CHAPTER 5
SEALED LEAD-ACID BATTERY (GEL)
5-1 Putting into Operation.
NOTE
Sealed lead-acid batteries are delivered already filled and charged.
In this state they can be stored for 24 months. They must be put into operation
before the end of this period, at the latest.
The sealed batteries and must remain sealed, and should not be opened as
this will damage them.
The batteries are pre-filled and pre-charged. They contain enough electrolyte
to last their life time.
Do not try to check the level of the electrolyte, or add distilled water.
5-2 General Instructions.
1. Because of the 24 volt system in military equipment, batteries are used in sets
consisting either of 2 units connected in series, or 4, 6, or 8 batteries
connected in series/parallel resulting in a nominal voltage of 24 volts.
2. If sealed the individual batteries must be the same type to allow this battery set
to operate correctly and not degrade its service life.
WARNING
Do not use open and sealed lead-acid batteries together
in one set of batteries. May cause damage to equipment.
