NEVER LEAVE A BATTERY CHARGING UNATTENDED
LITHIUM ION BATTERIES
WARNING: LI-ION CELLS HAVE INHERENT RISKS. IF MISUSED OR MISHANDLED, CELL CAN EXPLODE CAUSING SEVERE BURN INJURY, FATALITY, and PROPERTY DAMAGE.
READ BELOW THOROUGHLY –
- KEEP OUT OF REACH of minors (at least 18 years of age) and pets.
- DO NOT PUT IN FIRE, oven, microwave, or expose to anything over 100oC (212oF)
- DO NOT CARRY or store OUTSIDE of its protective packaging or a PROTECTIVE CELL CASE. The protective cell case must PREVENT CELLS FROM TOUCHING ONE ANOTHER. UNDER NO CIRCUMSTANCE is a protective case to be put in a pocket, bag, purse, or on your body. A protective case can be carried by hand in a controlled manner and/or stored where it is not subjected to movement or extreme temperatures.
- DO NOT PUT IN POCKET, bag, purse, or on your body (applicable at all times and in all circumstances). Pockets contain KEYS, COINS, OBJECTS, and/or DEBRIS that can short-circuit a cell (battery) that can result in an explosion. The cell is to be stored in its protective packaging or a protective case that prevents cells from touching one another. UNDER NO CIRCUMSTANCE ARE CELLS (batteries) TO BE PUT IN A POCKET, bag, purse, or on your body. With cell(s) in a protective case, carry by hand or store where cell(s) are not subjected to movement.
- DO NOT PUT A DEVICE WITH CELL(S) INSTALLED IN IT IN YOUR POCKET or ON YOUR BODY. As unlikely as it may be, a device can malfunction and/or be affected by debris or object(s) in the pocket that can short-circuit a cell causing it to explode. Additionally, removable-battery devices enable the cell(s) to move/shift inside a device which can subject cell(s) to condition(s) that put wear and tear on a cell’s protective label/wrap/skin barrier. This can lead to a short-circuit and potential explosion. Being in a pocket subjects the device (and cell(s)) to abrupt and jarring movements. Carrying and using the device with hand(s) is proper. ** Hohm Tech encourages to use a fire-retardant case/enclosure to carry device(s) with cell(s) installed inside it (applicable to device(s) with external and/or removable cell(s)).
- DO NOT USE IN A DEVICE THAT CAN EXCEED MAX CELL WATTAGE (W) or AMPERAGE (A) (listed on each cell and retail packaging). Otherwise, this can overload a cell, causing it to explode.
- DO NOT USE A LOWER RESISTANCE (Ω) # (listed on each cell and retail packaging). Otherwise, this can overload cell, causing it to explode.
- DO NOT USE CELL WITH ANY DAMAGE TO ITS STRUCTURE OR OUTER PROTECTIVE LABEL (also called “WRAP”, “sleeve”, “skin”). Damage may include: dent(s), tear(s), nick(s), puncture(s), corrosion, or any other undisclosed abnormalities or damages. Otherwise, a cell can short-circuit and explode. ALWAYS INSPECT cell VISUALLY and by TOUCH to SEE/FEEL for damage BEFORE EACH USE. ** SEE THE ILLUSTRATION BELOW AS A GUIDELINE. **
- DO NOT LEAVE UNATTENDED WHILE CHARGING, & IMMEDIATELY REMOVE CELL(s) FROM CHARGER ONCE FULLY CHARGED to ensure it is not exposed to any potential charger malfunction such as overcharging which could damage the cell causing it to explode.
- DO NOT CHARGE HIGHER THAN MAX CHARGE VOLTAGE (V) (typically 4.2V) or DISCHARGE BELOW MAX VOLTAGE CUT-OFF (V) (typically 2.5V). Overcharging or over-discharging cell(s) can cause irreversible damage and cause it to explode.
- DO NOT MIX WITH USED or DIFFERENT BATTERY TYPES. Differences in cell capacity can lead to one or more cell(s) being overcharged or over-discharged.
- IF USING A MULTI-CELL DEVICE, the device MUST HAVE A NON-CONDUCTIVE BARRIER (typically plastic) OR FITMENT that PREVENTS CELL(S) from TOUCHING THE SIDE(S) OF ONE ANOTHER OR ANY ADJACENT METAL except for the very center of top and bottom of the cell. Otherwise, cell(s) could short-circuit and explode.
- ALWAYS REPLACE CELL when capacity has decreased or within a maximum of 12 months of use (whichever occurs first) when used in a device that allows cell(s) to be changed/removed. Cell degradation and wear incurred from repeated installation/removal can negatively impact cell integrity and subject it to conditions that can cause it to be short-circuited and explode.
- ALWAYS charge, connect, and operate cell(s) within their capabilities as listed on each cell, packaging, and all product detail pages, while adhering to the device’s user manual.
- COMPLETELY READ and follow the WARNING section listed on each cell, packaging, and here, in its entirety.
- NEVER store an uncovered battery in your pocket, purse, or anywhere it may come into contact with metal (loose change, keys...)
- Disconnect battery when not in use
- Use battery only for its intended use - Never use a battery in an appliance it is not intended for
- Do not leave battery on charger once it is fully charged
- Never disassemble, modify, or solder a battery
- Do not place battery in fire or water
- Never charge with an unspecified or modified charger (Do not use a charger that has a mAh rating higher than the total battery capacity)
- Never charge a battery that has been damaged
- Maintain your battery and charger - make sure the connections are clear and clean
- Dispose of battery properly
General information regarding Lithium-ion Batteries
Lithium-ion batteries are common in consumer electronics. They are one of the most popular types of rechargeable battery for portable electronics, with one of the best energy densities. [Source: http://en.wikipedia.org/wiki/Lithium-ion_battery]
SAFETY HAZARDS of BATTERIES
Battery technology is at the heart of much of our technological revolution. One of the most prevalent rechargeable batteries in use today is the lithium-ion battery. Cell phones, laptop computers, GPS systems, iPods, and even cars are now using lithium-ion rechargeable battery technology. In fact, you probably have a lithium-ion battery in your pocket or purse right now!
Although lithium-ion batteries are very common there are some inherent dangers when using ANY battery. Lithium cells are like any other technology–if they are abused and not used for their intended purpose catastrophic results may occur, such as: first, second, and third-degree burns, respiratory problems, fires, explosions, and even death.
Please handle lithium-ion batteries with care and respect.
User Safety Precautions
- When the battery is not in use, you MUST disconnect the battery from the battery connector. When the battery is connected to the battery connector, do not leave unattended since the two wires with the alligator clips can touch which will heat up the battery. Short-circuiting will damage the battery and generate heat that can cause burns. [E-CIGARETTE Note: Does not apply to e-cigarettes. Do not attempt to charge an e-cig with alligator clips.]
[E-CIGARETTE NOTE: CHARGE BATTERY ONLY. Do not leave other devices attached. Example: Remove Clearomizer from Battery when charging through a USB Pass-through.]
- Don’t leave the battery in the charger once it is fully charged. The battery charger will flash on and off with a red indicator light every 20 seconds when the battery is fully charged. Overcharging the batteries will not increase the performance and could lead to damage.
- [E-CIGARETTE NOTE: Once battery is charged, the indicator light will be solid green. Red means it is charging.]
Disassembly [or Modifying a Battery]
- Never disassemble a battery as the materials inside may be toxic and may damage skin and clothes. [E-CIGARETTE NOTE: Never modify an E-cigarette battery]
- DO NOT place a battery in fire; this may cause the battery to rupture.The electrolyte is very flammable and if an ignition source exists, then fire and even an explosion could result.
- NEVER place batteries in water, as this may cause the battery to rupture and release poisonous gasses. Furthermore, when the electrolyte is combined with water, there is the potential for hydrofluoric acid to form–an extremely toxic and corrosive substance. (To learn more about hydrofluoric acid, visit the following link to the Centers for Disease Control’s website: http://www.bt.cdc.gov/agent/hydrofluoricacid/basics/facts.asp)
- Never solder anything directly to a battery. This can destroy the safety features of the battery by damaging the safety vent inside the cap.
- Never charge with an unspecified charger or specified charger that has been modified. This can cause breakdown of the battery or swelling and rupturing.
- Never attempt to charge a battery which has been physically damaged.
- Avoid designing airtight battery compartments. In some cases, gases(oxygen, hydrogen) may be given off, and there is a danger of a battery bursting or rupturing if ignited by sparks.
- Do not use a battery in an appliance or purpose for which it was not intended. [E-CIGARETTE NOTE: Do not use a charger that has an mAh rating higher than the total battery capacity. Example: Never use an eGo 420 mAh charger with a 280 mAh pen-style battery.]
- If the foil packaging on the battery does break, vent the room and leave area.
- If a fire starts, call the fire department immediately. The only extinguisher that will work on a Lithium-ion Battery fire is a Class D Fire Extinguisher or Dry Sand or Dry Table Salt.
Lithium-ion batteries are found in many electronics like laptops, digital cameras, power tools, and cordless phones [and Electronic Cigarettes]. These batteries are very popular because they can be recharged and because they are able to supply power for a long period of time. However, even lithium-ion batteries reach a point where they can no longer hold a charge and need to be disposed of. When this time comes, it is important to know how to recycle the battery, and not simply put it in a trash can. Determine your states recycling policy.
There are many reasons to recycle these batteries rather than throw them away where they may end up in a regular landfill. This is because they enter the solid waste stream and can contaminate soil and water. Please check with your [city or state] on their policy of recycling of batteries.
