Safety Notes:
• Do not submerge the battery in water or any other liquid.
• Do not heat or incinerate the battery, or place it in a microwave oven.
• Do not short-circuit the pack or charge it with reversed polarity.
• Do not subject the battery to physical pressure; do not deform or throw it.
• Do not solder directly to the battery.
• Do not modify or open the battery.
• Do not charge the battery to a voltage higher than 4.2 Volts per cell, or discharge it to a voltage lower than 2.5
Volts per cell.
• LiPo batteries may only be charged using a charger designed expressly for this purpose. Never connect the
battery directly to a mains PSU.
• Never charge or discharge the battery in direct sunshine, or close to a heater or fire.
• Do not use the battery in any location that is subject to severe static discharges.
• Any of these errors may cause the battery to be damaged, explode or catch fire.
• Keep the battery well out of the reach of children.
If electrolyte should escape, keep it well away from fire; the substance is highly inflammable and may burst
into flames.
• Avoid the fluid electrolyte contacting your eyes. If this should occur, rinse the affected part immediately
with plenty of clean water before seeking medical attention.
• If the fluid electrolyte should contact your clothes or any other object, wash it off immediately using plenty
of water.
• Never leave the battery on charge unsupervised.
• Charge the battery only on a fireproof surface.
To protect the environment, take defective and exhausted packs to your local free battery collection point
after ensuring that they are completely discharged. On no account, dispose of exhausted batteries in the
domestic waste. Exhausted batteries can be recycled.
Handling:
• Li-Poly cells feature an extremely low self-discharge rate of around 0.2% per day, and for this reason they can be stored
for long periods without problems. However, deep discharging must be avoided, as the pack will sustain permanent damage
in the form of loss of capacity if discharged too far (the protective electronic circuit avoids this). After about five months of
storage - but at the latest when the pack voltage falls to 2.5 Volts / cell - it is essential to recharge the pack. Before any
protracted period of storage you should recharge the battery to at least 50% of nominal capacity. After about five months the
pack should be recharged again.
• The theoretical useful life of a Lithium cell when operated at low discharge currents is around 500 charge / discharge cycles.
• Since Li-Poly cells do not suffer from the memory effect (lazy battery effect); it is not necessary to discharge them before
charging (cycling, balancing, as required with NC and NiMH batteries). In fact, it is harmful to discharge the packs first, and
this should be avoided. The capacity of Li-Poly cells declines slightly with each charge cycle, so prior discharging would
result in premature capacity loss.
