BATTERY CHARGE TESTING
Skandic LT E
Hydrometer Test
1. Specific gravity 1.265
A hydrometer measures the charge of a battery in
terms of specific gravity of the electrolyte. Most
hydrometers give a true reading at 25°C (77°F).
In order to obtain correct readings, adjust the initial
reading by
adding .001 to the hydrometer readings
for each 2°C (3°F) above 25°C (77°F) and by sub-
tracting .001 for every 2°C (3°F) below 25°C (77°F) .
This chart will be useful to find the correct reading.

WARNING
Should the battery casing be damaged, wear
a suitable pair of non-absorbent gloves when
removing the battery by hand.

WARNING
Battery caps do not have vent holes. Make
sure that vent tube is not obstructed.
