Battery Maintainer Not Charging Connected to Cobalt Remote Terminals

[sellanycar]

My Schumacher Battery Maintainer has worked fine for several years in keeping the battery charged in my 2014 Honda Civic. The first time I've used it on my 2010 Chevy Cobalt (attached to the remote terminals under the hood), the pulsating green light that indicates "fully charged" has not come on after 12 hours.

Is there something wrong about charging via the remote terminals?

Check the battery for a bad cell. The resistance in a bad cell will make the charger keep going.

If you have one of those small inexpensive battery maintainers, they aren't meant to charge up a fully discharged battery. They work best on a battery that is already fairly well charged up and just needs a little topping up.

I've had difficulties getting a good connection on the remote terminals. I was trying to jump start a Cobalt once and was unsuccessful in getting it to start with the remote terminals even after making several adjustments to the connections.

I was finally able to get into the trunk and hooked directly to the battery and the car fired right up.
