5. Faults
Should faults be detected in the battery or the charging device, contact
your servicing dealer immediately. Keeping records of all measured
data will simplify fault detection and corrective action. A service
contract with your servicing Discover
®
dealer will help to detect faults
in time.
6. Testing
Check that the battery is fully charged, before testing new batteries.
Ensure that a sufficient commissioning charge has been applied and
the battery is fully charged. (Sec. 3.2.1)
7. Storage
If filled lead acid batteries are to be taken out of operation for extended
periods of time, they must be placed fully charged in a dry, frost-free
room. To avoid damage, perform periodical equalizing charging (Sec
3.2.1) or permanent float charging.
8. Transport
Be sure that all cells/blocks are protected against short-circuit. Be sure
to document and transport all cells/blocks or batteries according to local
department of transportation rules and regulations.
9. Recycling
Discover’s lead acid batteries are recyclable products. All Discover
Factory Warehouses and servicing dealers are qualified to accept and
handle all used lead acid batteries. Contact Discover
®
or your servicing
dealer for details.

NOTES:
•
The minimum voltage shown for standby use represents the maximum
available capacity.
•
The minimum voltage shown for solar use represents the maximum
available capacity. It is the lowest LVD setting and should only be used
with Discover’s approval. Systems design to be discharged regularly to
this level will have reduced warranty coverage.
•
The recommended LVD and the LVD required for standard warranty
coverage, is the minimum voltage which represents a 50% DoD.
•
The DoD 60% line, represents the minimum voltage setting to control
the end of each discharge voltage in hybrid applications. It’s always
recommended to implement a supplementary control by Ah counter.
