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
Answer Posted / neeraj katoch
first the accurate specfic garvity is 1280 which means
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
