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. Donot store or carry the battery pack sothat 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 ifthe battery terminals inadvertently come in contact with conductive materials such as
keys, coins, hand tools and the like. The US Department ofTransportation Hazardous Material
Regulations (HMR) actually prohibit transporting batteries incommerce or on airplanes in carry-on
baggage UNLESS they are properly protected from short circuits. Sowhen 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 inelectric shock, fire
and/or serious injury.
•DO NOT attempt tocharge the battery pack with any chargers other than a YEEFERM charger.
YEEFERM charger and battery packare specifically designed to work together.
•These chargers are not intended for any uses other than charging YEEFERM rechargeable batteries.
Any other uses may result inrisk offire, 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 itwill not be stepped on, tripped over or otherwise subjected
to damage or stress.
•Do not usean extension cord unless itisabsolutely necessary. Use of improper extension cord could
result in risk of fire, electric shock or electrocution.
•When operating a charger outdoors, always provide a dry location and use an extension cord suitable
for outdoor use. Use of acord suitable for outdoor use reduces the risk of electric shock.
•An extension cord must have adequate wire size (AWG or American Wire Gauge) for safety. The
smaller the gauge number of the wire, the greater the capacity ofthe cable, that is, 16 gauge has more
capacity than 18 gauge. An undersized cord will cause a drop in line voltage resulting in loss of power
and overheating. When using more than one extension to make up the total length, be sure each
individual extension contains at least the minimum wire size. The following table shows the correct size
to use depending on cord length and nameplate ampere rating. If in doubt, use the next heavier gauge.



The lower the gauge number, the heavier the cord.
Do not place any object on top of the charger or place the charger on a soft surface that might block the
ventilation slots and result in excessive internal heat. Place the charger in a position away from any
heat source. The charger is ventilated through slots in the top and the bottom of the housing.
•Do not operate the charger with a damaged cord or plug.
•Do not operate the charger ifit has received a sharp blow, been dropped or otherwise damaged in any
way. Take ittoan authorized service center.
•Do not disassemble the charger; take it to an authorized service center when service or repair is
required. Incorrect reassembly may result in a risk ofelectric shock, electrocution or fire.
•Disconnect the charger from the outlet before attempting any cleaning. This will reduce the risk of
electric shock. Removing the battery packwill not reduce this risk.
•NEVER attempt to connect 2 chargers together.
•The charger isdesigned to operate on standard 120V household electrical power. Do not attempt to
use it on any other voltage. This does not applytothe vehicular charger.
WARNING: Shock hazard. Do not allow any liquid to get inside the charger. Electric shock may
result.
WARNING: Burn hazard. Donot submerge the battery packin any liquid or allow any liquid to
enter the battery pack. Never attempt to open the battery packfor any reason. If the plastic housing of
the battery pack breaks or cracks, return to a service center for recycling.
CAUTION: Burn hazard. To reduce the risk of injury, charge only YEEFERM rechargeable battery
packs. Other types of batteries may overheat and burst resulting in personal injury and property
damage.
