My batteries keep dying and won't recharge!

Thank you everyone for the help. Could someone reply with a link for a 6 volt battery that is the right size for my 1950 L110? I would greatly appreciate it!

A group 1 will be 9 1/8" long, a Group 2 will be 10 3/4" long, all other dim will be the same. so measure the battery box and see if it is 7 1/8 by 11 or 7 1/8 x 9 1/2" that will tell which size will fit.

I opted for the 8 volt battery in my KB-6 for the cranking power . Really tight rings in a new motor ,Also all new electrical componants and it has been doing fine for about 5000 miles and around 3 years . I think that when I concidered it , I thought of the trickle chargers I have used at other times . Let the frowning begin !!

Unless you re set the regulator to 9.8 volts you will never recharge that battery and will be constantlly dis chargeing while driveing, 6 volt can crank the RED 450 when new, so can crank a "tight" 269 or 308. AT 9.8 you risk overheating a 6 volt coil and loosing spark. I could go on, but if the idea is to make a reliable truck, either fix the 6 volt syystem correctly, or do the work to convert to 12 volt, with the necessary protection for the 6 volt stuff that can't be replaced with 12 volt. 8 volt just adds problems. It is like haveing a leak in a water pipe, and instead of fixing it, jacking up the pressure to get the same flow at the fauset.

Ok thank you, but what is the battery box?

My truck just has a plate that the battery sits on.

Well, measure that and see if the Grp 2 will sit on it, there should be something to hold the battery in place so it doesn't move around while going down the road. I don't have a truck of your model so can't go check myself.

Ok I will go check. There probably would have been a strap to hold it down but that is missing.

The plates measures 13" x 7 1/2".

Group 2 will fit, a group 4 is 13 1/8 so will not.

I noticed that on the battery where it gives the part number it says "1-6VOLT" could that 1 mean group 1?
