How to check the specific gravity of the two 12 V batteries
connected in series to a 24 V UPS and inverter ?
will we have to disconnect all the connections and turn off
the UPS and inverter or not ?
will we have to check specific gravities in each cell of
the two batteries ?
what is the name of the instrument that is used to check
the specific gravity and whats the procedure to check the
specific gravity with it ?

thanks

batteries is fully charge and below 1180 means batteries is
dead
hydro metre is used for mearsuing specfic gravity
ok this is the right answer
