6 volt battery, who has the best?
What should the cold crank amps be for a 6 volt battery on a 8BA engine? Other then Optima does anyone have a suggestion what battery to use to have better cranking reserve? What should the output be for the generator on 8BA engine? My battery is a little over 14 months old and has no cranking reserve. I have run 0 and 00 gauge cables to the battery, ground, engine, + to the foot switch, and switch to starter. I have had the starter rebuilt with new armature and field coils. If you don't get it to start in 4 or less tries you can forget it. None of the connections are getting hot, not even warm like bad connections. New starter same as old starter. Had the battery "tested" by the store it came from and they say it is OK. I think not myself. So if I am going to replace it where should I look? Thanks

Re: 6 volt battery, who has the best?
For years I've been using Deka 901MF (it's the only 6V battery of that size I can get in Russia. Very happy - good cranking power, little self-discharge. I bought the first one in 2012, had to replace it in 2018. My car is driven once or twice a month May to October, sits in a warm garage in winter, I don't trickle-charge, just start the car once a month for 5-10 min. Here in Russia it's about $100. I believe in US it should be cheaper.

Re: 6 volt battery, who has the best?
The store you purchased the battery from is what kind of a store? Many parts stores dont know how to test a battery correctly and only have an el cheapo load tester which only loads about 50 amps. The battery needs to be load tested to about 300 amps for 15 seconds but before this test it needs to be charged up. Take it to an AUTO ELECTRICAL SHOP, they can also test your generator and voltage regulator settings. Your generator charging voltage should be at 7.5 volts with about 2000 RPM up on the engine for a couple of minutes. If the charging voltage is lower than that then the battery is not getting enough charge. The best 6 volt battery around these days is the OPTIMA by a country mile. Regards, Kevin.

Re: 6 volt battery, who has the best?
Have you checked the charging system recently? The starting issue may be a symptom of a different problem. Ask me how I know.

Re: 6 volt battery, who has the best?
There are only a handful of battery manufacturers left in the USA, the last 6v I bought was from Tractor Supply, not sure who made the battery. For my wife’s Camry I bought an Optima we’ll see how long that lasts.

Re: 6 volt battery, who has the best?
Why not use the optima ? I have used optima 6 volts for years.Always turn the motor very strong. They last a long time and no maintenance. I have one in my 1946 Ford for 10 years. I would use nothing else. Dave Collette

Re: 6 volt battery, who has the best?
Make sure you use the proper Group (size) battery. Fords used various Group 2 batteries through the years. These were significantly larger than the more common Group 1 batteries used in Chevrolets, Plymouths, and tractors. A lot of places only carry 6 volt batteries in Group 1, so you may have to look a while to find the proper one.
I had a Group 1 battery in my '51 Ford years back. It would start the car fine when cold, but sometimes not when it was hot. I had it tested a couple of times, and they said it was "good". I finally replaced it with the proper Group 2 and the problem went away. I have since switched to an Optima in a faux case (with top), and battery problems are a thing of the past. You might as well go Optima, since quality Group 2 batteries are usually more expensive than Group 1. |

Re: 6 volt battery, who has the best?
I’ve had good luck with NAPA Group 1 batteries but will switch to the larger Group 2 in the ‘37 and ‘40 next time since that’s the correct size (dimensions) for those cars. I usually get about 8 years out of a battery. I charge them once a month in the winter and I keep the terminals and grounds clean ;-)

A starter without new bushings is not a rebuilt starter. Check with who worked on it.

Re: 6 volt battery, who has the best?
Lawson, you're not paying attention. The OP specified Other than Optima.
