I am looking into a good reproduction battery, the maintenance free, or AGM style batteries that have the reproduction cases. Has anyone had good luck with any of the various types out there? I do not want to deal with adding and checking electrolyte as offered by some of the vendors out there.

Thanks,

 

Just get one of these and take it to the battery store and find the one that fits best.

I have one of the toppers i will give to who ever wants it I replace mine with a
a R59

 

Very cool! I did not know anyone was making these.

 

I had one in my Plymouth, they stand behind a very good product.

 

I am very mixed on the AGM batteries. I deal with an average of 2000 batteries a year. Half AGM and the other half are standard flooded type.

The AGM batteries are very good as long as they are on a good charging system and NEVER allowed to go completely dead. With a properly maintained charge they will last nearly 10 years. If it goes dead there is about a 75% chance it will never take a charge again. Also, The charging system will NOT charge these batteries, only maintain the charge. If it is dead (no lower than 11.5 volts) it will not be fully charged till you hook up an AGM battery charger. You will need to have an AGM battery charger. Standard chargers are bad for AGM batteries.

I will stick to the flooded batteries myself.

 

You are correct the AGM batteries are a whole different product with a different set of technique. Mind you the company I suggested sell both types of batteries. I only recommend them for a show car as they are pricey.

 

Another note on AGM batteries... We very often hook up satellite tracking systems that use battery power even when the engine is not running. We have seen these AGM batteries get low but still have enough power to start the engine. Then with a low AGM battery the alternator will go to a much higher amp output for a long time and can burn up trying to charge the battery.

 

Great info. I did not know of those issues with AGM type batteries.

Based on personal industrial experience you couldn't give me a gel cell type battery- we had installed gel-cells as an "upgrade", a few months later when we needed DC power to shut down after the station AC auxiliary power failed, as soon as all those DC pump motors kicked in those brand new best-thing-since-sliced-bread gel batteries **** the bed and wrecked a turbine to tune of about $20 million. Mfg tried to say the batteries hadn't been maintained properly, but a new battery charger of their manufacture was part of the installation.

We went back to flooded-cell battery banks soon after.

 

If you would like to read more about all types of batteries and their care, try this out. Lots to read.
