Exide Technologies Section 92.30 - Manual (Page 16)

The suggested frequency of record taking is the absolute minimum to protect warranty. For system protec-
tion and to suit local conditions or requirements, more frequent readings (quarterly) are desirable.
SECTION 12 - TAP CONNECTIONS
Tap connections should not be used on a battery. This can reduce battery life.
SECTION 13 - TEMPORARY NON-USE
An installed battery that is expected to stand idle for over 6 months should be treated as follows:
A. Give the battery an equalizing charge. Following the equalizing charge, open the connections at
the battery terminals to remove charger and load from the battery.
B. Every six months, temporarily connect battery to charger and give an equalizing charge.
C. To return the battery to normal service, retorque all connections per Section 7.3 and then re-con-
nect the battery to the charger and return the battery to float operation.
D. If the battery is standing at an elevated temperature, corrections to the time period to equalize
charge should be corrected per Section 4.1.
SECTION 14 - UNIT CLEANING
Periodically clean unit covers to remove accumulated dust. If any unit or parts appear to be damp
with electrolyte or show signs of corrosion, clean with a solution of baking soda and water or iso-
propyl alcohol, and re-examine within 30 days to determine if the condition re-occurs. If so, contact
your local GNB Industrial Power representative.
Do not clean plastic parts with any solvents, detergents, mineral
spirits, or spray-type cleaners other than those mentioned here as
these can cause crazing or cracking of the plastic materials.
