Are your batteries old or refurbished? What is the meaning of "Third Party"?

Most of our batteries are brand new third party products. Brand new means new case and new cells. Third party means they are not original batteries, but we fully guarantee our batteries meet or exceed OEM specifications, since our batteries also use Grade A cells and some items have more capacity than original ones.

How to care and use battery?

Your new battery comes in a discharged condition and must be charged before use. Upon initial use (or after prolonged storage period) the battery may require two to three charge/discharge cycles before achieving maximum capacity.
If the battery is not going to be used for more than a month, it is recommended that it be removed from the device and stored in a cool, dry, clean place.
It is normal for a battery to become warm during charging and discharging.
A charged battery will eventually lose its charge if unused. It may therefore be necessary to recharge the battery after a storage period.

What should I pay attention to?

Do not short-circuit a battery. A short-circuit may cause 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 batteries to extreme heat may result in an explosion.

What is the "Memory Effect"?

Ni-Cad batteries suffer from what's called the "memory effect" This means that if a battery is continually only partially discharged before re-charging, the battery "forgets" that is has the capacity to further discharge all the way down. To illustrate: If you, on a regular basis, fully charge your battery and then use only 50% of its capacity before the next recharge, eventually the battery will become unaware of it's extra 50% capacity which has remained unused. Your battery will remain functional, but only at 50% of its original capacity. The way to avoid the dreaded "memory effect" is to fully cycle (fully charge and then fully discharge) your battery at least once every month. Batteries can be discharged by unplugging the device's AC adapter and letting the device run on the battery until it ceases to function. This will ensure your battery remains healthy. Ni-Mh and Li-Ion batteries do not suffer the memory effect.

What is a battery cycle?

Cycle life is measured by the amount of times a battery may be charged and discharged. Every time a battery is charged and discharged, it uses one cycle. Cycle life is very important in battery applications such as laptop batteries and emergency light batteries. A NiCad battery has a cycle life of 500-1000 or more cycles.

How long will the new main battery power the laptop?

Battery run-time on a laptop is difficult to determine. Actual battery running time depends upon the power demands made by the equipment. The use of the screen, the hard drive, 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 equipment. Generally, a new Hi-Capacity battery will run 30% to 50% longer than the old battery did when is was new.

How can I maximize battery performance?

Breaking In New Batteries New batteries come in a discharged condition and must be fully charged before use. It is recommended that you fully charge and discharge your new battery two to four times to allow it to reach its maximum rated capacity.
