AEG Protect B. 750 PRO Operating Instructions Manual page 19

When replacing the batteries, heed the following:
Use only identical, maintenance-free, closed lead batteries with
the same specifications as the original batteries. Pre-wired
replacement battery kits which are ready for connection are
available at your specialist dealer.
Risk of explosion!
Do not throw batteries into an open fire. Do not
open or damage batteries (released electrolyte
can damage skin and eyes and can be poisonous!)
Batteries can cause electric shocks and exhibit high
short-circuit currents.
For this reason, implement the following precautionary measures
when working with batteries:
Remove watches, rings and any other metal objects!
Use only tools with insulated handles!
To avoid switch-on current spikes, do not use
i
connecting blocks with central on/off switches.
Switch the UPS "OFF" if it will not be used for a longer period of
time. If the mains at your company's facility are switched off
every night, the Protect B. PRO must be switched off every
evening. Otherwise, the battery will discharge. Frequently
occurring full discharging of the battery should be avoided to
extend its service life!
For your personal safety, never switch the
UPS on if the mains plug of the Protect B. PRO is
unplugged!
