WARNING AND SAFETY NOTES
To avoid short circuit between the charge lead always connect the
charge cable to the charger first, then connect the battery. Reverse the
sequence when disconnecting.
Never attempt to charge or discharge the following types of batteries.
06
“ A battery pack which consists of different types of cells
(including different manufacturers)
“ A battery that is already fully charged or just slightly discharged.
“ Non-rechargeable batteries (Explosion hazard).
“ Batteries that require a different charge technique from NiCd,
NiMh, LiPo or Gel cell (Pb, Lead acid).
“ A faulty or damaged battery.
“ A battery fitted with an integral charge circuit or a protection
circuit.
“ Batteries installed in a device or which are electrically linked to
other components.
“ Batteries that are not expressly stated by the manufacturer to be
suitable for the currents the charger delivers during the charge
process.
WARNING AND SAFETY NOTES
Please bear in mind the following points before commencing
charging:
“ Did you select the appropriate program suitable for the type of
battery you are charging?
“ Did you set up adequate current for charging or discharging?
“
“ Have you checked the battery voltage? Lithium battery packs
can be wired in parallel and in series, i.e. a 2 cell pack can be
3.7V (in parallel) or 7.4V (in series).
“ Have you checked that all connections are firm and secure?
Make sure there are no intermittent contacts at any point in the
circuit.
