Battery charging

[OcalaRoadKing]

Hello all.

After I've had my 69 out for a ride, I place it back on the charger (Battery Tender Jr by Deltran) and the battery always needs some charging. Is this normal, if not, can you give me some diagnosing ideas.

Thanks,
Mike

Mine does the same!! And my battery Is new, But only for about a Minute and then goes to green. I think that is normal. Never had a problem starting

Mine is the same way, once it goes on the tender it needs a brief charge then green.

Check cells, make sure all are full, check voltage and make sure at right level, could also be normal for most battery chargers to start up and then see how battery reacts and go to green if good.

Roger that- agreed charger is working fine. How my 3 work anyways.

Sound's like you ok and so is the battery.

Thanks everyone. The tender goes back to green but it takes some time. I'm talking hours. The battery is a brand new Interstate. The starter kicks overfine and seems strong. Alternator is brand new. I was thinking about calling the alternator manufacturer and see what they say. It may be like you're saying normal but it's the length of time it takes to go back to green is what's puzzling me.

Did you try a different type charger. It may be the sensing unit in the charger. Depending on these newer unit's it may go to a 2amp trickle that is why it takes so long to charge what is remaining to top the battery off. Just a thought.

You're right. I do believe the Tender Jr. is a 2amp trickle charger. I'll try something different and see what happens and let you know. Thanks!

Russ has a good point but don’t forget a trickle charge isn’t a quick recovery type. A volt meter would answer all questions.

Just to say if it crank's good then after driving it and shutting it down for a while like a few hours or so. Then it cranks good then you don't have any problem's.

That's what I was telling myself but I guess I wasn't listening to myself! It's great to have this group and be part of it. So many members with so much experience, especially with the classics. Can't beat it. Thanks to all and thanks Russ.

Don't feel like your the only one that does that. Second guess my self all the time. If I ever get this runner done maybe we can meet up and compare car's. Russ.

Sounds good.

keeping battery clean and dry is the key. in the car or out for storage, clean and dry. as far as trickle charging, if charger can read a full charge and shut off, i would prefer that. if charger is always on, then you are just cooking battery for no reason. long charge periods generate heat and that causes expansion of the plates and then the material on the plates will eventually start to fall off. that is the beginning of the end for a battery.

Thanks. I like that and will start unplugging the charger after full charge immediately. I appreciate the feed back. Thanks again, Mike

Hey Mike if you don't drive the car that much and it sit's for a long time or when it get's cold Ha Ha. It dose not hurt to have a slow trickle battery maintainer. Most people have them on boat batteries and Golf cart's. They get about the life out of the batterie which is about 4 year's to 5. Just what little I know. But yes don't over charge all the time.
