Battery Equalizer adfitive

[Donald]

I have a neglected battery that froze and since being on BatteryMinder its gone from 250 to 360 CCA. A hydrometer finds 4 good, one bad and one marginal cells.

Battery Equalizer adfitive is suppose to help disolve sulfation. It's not that much $$ so I may give it a try more of an experiment.

My expectations are low so I cannot be disappointed.

The battery won't be used in a vehicle I drive. More of a test battery.

Anyone tried the stuff?

It may shed the sulfation but it will not transform it to good plate material again. The problem with shedding it is the3 material drops to the bottom of the cell and will short it out eventually. Plus the removed material subtracts from the active material.

Frozen = physically damaged plates, not a sulfation problem. A bulged case is a deal giveaway.

If you can remove the vent caps, I'd probably just crack them and take the battery to 15.8-16.2V to equalize charge. High cells will off gas, weak cells will be brought up to full potential notionally.

But full potential does not indicate capacity. CCA does not indicate lost capacity, it's just a correlation of estimated impedance.

The only way to determine is a good instant current load, at s marginal rate c/10 or so, so if you estimate the battery was say 40Ah new, I might discharge at constant 2.5-3A, and monitor time to 1.72V/cell. If capacity vs new is less than 80% of original nameplate.

New MAXX at Walmart. Pay close attention to the build date which is a colored dot about as big as a penny with a alfa/numeric label. Some batteries on our Walmart's shelf are six t months old. Look for one no older than three months.

I have other batteries, this would be an experiment.
