Battery electrolyte level indicator
LED (optional)
There are two versions of the LED:
●
1) Located on the battery
●
2) Located next to the battery plug.
The LED indicates whether it is necessary to
top up the distilled water in the battery.
Operation:
●
If the LED (1) or (2) is green, there is a suf-
ficient level of electrolyte in the battery. The
battery must not be topped up with distilled
water.
●
If the LED (1) or (2) is red, there is an insuf-
ficient level of electrolyte in the battery. The
battery must be topped up with distilled wa-
ter.
