Great Planes Triton EQ Charger - GPMM3155 User Manual

When all cycling is fi nished, “END” will show on-screen. Press BATT TYPE to see the DATA VIEW screens for all
cycling data (go to page 14). Note that TritonEQ will only show data for the last cycle (not all cycles). If set to cycle 4
times, only data for cycle 4 will be viewable (not for cycles 1, 2, or 3).

Notes for cycling NiCd and NiMH batteries:
•

Periodic cycling of NiCd batteries (once per month or two months) can be benefi cial in keeping them in good operating condition.
Excessive cycling will unnecessarily shorten the lifespan of the battery.

•

A short time delay of 3 minutes will occur in-between the charge/discharge functions to allow the battery to cool. This is normal,
and cannot be changed.

•

During cycle mode, the discharge cutoff voltage for NiCd and NiMH batteries is FIXED (not adjustable) at 0.8V per cell.

•

Cell manufacturers note three main benefi ts of cycling NiCd and NiMH batteries:

Battery maintenance: NiCd batteries benefi t the most from regular cycling to help keep them in good operating condition,
and is recommended once monthly. NiMH batteries do not require as much cycling. But excessive cycling will unnecessarily
shorten the lifespan of the battery.

Determining battery condition: NiCd and NiMH batteries are rated by how much charge energy or “capacity” they can store
compared to their rated capacity. A battery that can supply only a small fraction of its rated capacity is likely reaching the
end of its useful life and may need to be replaced.

Breaking-in batteries: new NiCd and NiMH batteries may need to be broken-in before they will perform to their specifi cations.
Older batteries which have been unused for an extended length of time may require to be broken-in again to regain their
usefulness. Repeated cycling is the best way to revive such batteries.

IMPORTANT CARE AND HANDLING FOR LITHIUM-POLYMER BATTERIES

WARNING!! NEVER ATTEMPT TO CARE FOR LITHIUM-POLYMER (LiPo) OR LITHIUM-ION (Li-Ion)
CELLS IN THE SAME WAY AS OTHER BATTERY TYPES! LiPo and Li-Ion cells are much more sensitive
and volatile than NiCd, NiMH or lead-acid batteries. Misuse and overcharge can quickly result in LiPo/Ion
cells getting hot and/or swelling, which could lead to VIOLENT EXPLOSION AND/OR FIRE and serious
personal injury and property damage.

• NEVER leave the room while charging or discharging lithium batteries!
• NEVER place lithium batteries on fl ammable surfaces during charge.
• NEVER attempt to use the NiCd, NiMH, or Pb functions with lithium batteries.
•

NEVER continue to charge or use LiPo/Ion cells if they start to swell, become overly warm to the touch, or if they do
not charge within the specifi ed charging time. Failure to follow this guideline could cause the battery to become hot,
and explode or ignite!!

• NEVER discharge Li-Ion cells lower than 2.5V per cell.
• ALWAYS have a “class D” fi re extinguisher available when handling LiPo batteries.
• LiPo/Ion cells hold charge very well, and should not be trickle charged or cycled.
• LiPo/Ion cells should be charged about once per year at a minimum to prevent over-discharge.
• LiPo/Ion batteries should be stored with about 30%-50% of capacity.
• If LiPo/Ion cells leak fl uid, rinse the affected area well with water and seek immediate medical care.
