6/12 battery

[ChrisCoccia]

I am looking at batteries for my 6 volt truck and I came across something advertised as a 6/12 battery that states it runs the starter motor with 12 v and everything else with 6v. Anybody know anything about this? The site is called Antique Auto Battery.

I'd be interested in this application. Here is the link: http://www.antiqueautobattery.com/prod011.htm

It is near the middle of the listings, not hard to spot.

Worked great. It's got a bit of a Rube Goldberg appearance, but it works as advertised. Gives you 12 volt cranking, 6 volt run. I would suggest first fixing why the 6 volt isn't working right, but if you need a low buck quick fix for hard starting, this is it. If the battery dies in the middle of a trip getting a replacement quickly could be a problem.

I had one of those in my '36 plymouth years ago, then went to an 8 volt, then decided to convert it to 12v w an alternator. the 6/12 is pricey, and the 6 volt bulbs were getting the same way. I was tired of replacing a 6 volt batt every year (car sits in the garage most of the time). Just found the correct bulbs so I can put my original headlight relectors back in and get rid of the sealed beam conversions. Did the same with my 52 1 ton a couple-3 yrs ago. If I had to do it over again, I'd go right to the 12V conversion-but that's me. Mike

I sent Antique Auto Battery a request for more info and here's what I got back...

6/12 info:

The 6/12 battery will start your car on 12 volts then return to 6 volts. This battery is basically 2 six volt batteries in one normal size battery case. There is a series parallel switch that comes with the battery. This switch when wired to the battery and the starter will start 12 volts to your starter and return to 6 volts, so that none of your equipment blows out.

Your start can be hit with the 12 volts millions of times and never be damaged. You can not run any 12 volt accessories off this battery it is for starting purposes only. Please measure your battery tray to ensure proper size when ordering. All of our batteries are dry charge and come with a 4 year pro-rated warranty. If you have any further questions or would like to place an order please feel free to call us at 1-800-426-7580 M-F 8-6 EST.
