    TAKI NG CARE OF YOUR NEW BATTERY PACK

    ormally, a new battery pack comes in a very low charge condition and must be fully charged before use. Referthe user manual of your portable electronic equipment for charging instructions.

    new battery pack needs to be fully charged and fully discharged or "cycled" as much as five times tondition them into performing at full capacity.

    our equipment may report a fully charge condition in as short as 10 to 15 minutes when the new battery pack

    being charged for the first time. This is a normal phenomenon especially for Nickel Cadmium (Ni-Cad) andckel Metal Hydride (Ni-MH) chemistries. When this happens, remove the battery pack and let it cool downr about fifteen minutes then repeat the charging procedure.

    onditioning" (fully discharging and then fully charging) is necessary so as to maintain the optimumerformance of a battery pack, and is recommended at least once a month particularly for Ni-Cad and Ni-H batteries. Failure to do so could result in reduced charge capacity and can significantly shorten theattery packs useful life. Lithium Ion batteries do not require conditioning.

    is normal for a battery pack to get warm when charging and during use. However, if the battery packets excessive hot, there may be a problem with the portable electronic equipments charging circuit and

    ould therefore be checked by a qualified technician.

    echargeable batteries undergo self-discharging when left unused for long periods of time. This isormal particularly in the case of Ni-MH and Li-Ion chemistries. For best results, always store a battery packlly charged. It should be removed from the equipment and kept in a cool, dry and clean place.

    he amount of runtime a battery pack produces depends on the power requirements of components inour electronic equipment. This could be the hard drive setting, screen intensity and back-lighting onotebook computers, the liquid crystal display (LCD) screen and floodlight feature in a video camcorder, or the-mode communications network of a cellular phone. Always refer to your equipments user manual for

    ower management settings.

    BATTERY DONTS

    echargeable batt eries cont ain a considerable amount of energy.

    1. DO NOT leave on charge for extended periods.2. DO NOT short circuit terminals.3. DO NOT drop or mutilate.4. DO NOT disassemble.5. DO NOT place in fire or near sources of extreme heat.6. DO NOT expose to moisture or rain.

    BATTERY PACKS EXPLAI NED

    simplest terms, a rechargeable battery pack is a collection of one or more rechargeable cells,sembled together to provide power, measured in watts per hour (Whr), to a portable electronic device such ascamcorder or notebook computer.

    he most common forms of rechargeable cells are the Nickel Cadmium (Ni-Cad), Nickel Metal Hydride (Ni-MH)nd recently, the Lithium-ion (Li-Ion) chemistries. Each of these rechargeable technologies provides theirwn distinct advantages and disadvantages.

    DI FFERENT TYPES OF RECHARGEABLE BATTERI ES

    ckel Cadmium (Ni- Cad)

    -Cad battery is the oldest of the rechargeable chemistries used in today's portable electronic industry. Itsw cost and high discharge rate capability make it suitable for low cost electronic applications like games andys as well as for high discharge applications such as cordless power tools. Its low energy density (power--weight ratio) makes it undesirable for use in equipment such as notebooks and cellular phones. Ni-Cad haschemistry-related problem associated with it called Memory Effect, which limits the discharge capacity of the

    ll if not completely discharged during each use.

    ckel Metal Hydri de (Ni-MH)

    -MH is most commonly used in the cellular phone battery, camcorder battery, laptop battery andotebook battery. A relative of the Ni-Cad chemistry, it has improved performance in respect to the memoryfect problem, increased capacity, and therefore a higher energy density than Ni-Cad. Operation of thisemistry at elevated temperatures decreases its cycle life or the number of times a cell can be charged

    nd discharged.

    thium-ion ( Li-I on)

    he newest of the rechargeable chemistries, Li-Ion has been in mass production since 1995. With three timese voltage per cell as Nickel-based chemistries (3.6 V vs. 1.2 V), Li-Ion has a higher energy density andtherefore ideal for lightweight applications. It is currently the chemistry of choice for laptop battery,

    otebook battery, camcorder battery and cellular phone battery applications. Li-Ion battery has had a historyearly production overheating related problems and is designed in a battery pack with a Pack Controlrcuit (PCC) to protect the cells from abusive conditions such as current and voltage overcharging,gh temperature, and over-discharge. The relatively high cost of Li-Ion cells combined with the need forrcuitry makes the cost of Li-Ion battery packs higher than for other chemistries.

    MEMORY EFFECT

    -Cad batteries remember how much charge was released on previous discharges. It has a tendency tolease the same amount of energy with every charge/discharge cycle. If a Ni-Cad battery is always

    artially discharged before recharging, the usable capacity of the battery will be reduced. The Ni-MH battery isso affected by memory effect but to a lesser degree. A periodic discharge to one volt per cell or "exercise"

    essential for Ni-Cad cells to prevent the building-up of memory. "Conditioning" (fully discharging and thenlly charging) a battery pack also helps minimizing memory effect. Batteries can be fully dischargedy disconnecting the equipment from the AC power supply and letting the equipment run on battery power untilceases to function. Conditioning the battery once a month will keep it performing at its optimum level for ang time.

    THE PACK ASSEMBLY

    he cells are assembled into a battery pack configuration to provide a required amount of voltage (V) andpacity (Amperes per hour - Ah) needed to operate the equipment. The cells are connected using metalrips called tabs. The number of cells needed and the size of these cells determine the size and shape of theack. A wire lead or connector is then attached to the positive and negative terminals of the pack for connectionthe electronic device. The pack can then be wrapped in heat-shrink plastic or encased in a hard plastic enclosure.

    SMART BATTERY AND FUEL GAUGI NG

    creasingly, portable electronic equipment is becoming more complicated and power hungry. Also, usersemand to know how much battery life is remaining during the use of the equipment. This has created a needr the inclusion of complex circuitry into the design and manufacture of today's battery packs (Fuel gauging is

    ery common in the latest laptop battery, notebook battery and camcorder battery). Although it has caused

    n increase in the price of these battery packs, it has also improved the efficiency, prolonged the life andcreased their user friendliness.

    READI NG THE BATTERY SPECI FI CATI ONS

    here are two important figures to consider in reading and understanding a battery packs specifications. Firstthe voltage of the battery pack in terms of Volt or V. Second is the capacity rating in terms of Ampere-hoursh) or milliamp-hours (mAh: 1mAh=0.001Ah). The voltage of the new battery pack should always matche voltage of the original battery. The higher the Ah or mAh capacity rating of the battery pack means the

    nger runtime and does not mean incompatibilities. Most IBI battery packs have higher Ah or mAh readingsan the original, yet are manufactured up to original equipment manufacturer (OEM) standards.

    I N-FLI GHT CHARGI NG

    ore passenger airline companies are providing outlets or receptacles into which passengers can plugortable electronic equipment such as notebook computers and cellular phones for recharging during flight.

    ur industry trade associations like the Battery Association of Japan, European Portable Batteryssociation, Passenger Electronic Device Association and Portable Rechargeable Battery Association have takento account that the recharging of batteries in portable equipment while on board aircraft is notcommended. Such practice should be deferred until appropriate technical safety standards are established

    nd that such standards are fully implemented. Intelligent Batteries Inc. advocates and favors such positionnd does not recommend that any battery pack product be recharged through airline in-the-seat power sources.
