One or all six?

[Joel Craig]

I understand. Is anyone looking to purchase 6 used Five-year-old 6volt batteries?

[Joel Craig]

Haha!

[Joel Craig]

can anyone recommend a brand ?

[Joel Craig]

And Thank You, Very helpful.

Trojan, Crown, US Battery are your top three... I'd shy away from Energizer as sold in Sam's as they rarely last more than few years...

Energizer in my cart are 7 years old. Weren't kept up the best and still have maybe a 10 mile range!!!

The ones at sames are only like 115AH though . I think that what these are. Batteries plus also has energiser. 3 different capacity ones. Johnson controls makes them and lots of other third party batteries.

That said I'm pulling out the energizer batts.

It was my step grand dad's cart. He used it in his tiny like 1/10 acre lot to hold yard tools and such and ride on. Step dad said he would run it for a few weeks till it needed a charge then plug it in!!!

There are always exceptions to the rules some batteries refuse to give up the ghost.

Just pulled a set of 8D batteries out of the ship that were closest to 10 years old and they were still holding their line. Since they were not mission critical I've left them in service beyond our self imposed 4 year duty cycle. The batteries right next to them getting the exact same service had to be replaced twice in 10 years...

I'm curious what the consensus is to which is a better indication of battery health. The "at rest" voltage after charge or the age? I would think the "at rest" voltage is more accurate. Assuming this to be true, what "at rest" voltage would indicate your battery is on its deathbed?

If your batteries only charge to 90%, how long before they only charge to 60%? Is it a slippery slope? Meaning if from 90 to 80 lasts six months, will it only charge to 70 in three more months?



As to the OP's predicament, this maybe the best advice, if available.

Actually I'd be more inclined to look at "IN USE" voltage when considering battery health... I've seen many batteries from motorcycles, to lawn mowers to on board ship that held voltage just fine while at rest that would flat fall on its face when asked to deliver the amps... If based solely on at rest voltage if the battery is not holding 85 % SOC then I'm not risking fun or safety on it myself...

In Use Voltage and Range are what you need to look at for battery health.
