WARNING: Burn hazard. Battery liquid may be flammable if exposed to spark or flame.
WARNING: Fire hazard. Never attempt to open the battery pack for any reason. If the battery
pack case is cracked or damaged, do not insert into the charger. Do not crush, drop or damage the
battery pack. Do not use a battery pack or charger that has received a sharp blow, been dropped,
run over or damaged in any way (e.g., pierced with a nail, hit with
a hammer, stepped on). Damaged battery packs should be returned to the service center for
recycling.
Storage Recommendations
1.The best storage place is one that is cool and dry, away from direct sunlight and excess heat or
cold.
2.For long storage, it is recommended to store a fully charged battery pack in a cool dry place out of
the charger for optimal results.
NOTE: Battery packs should not be stored completely depleted of charge. The battery pack will
need to be recharged before use
Transportation
WARNING: Fire hazard. Do not store or carry the battery pack so that metal objects can
contact exposed battery terminals. For example, do not place the battery pack in aprons, pockets,
tool boxes, product kit boxes, drawers, etc., with loose nails, screws, keys, etc. Transporting
batteries can possibly cause fires if the battery terminals inadvertently come in contact with
conductive materials such as keys, coins, hand tools and the like. The US Department of
Transportation Hazardous Material Regulations (HMR) actually prohibit transporting batteries in
commerce or on airplanes in carry-on baggage UNLESS they are properly protected from short
circuits. So when transporting individual battery packs, make sure that the battery terminals are
protected and well insulated from materials that could contact them and cause a short circuit.
Important Safety Instructions for All Battery Chargers
WARNING: Read all safety warnings, instructions, and cautionary markings for the battery
pack, charger and product. Failure to follow the warnings and instructions may result in electric
shock, fire and/or serious injury.
•DO NOT attempt to charge the battery pack with any chargers other than a YEEFERM charger.
YEEFERM charger and battery pack are specifically designed to work together.
•These chargers are not intended for any uses other than charging YEEFERM rechargeable
batteries. Any other uses may result in risk of fire, electric shock or electrocution.
•Do not expose the charger to rain or snow.
•Pull by the plug rather than the cord when disconnecting the charger. This will reduce the risk of
damage to the electric plug and cord.
•Make sure that the cord is located so that it will not be stepped on, tripped over or otherwise
subjected to damage or stress.
•Do not use an extension cord unless it is absolutely necessary. Use of improper extension cord
could result in risk of fire, electric shock or electrocution.
