It takes approximately 1½ hours to charge a completely discharged battery when the computer is off. If you use the system while the battery is recharging, it can take up to 6 hours. If the battery still has some charge left when you start charging, the time will be less.
If you have additional batteries, it is a good idea to keep them fully charged so you can replace the battery in your computer when it runs low. This is especially useful if you are travelling and run the computer only off the battery; an extra battery or two extends the length of time you can power the computer without the AC adapter.
Rechargeable batteries like the one supplied with your ActionNote have a charge “memory.” If you frequently start to recharge the battery before it runs out completely, it starts to “remember” this discharge level. When you use it again, it may stop supplying power at that level.
To reduce the memory effect and extend the life of your battery, you should let it discharge completely whenever possible before recharging it. If you use the computer every day, you should completely discharge the battery at least once a week.
If you find that over time the battery is losing its charge sooner, the life of the battery may be reaching its end. Try letting the battery discharge completely; then recharge it. If this fails, you may need to replace it with a new battery.
Note
When your battery will no longer recharge, please contact your local government agency responsible for hazardous waste disposal. NiCad batteries are considered hazardous waste and should be recycled or disposed of properly.
