Indemnity Statement
JAMARA e.K. accept no responsibility for any damage caused
by its products which arises through misuse. The customer
alone bares the responsibility for the use andoperation of this
product and this includes, for example, the method of chan-
ging and application for which the packs are used. If you are
not in agreement with the above conditions you may return
this product unused to your dealer within 14 days.
NiHM cells should only be charged or stored on an inflammable sur-
face. JAMARA e.K. strongly recommend the use of either the charger
included with the model or one of its range set to the NiMH pro-
gram. Using chargers from other manufactures or incorrectly inva-
lidates the guarantee and JAMARA e.K. will acceptno responsibility
from any damage arising. Due to their high capacities damaged or
incorrectly treated packs can ignite and to this end any charging or
discharging of packs must be monitored.
After a crash the packs must be thoroughly inspected for damage
and you should never attempt to charge or discharge a damaged
pack.
If a cell is damaged, it is possible that it may short-circuit and ignite
for up to 30 minutes after the impact and for this reason packs must
be placed on a fire proof surface and observed for half an hour after
any impact. Burning cells or packs must be extinguished with sand
or powder.
Safety Policy
JAMARA accepts no responsibility for any damage caused by or to
its products which is caused by failing to follows these instructions.
- The incorrect use of these cells can lead to an explosion and or
fire! Risk of injury!
- Over-charging, the use of too high currents, or deep discharging
may damage the cells
- Protect from mechanical damage (crushing, dents, bending or
piercing)
- Never attempt to open the cells, never expose them to fire and
keep them away from children
- Always treat damaged or leaking cells with the utmost caution
as they may cause injury
- Never short-circuit cells and observe the correct polarity
- Protect cells from temperatures of over 65°C, do not mount them
near to heat sources, i.e. Exhausts
- Store packs (over winter) half full. Do not store them empty or full
- Periodically check the state of charge of packs stored for long
periods
- The contents of the cells is will cause injury to skin and eyes
- In the event of skin contact, wash the area thoroughly with
plenty of water and remove any clothing
- In the event of eye contact, wash thoroughly with plenty of
water and consult a doctor

echnical Details
Over-Charging:
If the charger fails to switch off due to a technical defect the cells
may overheat and ignite, for this reason, charging must always be
monitored
Fast Charging:
Fast charging is possible. The maximal rated current must be adhe-
red to.
Charging Temperatures:
0°C to +45°C. Charging pack outside in winter is not always possi-
ble. The cell temperature must not exceed 65°C. To monitor this we
recommend using our JAMARA Thermo Scan 300 (contact less infer
red thermometer) Part No. 17 0133.
Discharging Temperatures:
-20°C to +60°C. This make flying in winter possible, however, minus
temperatures can lead to a 20% reduction in capacity and reduced
current draw.
Life Span:
Heavily dependant on use.
