Battery charging

[SKM348]

Have a 2015 3.8. Left door open and drained battery. Finally got trunk open using a pole through the pass through opening (Did not realize there’s a key slot under far right of trunk lid!)

1. To trickle charge or jump start do I have to remove both +/- cables from terminals or can I attach jumper or trickle charger cables with Existing Cables attached?
2. Should I jump or trickle charge it - is one approach better than other. I don’t want to fry anything. Car has 72K on it and battery is orginal but performs well.
3. Do I also remove ‘flat’ positive cable in addition to the cable on the positive post?
4. Any other tips/advice appreciated

Thanks for quick replies!

You do not need to remove the cables. You can jump it to start it up, but if you are not in a hurry, best would be to charge it until it isfully charged.l

Thanks Dale! So either way I don’t need to remove any cables, just hook up either my jumper or trickle charger cables? I was thinking of jumping it off and driving to AutoZone for them to test it .

Trickle charger worked for 15 minutes then trouble light came on on the charger. Directions said trouble means either a short or that battery is too big which I suspect is what’s happening. Next I tried to jump it and all lights came on when I hooked to donor vehicle but would only make a ticking sound with lights flashing when we pushed starter button. I Let go of button and all interior lights were on but it would just not crank. Finally tried revving donor vehicle and that did not work either. I suppose now I have to remove a potentially good battery and buy a new one, all because I can’t jump it.

Should I try jumping again and let donor vehicle run for a while, meaning maybe it needs to build up some juice before attempting to crank it? I’ll give that a try.

Never mind - my wife read the correct part of the manual where it states you jump/charge it from under the hood at the fuse block. There’s a big ‘+’ nut in the FB and a big ‘-‘ nut near the air filter. Hooked it up and it started immediately. Who’s a thought a man wouldn’t read directions properly

It happens to the best of us.

I hook up my trickle charger to the same posts in the engine bay if I plan to park my Genesis for longer than a few days. Works just fine to keep the battery topped off.
