Swollen Batteries
Immediately stop using or charging. If the battery is not warm
to the touch, move it to an open safe area and observe it for at
least 15 minutes. Be VERY CAREFUL when moving the batteries.
Do NOT put ANY pressure on the batteries or covering as this
may cause fire.
Additional Information & Guidelines
1. Battery temperature the best indicator for safety. The E-flite Li-Po
Battery’s temperature should never drop below 32 degrees
Fahrenheit or go above 130 degrees Fahrenheit while charging
or discharging.
2. Changing plugs is NOT recommended as the process is
dangerous and any error can cause immediate fire. Improperly
installed plugs can also cause fire due to shorts, reverse polarity
or other improper handling which can cause battery damage.
3. Batteries should be stored in a vented, fire resistant container.
Each pack should be stored in its own locked plastic bag within
the container. The number of battery packs per container
should be extremely limited to avoid chain reactions. Storage
temperatures should not fall below 32 degrees F or above
130 degrees F. Damaged batteries must be kept at even more
ambient temperatures. High temperatures may cause fire even
with undamaged batteries.
Battery Disposal
Li-Po batteries require special handling for safe disposal. The
following are basic instructions for safe disposal. For more
detailed safety, disposal and recycling information please go to:
www.rbrc.org or www.earth911.org.
Basic Disposal Instructions
Before discarding any Li-Po battery it must be rendered safe.
The following steps must be taken to avoid damage or injury to
yourself, your property and anyone who comes in contact with
the battery.
If the battery is undamaged but no longer useful:
1. Discharge the battery to a maximum of 2.5V using a slow, safe
discharge method.
2. Leave battery uncharged and retest after at least 24 hours.
Many batteries experience “rebound” and may have more
than 2.5V after 24 hours. If the battery is over 2.5V, repeat the
procedure until the battery is 2.5V or less.
3. Insulate each wire lead with electrical tape or other
appropriate material.
4. Assure that wire leads cannot touch each other by taping them
to opposite sides of the battery.
5. Place battery in a sealed plastic bag and place plastic bag in a
vented, fire-safe container.
6. Use fire-safe container to deliver battery to a recycling center
authorized for Lithium Polymer batteries. Please note that not all
battery-recycling services include Li-Po’s. If no Li-Po recycling
facility is available in your area, contact your state or local
Hazmat agencies for instructions.
7. If the battery or wiring is damaged please contact your
state or local Hazmat facilities for instructions. Batteries must
be rendered safe before being transported or recycled. Do
NOT transport or ship batteries which have more than 2.5V
charge OR that show signs of damage without following the
instructions given by authorities. Damaged batteries should be
rendered as safe as possible and stored in a vented fireproof
container until recycled.
