Archived battery problems?

[timelessconstructionllc]

I have 3 halogens mouted to the bottom side of my toolbox lid. Last night I left them on accidentally and this morning my truck was stone dead. I had a buddy jump me and truck ran fine I idled it for ten nor 15 min then drove it about ten miles then idles another ten min then drove about 20 miles. On the 20 mile trip, not thinking, I turned on the AC. My voltmeter went way down to the point my truck would hardly run then turned off the AC bug it went to bogging down etc. I have two 6 month old interstate batteries. Shouldn't the alternator have charged them. Right now I'm on the side of the road waiting for a jump. Any advice would be greatly appreciated.

I've had a simular experience. Once your batteries are drained, at least one battery creates a dead cell, which means you have to replace both batteries.



Costco's batteries are one and exactly the same as Interstate, which are made by Johnson Control. The Costco Kirtland batteries are much cheaper and have the best warranties.

OP seems to have made duplicate / continued post in the 3rd Gen forum.

You need to charge them independently with a battery charger. Your alternator is not designed to charge batteries. It is used to support the electrical load of the operating system of your vehicle, lights, A/C, ignition, etc. , and restore the power used to start. If you try to charge severely drained, dead, or bad batteries, you can and will cause an overload condition in your charging system. To protect its self, you will cause the breaker to trip and it won't charge at all until the breaker resets itself. If let go long enough, you can burn up your altenater and/or computer that controls it.
