Thus the level checks are only satisfactory if they are done
almost at the end of the charge (but during the charge).
Leakage can occur during operation if you do not obey these
instructions when you add liquid. The level is correct when the
distance between the seat of the vented filler cap and the
electrolyte is 20 mm (0.787 in) (distance measured in the
conditions given before).
- If necessary,
add distilled water to adjust the level to this
value.
WARNING: DO NOT USE ACID OR ACIDULATED WATER to adjust
the electrolyte levels in nickel-cadmium
cells. A very small quantity of acid is
sufficient to cause permanent damage.
The easiest tool to adjust the level is a plastic syringe tube
(equivalent to that used for medical injections, with a plastic
nozzle on the conical end).
The length of the nozzle which goes into the cell must be 20 mm
(0.787 in) ; this is the distance necessary between the seat of
the vented filler cap and the electrolyte (Refer to figure 501).
To adjust the level,
keep the shoulder of the syringe nozzle
against the seat of the vented filler cap and pull the
plunger up:
