Problem with Nickel-Metal Hydride (NiMH)



Mobile phone batteries come in different types, and with each of those types different challenges must be overcome in order to take full advantage of the battery's capabilities and life span.

Understanding memory effect, battery conditioning and each battery's capabilities and other drawbacks will allow you to make an educated decision when picking out a cell phone battery.

NiMH batteries are prone to a phenomenon known as "memory effect" in which they must be fully discharged in other words battery should be empty before recharging

If users recharge the batteries when they are less than empty, the battery will think the remaining amount of battery is no longer available and the battery will no longer charge fully in the future.

These batteries are also more prone to overheating and are made from toxic materials.

When using a battery that is prone to the memory effect (NiMH and NiCD) users should condition the battery. This is accomplished by fully charging the battery for 24 hours and then allowing the battery to fully drain.

Repeat the 24-hour recharge and drain method three to five times in a row. After each 10th charge, repeat the battery drain and 24-hour charge one time.
