equalizing and exercising [RE-wrenches]

[Geoff Greenfield]

We are instructing our customers with grid-tie battery back up set ups to
exercise 2 x a year with a "simulated" overnight grid outage to bring down
battery voltage.  Then kick back into normal mode for a bulk charge cycle.

Question #1 - how often?  2x per year is my gut answer but....

For the same situation but with flooded lead acid I would like to add an
equalize cycle right after.

Question #2 - should we bulk, float and then EQ the next day?

Question #3 - how often?

Question #4 - how low SHOULD an effective exercise cycle be?  in AH% or in
battery voltage?

Thanks to all who share their time - and thanks to all of us in this
industry in this important time!

For a brighter energy future,
