batteries
What to do with the batteries:
Leave the battery cover open during charge
Never use naked flames or smoke near the batteries
Be careful with the liquid because it is corrosive
Do not create sparks near the batteries
The battery gases are explosive
Do not reverse the polarity
CHECKING THE BATTERIES CHARGE STATUS
This type of check is shown on display.
Charge
when the electrolyte density is 1.260 (30° Bè) at 30°C with the electrolyte at the right
level, between 100% and 75% on display
Partially discharged
if the density is between 1.26 (30° Bè) and 1.20 ( 24° Bè), between 50%
and 25% on display
Fully discharged
if the density is below 1.14 (18° Bè), below 25% on display
DENSITY MEASUREMENT
This check of the battery charge status is done with the hydrometer, when the batteries are charging.
1.
Insert the hydrometer syringe and withdraw a sufficient amount of electrolyte to bring up the
float
2.
Make sure its top does not touch the rubber ball or it remains attached to the glass walls.
3.
To measure the density after distilled water has been added, wait for the density
to equalise throughout the liquid contained in the element
