BatteryInformation
Propercare will improve the performance andextendthe life and cycle lifeofyour battery. Please
followthese simpleguidelinesto getthebest useoutof yourbattery.
Power loss
Whennotinuse,abatterywillgraduallyloseitspower,thisisnormal. Therateofpowerloss
dependson the battery typeand is approximately:
2% / Day for a Ni-MH Battery
0.2% / Day for aLi-IonBattery
Battery storage
Outsidethe computer
If you are going to store a battery outside your computer for an extended period you must:
· Charge the battery to at least 40% capacity prior to storage.
· Followsteps 1 through 3 approximatelyevery 30 days:
1.Completely recharge thebattery.
2.Usethebattery untilitisfullydischarged
3. Recharge the battery to at least 40% capacity.
Inside the computer
If a fully charged battery is stored inside the computer and the battery is not used for more
than30 days, you must followthese steps:
1. Completelyrechargethebattery.
2. Usethebatteryuntilitisfullydischarged
3. Recharge the battery to 100% capacity.
(In this case it doesn’t matter whether or not the computer is being used)
Note: An empty battery will become damaged if stored too long and by following these
steps the battery cycle life and the battery life will increase.
Battery Testing
Testingabatterywhileitstemperatureremainshighcouldpossiblycauseinaccurate
measurements,thereforewestronglyrecommend:
· Waiting30minutesbeforetestingabatterythathasjustbeenfullycharged.
· Waitingatleast30minutesbeforerechargingafullydischargedbattery.
Note: All battery testing should be done on a fully charged or fully discharged battery.

12
Battery alarm
Thebatteryalarmisactivatedbyaprogramandwillsoundwhenthebatterypowerislow.
Note: If a fully discharged battery has been charged for less than 3 minutes, this program will
not be activated.
This happens when these 3 steps occur:
1. The computer is being used and the low battery alarm sounds.
2. The AC adapter is connected to charge the battery while the computer continues to be
used.
3. The adapter is unplugged within the first 3 minutes of charging.
After this sequence of steps, the computer will eventually shutdown without the low battery
alarm sounding and you will lose any work you have entered and not saved.
Therefore you should make sure that the AC adapter is firmly plugged into the computer when
charging the battery.
