Muchmore LiPo Batteries - Manual (Page 4)

• NEVER allow LiPo batteries to be charged or discharged on
or near combustible materials, including paper, plastic,
carpets, vinyl, leather, wood, inside an R/C model or full-
sized automobile!
• NEVER put loose cells or packs in the pocket of any
clothing!
• NEVER allow LiPo cells to come in contact with moisture or
water at any time.
• NEVER store batteries near an open flame or heater.
• NEVER assemble LiPo cells or pre-assembled packs together
with other LiPo cells/packs. Only a qualified battery assembly
company should assemble or modify LiPo batteries.
• NEVER allow LiPo cells to become punctured, especially by
metallic objects such as screwdrivers, T-pins, or hobby knives.
• NEVER charge or discharge a LiPo battery without having
an “ABC type” lithium approved fire extinguisher readily
available in case of a fire.
• DO NOT allow the battery’s internal electrolyte to get in the
eyes or on skin. Wash affected areas with soap and water
immediately if they come in contact with the electrolyte. If
electrolyte makes contact with the eyes, flush with large
amounts of water for 15 minutes and seek medical attention
immediately! If a battery leaks electrolyte or gas vapors, do
not inhale leaked material. Leave the area and allow the
batteries to cool and the vapors to dissipate. Remove
spilled liquid with absorbent and dispose.
• ALWAYS provide adequate ventilation around LiPo
batteries during charge, discharge, and during storage. If a
battery becomes overheated IMMEDIATELY place it in a
fire-proof location until it cools.
• ALWAYS store LiPo cells/packs in a secure location away
from children.
• ALWAYS make sure that metallic objects, such as
wristwatches, bracelets, or rings are removed from your
hands when handling LiPo packs. Accidentally touching
battery terminals to any such objects could create a short-
circuit condition and possibly cause severe personal injury.
Unlike NiCd batteries, lithium-polymer batteries are
environmentally friendly. For safety reasons, it’s best that
LiPo cells be fully discharged before disposal (however, if
physically damaged it is NOT recommended to discharge
LiPo cells before disposal - see below for details). The
batteries must also be cool before proceeding with disposal
instructions. To dispose of LiPo cells and packs:
1. If any LiPo cell in the pack has been physically damaged,
resulting in a swollen cell or a split or tear in a cell’s foil
covering, do NOT discharge the battery. Jump to step 5.
2. Place the LiPo battery in a fireproof container or bucket
of sand.
3. Connect the battery to a LiPo discharger. Set the discharge
cutoff voltage to the lowest possible value. Set the discharge
current to a C/10 value, with “C” being the capacity rating of
the pack. For example, the “1C” rating for a 1200mAh battery
is 1.2A, and that battery’s C/10 current value is (1.2A / 10)
0.12A or 120mA. Or, a simple resistive type of discharge load
can be used, such as a power resistor or set of light bulbs as
long as the discharge current doesn’t exceed the C/10
value and cause an overheating condition. For LiPo packs
rated at 7.4V and 11.1V, connect a 150 ohm resistor with a
power rating of 2 watts (commonly found at Radio Shack) to
the pack’s positive and negative terminals to safely discharge
the battery. It’s also possible to discharge the battery by
connecting it to an ESC/motor system and allowing the motor
to run indefinitely until no power remains to further cause the
system to function.
4. Discharge the battery until its voltage reaches 1.0V per cell
or lower. For resistive load type discharges, discharge the
battery for up to 24 hours.
5. Submerse the battery into bucket or tub of salt water. This
container should have a lid, but it does not need to be air-
tight. Prepare a bucket or tub containing 3 to 5 gallons of cold
water, and mix in 1/2 cup of salt per gallon of water. Drop the
battery into the salt water. Allow the battery to remain in the
tub of salt water for at least 2 weeks.
6. Remove the LiPo battery from the salt water and place it in
the normal trash.
