worked out better going on/off charge.

No real science attached art from maybe the batteries staying cooler??

Buy a small electronic plug in timer for it and make it come on only for one hour a day.

More likely a combination of battery and charger quality and condition I'd guess if anything.
Proper multi stage chargers are designed to be permanently connected and once they reach a fully charged state just monitor and maintain. I think heat would be a non-issue in this case.

I bought a smallish trickle solar charger with leads of fleabay for around 25 bills recently. It keeps my spare battery nicely charged in case I need it.

Would this work on a 75AH Thumper Battery?

I have one of those too. It sits around sometimes for 6 months +

I normally check the voltage on the battery once a week.Its a varta,cant remember the model, but its a big one that I had in my Rangie and I changed it because it wouldnt start at the repairers(got rear ended). So bought new battery for it and it normally sits around 13.5 volts with trickle charger on it.

I use Ctek 6 stage trickle chargers for all my toys ( trailbikes, UTV's, 4wd ) and they work a treat. I leave them connected permanently when vehicle not in use . Always have a permanent connection to the battery terminal with the lead and plug located in a convenient position to connect and disconnect. Definitely worth the money - have already saved $ not having to replace batteries prematurely
