What is "memory effect"?

A partially discharged battery at times does not fully discharges before recharging. It sort of "forgets" to do so. This is what is the memory effect. For e.g. if you fully charge your battery and then use only 50% of its capacity before the next recharge, eventually the battery will become unaware of its extra 50% capacity, which has remained unused. The battery will remain functional, but only at 50% of its original capacity. To deal with this, always fully discharge your battery, before recharging it. This can be done by, unplugging the device's AC adapter and letting the device run on the battery until it ceases to function. This will help your battery remain healthy. 
What Are Volts and Milliamp-hours (mAH)? 
These are ratings on every battery. Milliamp-hours or (mAH), is one-thousandth of an amp-hour (1AH = 1000mAH). The voltage of the new battery should always match the voltage of your original unless the batteries are different chemistries. NiMH and Li-Ion batteries have different voltage ratings, even if they're for the same device. 
How long do typical batteries last? 
Generally, 11/2 - 3 years, or 500-800 charge-discharge cycles. As the rechargeable battery begins to die, there is a decline in the running time of the battery, till it reaches to 50% of its running time, and you need a new battery. 
Can I recycle my old battery? 
NiCad, NiMH and Li-Ion batteries should be recycled. Be environmentally conscious - do NOT throw these batteries in the trash. 
How long will my new battery run? 
Battery run-time is difficult to determine. Actual battery running time depends upon the power demands made by the mobile phone. The use of the screen, the device and other accessories results in an additional drain upon the battery, effectively reducing its running time. The total run-time of the battery is also dependent upon the design of the mobile phone.

Battery Do's:

Fully charge/discharge battery up to 4 cycles before achieving full capacity of a new battery 
Fully discharge and then fully charge the battery every two to three weeks. 
Run the device under the battery's power until it shuts down or until you get a low battery warning. Then recharge the battery as instructed in the user's manual. 

Remove from the device and store in a cool, dry, clean place if the battery will not be in use for a month or longer. 
Recharge the battery after a storage period Ensure maximum performance of the battery by optimizing the device's power management features. Refer to the manual for further instructions.


Battery Don'ts: Do not short-circuit. A short-circuit may cause severe damage to the battery. 

Do not drop, hit or otherwise abuse the battery as this may result in the exposure of the cell contents, which are corrosive. 

Do not expose the battery to moisture or rain. 

Keep battery away from fire or other sources of extreme heat. Do not incinerate. Exposure of battery to extreme heat may result in an explosion 


Tip: 
Turn off the phone, take out the battery and put it in again. Rest batteries for 24 hours before charging. It is known that generally even when your phone is "sleeping", it is not. 
Protect your phone against thefts: 
The International Mobile Equipment Identity umber (IMEI) (a 15 digit code) is programmed in the phone at the time of manufacture. This will help the police track down the phone if it is stolen. To know this number: 1. Type *#06# on the mobile. 2. A number appears. 3. Confirm this with the number on the battery. If this does not match then it means that the phone has been tampered with or is refurbished. 4. Note the number in a safe place.
