ADing PowerAlarm allows laptop computer owners to keep track of how much life (power) remains in the battery currently being used. In this way it lets you see early when you will have to shut down your work, because it continuously displays status icons so that you can always tell if your battery is low. Features: * battery life as a percentage * visual variable battery power icon and chart * sound effects on discharging Why to use ADing PowerAlarm? The battery type used in most notebooks, the nickel-cadmium (NiCd) type, has a mediocre capacity (stored energy) who decline significantly if the battery is not discharged completely (memory effect). Your battery remembers that it has not been used to its full potential and will recharge only to about the capacity needed last. The next time you want high performance your battery will fail to meet the expectations. A simple cure is to discharge the battery completely several times as soon as posible (every third to fourth use). The new nickel-metal-hydride (NiMH) batteries show a far less dramatic memory effect but controlling, however, especially the countdown mode is still useful. A battery's life expectation, i.e. the number of recharges possible, is limited to 500-1000 with NiCd types. For this reason you may want to avoid unnecessary depletions. But remember that a battery with a strong memory effect is as useless in practice as a worn-out one and also has a shorter life than a well-maintained one.
