The number of counterfeit batteries sold by street vendors or on the Internet is growing. For instance, batteries labelled as Li-ion actually contain cheaper nickel-based cells. Genuine Li-ion batteries include a safety circuit to cut off power when reaching full charge. Most counterfeit batteries do not include this safety feature. The result: The battery overheats to the point of melting the phone’s casing and sometimes destroying the phone’s internal circuits.
Certain cases of explosion from mobile phones have been reported. Most of them have been linked to cheaper, nonmanufacturer-approved or counterfeit batteries.
It’s too risky to purchase third-party batteries from street vendors. Replace your battery with original or well-known manufacturer-approved brands.
In some phones, the battery is permanently attached to the back lid. So to get a replacement battery, you have to basically buy the back lid. These batteries are usually the Li-ion polymer type. Such a design offers good protection against counterfeit batteries, since it is costlier and more difficult to manufacture these batteries.
Some Battery Myths and Truths:
- Higher the rating, longer the talk time
This is true with batteries of the same type for the same phone. For instance, a 720 mAh rating NiMH battery gives you more talk time than a 600 mAh NiMH battery. This may not be true, however, when comparing batteries of different types. For instance, a 720 mAh rating NiMH battery may not necessarily give you more talk time than a 600 mAh Li-ion battery.
Be careful when comparing battery performance between phones because talk time can vary with the type of the phone, geography, and signal strength.
- Battery comes with warranty like phone
False. Although handsets routinely come with a one-year warranty, most manufacturers provide only a six-month warranty for batteries. Some do not provide any warranty for any accessories — including batteries.
- Do not charge your phone every day
False. The myth was based on the theory that charging every day will shorten the lifetime of batteries since most batteries have a certain number of cycle years. This is not true with the popular Li-ion or Li-polymer batteries since they last for a fixed number of years — whether used or not.
- Keep unused batteries in the fridge
True. Keeping them in cooler temperatures will prolong their life, just as keeping them exposed to heat will reduce their life. However, do not keep them in the freezer because some batteries can become damaged at subzero temperatures.
- Always purchase two batteries, one for backup
False. We know that Li-ion and Li-polymer batteries start aging from the date of manufacture. There’s no point in buying both batteries at the same time since both of them have roughly the same expiry dates. (Buy the backup at a later date or, in case you already bought a spare at the same time, keep it in the fridge.)
- Charge your battery for the full 12 hours the first time
True. A second full 12-hour charge is also recommended to ensure the series of cells that make up the battery are all fully charged.
7 Any type of battery will be all right for your phone
True — as long it fits your phone. Your phone may come with a standard 720 mAh NiMH battery, but you can always purchase a 900 mAh Li-ion battery — provided it is made for the same phone.
