Bulk Charging
If your argument against AGM batteries is that they have a minimum bulk charge charge requirement. Better read this before you misquote or skew numbers.
When you are "the best" battery manufacturer you can afford to stop slinging BS and tell the truth. Facts that other manufacturers would rather have their shorts pulled down in public rather than have secret specifications exposed.
The only competitor to Rolls is non chinese submarine battery builders like EXIDE in India. The Chinese are buying from THEM.
You don't want to know the price per amp hour. Exide used to build batteries for US WW II submarines.
I hope folks can learn a little and deduce from the Rolls Battery manual.
They warm against over amping in bulk stage. My 10-tons of Rolls Batteries gain max heat soak 9F when saturated voltage charging from 23.80 volts.
