Battery Specification

[Jack// ani]

Hi all,

I just took out a dead Panasonic lead acid battery form my UPS and
trying to understand the specifications written on it

Voltage Regulation
Cycle use : 14.5 - 14.9V
Initial current : less than 2.8A
Standby use : 13.6 - 13.8V

Will anybody please explain it?

TIA

When you charge the battery, limit the applied voltage to between 14.5 and
14.9 volts DC
and limit the current to no more than 2.8 Amperes. As the battery charges,
the current will fall.
If you wish to 'top off' the battery or trickle charge it, keep the applied
voltage between
13.6 and 13.8 volts DC.

Beware that hydrogen gas forms during charging so vent the area.

Thanks Lord. BTW this battery is sealed form every where( as I can
see), so where does the Hydrogen escapes??

Thaks all. A little doubt left..... is there any relation between
maximum charging current and ampere-hour rating of the battery?

Like maximum charging current above was 40% of the AH rating!

Thanks again
