1. common condition during first time battery use or using a battery that has been discharged for several months The charger light may go out after only five to ten minutes indicating that it is fully charged when it is not Should this happen simply leave the battery on the charger for about an hour remove it then return it to the charger immediately The battery will resume normal charging and the charger light will indicate when the battery is ready for use 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 continually only partially discharged before re charging 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 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 two to three weeks Batteries can be discharged by unplugging the device s AC adaptor and letting the device run on the battery until it ceases to function This will insure your battery remains healthy www compusave ca E mail support cs compusave ca
2. Staying Alive Battery Care Guide Like all rechargeable batteries a notebook computer battery s ability to hold a maximum charge will decrease over time with use Lithium ion batteries used in notebook computers typically have a lifespan of 300 to 500 charge cycles After a year of use or 300 charge cycles a Lithium lon battery holds only about 80 percent of its original capacity But there are ways to extend a notebook battery s life reducing the need to buy additional batteries which in turn is good for the environment First conserve battery power by reducing power consumption on your notebook Hewlett Packard recommends several steps such as keeping the computer cool between 18 and 25 degrees Celsius You can also try adjusting screen brightness removing peripherals and lowering processor speed Second because high temperatures accelerate the deterioration of Lithium ion cells keep the notebook away from prolonged exposure to heat for example don t leave it in your car ona warm day Also remove the battery if the notebook is turned off and not plugged in to an AC adapter for more than two weeks or if the notebook is plugged in to AC power continuously for more than two weeks Third calibrate the battery When users power up in fits and starts and then recharge without fully draining the battery it reduces the amount of power available in a single charge cycle and can render the battery meter inaccurate Ther
3. Website batteries will self discharge during storage remember to break them in before use Sealed Lead Acid SLA batteries must be kept at full charge during storage This is usually achieved by using special trickle chargers If you do not have a trickle charger do not attempt to store SLA batteries for more than three months To get maximum performance from your battery fully optimize the notebook s power management features prior to use Power management is a trade off better power conservation in exchange for lesser computer performance The power management system conserves battery power by setting the processor to run at a slower speed dimming the screen spinning down the hard drive when it s not in use and causing the machine to go into sleep mode when inactive Your notebook user s guide will provide information relating to specific power management features It is important to condition fully discharge and then fully charge the battery every two to three weeks Failure to do so may significantly shorten the life of the battery To discharge simply run the battery s power until it shuts down or until you get a low battery warning Then recharge the battery as instructed in your user s manual If the battery will not be in use for a month or longer it is recommended that you fully charge the battery remove it from the device and store it ina cool dry and clean place It is normal for a battery to become warm durin
