ENGLISH
Observe these instructions and keep them
located near the battery for future reference.
Work on the battery should only be carried out
by qualified personnel.
Explosion and fire hazard. Do not short circuit,
use insulated tools.
Do not smoke or introduce sparks in the
vicinity of the battery. Explosion and fire
hazards are present.
Electrolyte is strongly corrosive. Under normal
conditions contact with electrolyte is impossible.
If the housing is damaged the electrolyte can be
available.
While working on batteries wear protective
eye-glassing and clothing. Observe accident
protection rules.
Batteries are heavy. Ensure adequate mounting
security and always use suitable handling
equipment for transportation. Batteries must be
transported in an upright position.
Any acid splashes on the skin or in the eyes
must be flushed with plenty of water
immediately. Then seek medical assistance.
Spillages on clothing should be rinsed out with
water.
Metal parts of the battery are always alive. Do
not place tools or other items on the battery. Do
not wear any metallic items such as watches,
bracelets, et cetera.
General
Mastervolt AGM batteries are immediate ready for use.
Installation
Prior to installation check battery for mechanical
damages.
Recommended torque for screw connections: 35 to 48
InLbs / 3.9 to 5.4 Nm.
Installation angle of the battery: 180º. Installation in
upright position is recommended.
Keep >0.5 inch / >1cm space between the batteries.
Keep away from heat sources.
Allowed operating temperature:
–4 to 131ºF / –20 to
55ºC; Nominal operating temperature: 41 to 95ºF / 5 to
35ºC. Recommended at 77ºF / 25ºC. The battery life is
halved for every 18 ºF / 10ºC of rise in temperature.
Lower temperatures will reduce the available capacity
Under overcharging conditions lead acid batteries can
vent an explosive mixture of hydrogen gas. If contained,
assure adequate ventilation.
Clear the terminals before connection.
During installation all loads and chargers must be
switched off.
Use properly sized and reliable cable lugs and battery
terminals. Tighten all connections firmly.
Connect the battery with correct polarity. The
position of the battery poles may differ from previous
installed batteries!
Connect the minus cable last of all.
Use protective battery terminal insulators.
Batteries in series or parallel must be of the same brand,
type, capacity and state of charge. Do not mix old and
new batteries. See figure 1 to 4 if batteries must be
connected in parallel or in series.
Charging
Use only chargers with IUoUo characteristic.
Voltage settings: float charge 13.80V @ 77ºF / 25ºC;
absorption charge 14.25V @ 77ºF / 25ºC (max 5 hrs).
Temperature compensated charging is recommended
(
–17mV/ºF or –30mV/ºC).
Maximum charge current: 30% of rated capacity @ C10.
Incomplete charges may damage the batteries. Therefore the
batteries must be charged to the full 100% regularly, at least
every month.
Discharge
Avoid deep discharges. Regular discharges beyond 50% of
the nominal capacity are not recommended as they might
shorten the lifetime of the battery.
Recharge the battery immediately after a discharge. Never
discharge below the final discharge voltage. The final
discharge voltage is related to the discharge current. See
table
“Final discharge voltage”.
Maintenance
Check batteries and connections on a regular base, at least
every three months. Defects such as loose or corroded
connections must be corrected immediately.
Keep battery in charged condition.
Elevated environmental temperatures increase the self-
discharge rate of the batteries.
See “Battery storage”
Batteries should be recharged when the open circuit voltage
drops below 12.3 Volt.
Keep the battery dry and clean. Use only a wet soft cloth to
clean the battery. Never use any additives, acids and/or
scourers.
Do not open the battery. Never add acid or distilled water.
Disposal of batteries
Spent batteries are harmful to health and the
environment. Therefore batteries may not be
mixed with domestic or industrial waste but must
be collected and recycled separately. Contact
your supplier for recollection and recycling of
batteries or contact an authorized waste
management company.
