The big question: do battery balancers ACTUALLY rejuvenate modules?

I bought and used the Prolong equipment prior to our old 2010 throwing a code (it never did by the way).

And the Prolong equipment gave another 3 years of use prior to being sold to someone who needed reliable transportation and a hand.

At over 200k miles and a battery performing well, battery balancing does work and is effective for also rebuilding batteries, should the need ever arise.

 

I haven't used prolong and I would not given miles (370K) and other issues(P0420) I have on car still with original battery.
However I have seen all good results for the prolong equipment and would definitely consider using it on my 2018 RAV4H down the line.

 

Battery balancing via a grid charger is much more short lived than other efforts like deep cycling/reconditioning, replacing corroded hardware, replacing bad modules before they go bad via in depth testing, etc..

All of these efforts work together to ensure success... Balancing is just one part of the effort. For me it's usually the last thing I do before I put the car back together. Cars that I do balancing on are less problematic than cars I don't do this on.

 

Don't think of it as something that saves you money. Think of it as something that delays a bigger expense while raising your total cost of transportation.

You get to pay $new_battery_price or $replacement_car_price later instead of now. That's extremely useful for some people, but not everyone.

 

Yes, "Grid Charger" was the original name when Maxx Volts, RB and Prolong were all first getting started. It's primarily a phrase derived from electrical engineers. In automotive terms, it's essentially a high voltage trickle charger. And battery balancer is also the same thing but of a different name.
