Stand Alone Charger
Hi all, What is the best stand alone battery charger? I have had a couple of Shcumachers and I am really not impressed. Also, there seem to be several dozen Schumacher models, how the heck do you k...

To determine whether a battery is or isn't having charging forced down its throat...
A good charger has a set voltage limit. Just like a car alternator.
Charging to "absorbed voltage limit" is the fastest safe way to recharge a flooded lead acid or good quality absorbed glass mat battery.
When it's cold the following voltage limits can be tweaked upward to compensate.
14.7 for high antimony flooded lead acid
14.4 for good quality AGM batteries
When my battery bank is low, it will accept 685 - 690 amperes. Keep in mind it is a 10-ton 2-volt 24 battery bank.
I start the chargers, set the timer and walk off. When the generator burps, I know the timer has shut off. Doesn't hurt a damned thing to slightly over-time the length of charge. Same thing as say a 7-hour drive versus a 4-hour drive.
The incredible longevity I get with my batteries proves irrefutably that my protocol is not incorrect.
