cycle, you can expect a total life of 4800 hours. Therefore, it is advan-
tageous to use the battery as much as possible during each cycle.
Ni-MH batteries should not be subjected to longer periods of
deep
discharging
, to prevent polarity reversal of individual cells. The
worst thing for a battery is to remain fully discharged for long peri-
ods of time. This causes sulfation, which is a hard lead sulfate coat-
ing on the plates. Sulfation can reduce battery capacity dramatically.
If a battery has been deep discharged, the charge LED will light
green when the mains are connected, and after 3-30 seconds the
green colour will change to orange. If the AC/Charge LED doesn't
change colour back to green within the first 10 minutes, disconnect
the mains supply for a few seconds and then reconnect it.
