GB - Instructions for the use of NiMh Batteries
Important Information
Read these instructions and safety notes for your NiMH
Packs thoroughly before use
- NiMH Packs have a nominal memory effect
- NiMH Packs can only be charged with a NiMH charger
- NiMH Packs self discharge
Indemnity Statement
Jamara e.K. is not liable for any damage caused to the pro-
duct itself or through this, provided this is due to improper
operation or handling errors. The Customer alone bears the
full responsibility for the proper use and handling, including
without limitation, the assembly, the charging process, the
use and choice of the operation area. Please refer to the ope-
rating and user instructions, it contains important informati-
on and warnings.
NiHM cells should only be charged or stored on an inflammable
surface. JAMARA e.K. strongly recommend the use of either the
charger included with the model or one of its range set to the NiMH
program. Using chargers from other manufactures or incorrectly
invalidates the guarantee and JAMARA e.K. will acceptno respon-
sibility from any damage arising. Due to their high capacities da
-
maged 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
Technical 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 ad-
hered to.
Charging Temperatures:
0°C to +45°C. Charging pack outside in winter is not always
possible. 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 +40°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.
