CRYSTAL® BATTERY USER MANUAL
SYMPTOM
POSSIBLE CAUSES
ACTION / REMEDY
Battery capacity is low. The bat-
tery accepts charge and does not
get hot but will not hold more
than 80% capacity
No or very low terminal
voltage
- The battery is aging and has
lost capacity through the normal
process of loss of electrolyte
- Undercharged, shorted cell of
broken bus bar internally.
- Broken battery post or bus bar
from overtightening or physical
abuse. Can happen if the bat-
tery is carried by the terminals,
dropped or impacted.
(Common causes of battery
failure)
Perform a purification charge
according to the charge
specifications.
OR
Replace the battery.
- Apply the correct charge to the
battery AND observe the battery
temperature.
IF:
1. The battery takes charge and
stays cool – typical undercharged
condition - perform 2 or 3 more
discharge and charge cycles and
then recheck the battery capacity
2. The battery takes charge AND
gets hot (more than 5˚C (41˚F)
to 15˚C (59˚F) above ambient) –
STOP Charging and contact your
reseller for further assistance
3. No charge acceptance –
potentially a broken busbar
- Check handling procedures or
transport methods
- Check if the resin around the
battery post is cracked.
- Check battery terminal tensions
- if the battery does not take
charge and/or has a low or NO
resting voltage (terminal voltage
with no load at least an hour
after charge) there is a good
chance the bus bar is broken,
OR the terminal has been
overtightened and torn the
post from the busbar.
