Laptop Battery FAQ(1)

Q: I just received my new battery charger - Why does it not charge my battery?

    A:Our battery charger has very few problems because of its high quality standard. First, our battery charger is wall and car charger 2 in 1. The AC plug is folded on the back of charger body, unfold it then you can put the charger into AC wall outlet. The charger's LED will keep green if your battery pins don't touch the charger prongs, you must seat the battery well in your charger to make the battery locked. Sometimes you might need to shove the battery a little hard to snap it into the charger. The charger's LED stays on red while the battery is charging and it turns green after the battery is fully charged. New battery sometimes is difficult to hold the charge, and you probably see the charger's LED is green but the battery is not charging (battery and charger are not warming up) at all. To solve it, while keep your charger AC power on, please take the battery out and re-insert it into the charger several times to activate dormant cells to start holding charge. This will make LED turn red and the charger begins to charge the battery.

Q:Your replacement battery's voltage is slightly different from my original battery's, does it damage my device?

    A:Minor voltage discrepancy is reasonable and acceptable for replacement batteries. Some camera camcorder batteries have 0.2V difference from original ones, and some laptop batteries have 0.4V difference. This won't damage your device nor affect battery's performance.

Q:What's the deal with each type of rechargeable battery?

  A:Nickel Cadmium is the most popular type of rechargeable battery, although it tends to suffer from 'memory effect'. It has a high rate of energy discharge, meaning that it is low maintenance with high performance. Nickel Cadmium can deliver even power until nearly all of the battery has been used.

Q:Nickel Metal Hydride is the most advanced commercial rechargeable battery. Nickel Metal Hydride batteries last 40% longer than Nickel Cadmium batteries. This battery is generally much more environmentally friendly than Nickel Cadmium, as well.

   A:Lithium Ion batteries do not suffer from the “memory effect” at all. These batteries have twice the energy of Nickel Metal Hydride, although they weigh 33% less. This is especially nice for portable items, such as laptops, digital cameras and camcorders.

 Q:What is the Memory Effect?

   A:NiCad batteries, and to a lesser extent NiMH batteries, suffer from what's called the "memory effect". What this means is that if a battery is repeatedly only partially discharged before recharging, the battery "forgets" that it 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 its extra 50% capacity which has remained unused. The 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) the battery at least once every two to three weeks. 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 insure your battery remains healthy.

 Q:Can I upgrade my current battery to a newer chemistry?

    A:NiCad, NiMH and Lithium Ion are all fundamentally different from one another and cannot be substituted unless the device has been pre-configured from the factory to accept more than one type of rechargeable battery technology. The difference between them stems from the fact that each type requires a different charging pattern to be properly recharged. Therefore, the portable device's internal charger must be properly configured to handle a given type of rechargeable battery. Refer to your owner's manual to find out which rechargeable battery types your particular device supports.
