Please keep in mind the following points when designing and manufacturing equipment. Please insert
in your instruction manual. To prevent equipment malfunctions from affecting the batteries, be sure to
use protection devices for electrical circuits and batteries.
Danger!
Failure to carefully observe the following procedures and precautions can result in leakage of battery
fluid(electrolyte), heat generation, explosion, fire and serious personal injury!
•Never dispose of HFR batteries in a fire or heat them.
•Do not connect the (+) positive and (-) negative terminals of HFR batteries together with electrically
conductive materials, including lead wires. Do not transport or store HFR batteries with their
uncovered terminals or connected with a metal necklace or other electrically conductive material.
When carrying or storing batteries, use a special case.
•Only charge HFR batteries using those specific chargers that satisfy Highpower’s specifications. Only
charge batteries under the conditions specified by Highpower.
•Never disassemble HFR batteries. Doing so may cause an internal or external short circuit or result in
exposed material of battery reacting chemically with the air. It may also cause heat generation,
explosion and fire. Also, this is dangerous as it may cause splashing of alkaline fluid.
•Never solder lead wires directly on to HFR batteries
•The (+) positive and (-) negative terminals of HFR batteries are predetermined. Do not force the
terminals to connect to a charger or equipment. If the terminals can not be easily connected to the
charger or the equipment, check if the (+) and (-) terminals are incorrectly positioned.
•The gas release vent which release internal gas is located in the (+) positive terminal of the HFR
battery. For this reason, never deform his section or cover or obstruct its gas release structure
•Do not directly connect HFR batteries to a direct power source or the cigarette lighter socket in a car.
•Do not use HFR batteries in any equipment other than those specified by Highpower.
•HFR batteries contain a strong colorless alkaline solution(electrolyte). The alkaline solution is
extremely corrosive and will cause skin damage. If any fluid from a HFR battery comes in contact with
user’s eyes, they should immediately flush their eyes and wash them thoroughly with clean water from
the tap or another source and consult a doctor urgently. The strong alkaline solution can damage eyes
and lead to permanent loss of eyesight.
•When HFR batteries are to be incorporated in equipment or housed within a case, avoid air-tight
structures, as this may lead to the equipment or the case being damaged or may be harmful to users.
Warning!
•Do not apply water, seawater or other oxidizing reagents to HFR batteries, as this can cause rust and
heat generation. If a battery becomes rusted, the gas release vent may no longer operate, and can result
in explosion.
•Do not over-charge HFR batteries by exceeding the predetermined charging period specified by the
battery charger’s instructions or indicator. If HFR batteries are not fully charged after the battery
charger’s predetermined charging period has clasped, stop the charging process. Prolonged charging
may cause leakage of battery fluid, heat generation, and explosion. Be sure to handle recharged
batteries carefully as they may be not.
•HFR batteries contain a strong colorless alkaline solution (electrolyte).If the skin or clothing comes in
contact with fluid from a HFR battery; thoroughly wash the area immediately with clean water from the
tap or another source. Battery fluid can irritate the skin.
•Do not connect more than 21 HFR batteries in series, as this may cause electrical shocks, leakage of
battery fluid and heat generation
•Do not remove the outer tube from a battery or damage it. Doing so will expose the battery to the risk
of a short circuit, and may cause leakage of battery fluid, heat, generation, explosion and fire
•If HFR batteries leak fluid, change color, change shape, or change in any other way, do not use them,
otherwise they may cause heat generation, explosion and fire.
•Keep HFR batteries and the equipment using them out of the reach of babies and small children, in
order to avoid accidental swallowing of the batteries. In the event the batteries are swallowed, consult a
doctor immediately.
•When the operating time of a HFR battery becomes much shorter than its initial operating time even
after recharged, it should be replaced to a new battery as its battery life has ended
CAUTION!
•Do not strike or drop HFR batteries.
•Store HFR batteries out of the reach of babies and small children. When charging or using a battery,
do not let babies or small children remove the battery from the charger or the equipment being used.
•Be sure to charge HFR batteries within a temperature range of 0 to 40 deg C (degrees Celsius)
•Be sure to use the recommended charging method for HFR batteries read the battery charger’s
instruction manual carefully
•Do not use or store battery at high temperature, such as in strong direct sunlight, in cars during hot
weather, or directly in front of a heater. This may cause leakage of battery fluid. It could also impair
performance and shorten operating life of HFR batteries
•Be sure to turn off the equipment after use of HFR batteries, otherwise may result in leakage of battery
fluid
•After removed from equipment, store HFR batteries in a dry place and within the recommended
storage temperature range. This will help preserve the batteries’ performance and durability and
minimize the possibility of leakage of battery fluid or corrosion.(Highpower recommends the storage
temperature range from -20 to +30deg.(for longer service life).
•To use batteries for the first time after purchase or having not used them for a long period of time, be
sure to charge them.
•After long term storage, there is a possibility that the battery could not be fully charged. In order to
fully charge it, please charge and discharge battery for a few times.
•Do not use old and new batteries mixed together, or batteries at different charge levels. Do not use the
HFR battery mixed with a dry cell or other batteries of different capacity, type, or brand name. This
may cause leakage of battery fluid and heat generation.
•If the HFR battery terminals become dirty, clean up them with a soft dry cloth prior to use. Dirt on the
terminals can result in poor contact with the equipment, loss of power, or inability to charge.
WARRANTY
Highpower will be responsible for replacing the batter against any defects or poor workmanship for six
months from the date of shipping.
Any other problems caused by malfunction of the equipment or misuse of the battery are not under this
warranty.
SAFETY
To assure safety, please consult to the Highpower technical staff for your applications including
electrical specifications, mechanical designs, protective devices and any special specification.
