Tip & How-To about Computers & Internet

Taking Care Of Your Laptop Battery

  1. Normally, a new battery pack comes in a very low charge condition and must be fully charged before use. Refer to the user manual of your portable electronic equipment for charging instructions.
  2. A new Dell Vostro A860 Battery needs to be fully charged and fully discharged or “cycled” as much as five times to condition them into performing at full capacity.
  3. Your equipment may report a fully charge condition in as short as 10 to 15 minutes when the new Dell Vostro 1015 Battery is being charged for the first time. This is a normal phenomenon especially for Nickel Cadmium (Ni-Cad) and Nickel Metal Hydride (Ni-MH) chemistries. When this happens, remove the dell vostro 1015 battery pack and let it cool down for about fifteen minutes then repeat the charging procedure.
  4. “Conditioning” (fully discharging and then fully charging) is necessary so as to maintain the optimum performance of a sony vgp-bps8 battery, and is recommended at least once a month particularly for Ni-Cad and Ni-MH batteries. Failure to do so could result in reduced charge capacity and can significantly shorten the sony vaio vgn-fz battery pack’s useful life. Lithium Ion batteries do not require conditioning.
  5. It is normal for a acer aspire 1410 battery pack to get warm when charging and during use. However, if the acer aspire 1410 battery pack gets excessive hot, there may be a problem with the portable electronic equipment’s charging circuit and should therefore be checked by a qualified technician.
  6. Rechargeable batteries undergo self-discharging when left unused for long periods of time. This is normal particularly in the case of Ni-MH and Li-Ion chemistries. For best results, always store a battery pack fully charged. It should be removed from the equipment and kept in a cool, dry and clean place.
  7. The amount of runtime a hp 510 battery produces depends on the power requirements of components in your electronic equipment. This could be the hard drive setting, screen intensity and back-lighting on notebook computers, the liquid crystal display (LCD) screen and floodlight feature in a video camcorder, or the tri-mode communications network of a cellular phone. Always refer to your equipment’s user manual for power management settings.

CHARGING THE BATTERY PACK
Battery packs for this tool are shipped in a low charge condition
to prevent possible problems. Therefore, you should
charge them until the green LED on the front of the charger
comes on.
NOTE: Batteries will not reach full charge the first time they
are charged. Allow several cycles (operation followed by
recharging) for them to become fully charged.
CHARGING A COOL BATTERY PACK
See Figure 3.
If battery pack is within normal temperature range, the red
LED on charger will come on.
NOTE: If the charger does not charge the battery pack
under normal circumstances, return both the battery pack and
charger to your nearest Ryobi Authorized Service Center for
electrical check.
n Charge the battery pack only with the charger provided.
n Make sure the power supply is normal household
voltage, 120 volts, 60 Hz, AC only.
n Connect the charger to the power supply.
n Place the battery pack in the charger aligning raised rib
on the battery pack with the groove in the charger.
n Press down on the battery pack to be sure contacts on
the battery pack engage properly with contacts in the
charger.
n Normally the red LED on charger will come on. This
indicates the charger is in fast charging mode.
n Red LED should remain on for approximately 1 hour
then the green LED will come on. Green LED on
indicates battery pack is fully charged and charger is
in maintenance charge mode.
NOTE: The green LED will remain on until the
battery pack is removed from the charger or charger is
disconnected from the power supply.
n If both yellow and green LEDs come on, this indicates
a deeply discharged or defective battery pack.
Allow the battery pack to remain in the charger for 15
to 30 minutes. When the battery pack reaches normal
voltage range, the red LED should come on. If the
red LED does not come on after 30 minutes, this may
indicate a defective battery pack and should be
replaced.
n After normal usage, a minimum of 1 hour of charging time
is required to fully recharge battery pack.
n The battery pack will become slightly warm to the
touch while charging. This is normal and does not
indicate a problem.
n Do not place the charger and battery pack in an area of
extreme heat or cold. They will work best at normal room
temperature.
NOTE: The charger and battery pack should be placed
in a location where the temperature is more than 50°F
but less than 100°F.
n When batteries become fully charged, unplug the
charger from power supply and remove the battery
pack.

I would suspect poor quality batteries in the battery pack or memory in the pack from recharging a partially charged pack instead of letting it work to flat condition. New batteries take hours to fully charge so if you just plugged in the charger for a short time before use then the battery pack may nit have been fully charged to start with.

The initial battery of my Acer Travelmate 2480 packed up and I ordered and installed a new one. However, the laptop remains on "AC Only" power and the battery is not charged, giving a "Remaining Battery Life" of 255%. If I remove the AC Power, the laptop goes dead. Can you please indicate if there is a way to reset the "AC Only" or clear it or a way to get the battery charged?


RTFM You can download the manual by googling "acer travelmate 2480 manual" (without the quotes). Or just click here

According to the Acer manual:

"Conditioning a new battery pack
Before you use a battery pack for the first time, there is a
"conditioning" process that you should follow:
1 Insert the new battery without turning the computer on.
2 Connect the AC adapter and fully charge the battery.
3 Disconnect the AC adapter.
4 Turn on the computer and operate using battery power.
5 Fully deplete the battery until the battery-low warning appears.
6 Reconnect the AC adapter and fully charge the battery again.

Follow these steps again until the battery has been charged and
discharged three times.
Use this conditioning process for all new batteries, or if a battery hasn't
been used for a long time. If the computer is to be stored for more
than two weeks, you are advised to remove the battery pack from the
unit.

Warning: Do not expose battery packs to temperatures below 0°C
(32°F) or above 60°C (140°F). Extreme temperatures may adversely
affect the battery pack.

By following the battery conditioning process you condition your
battery to accept the maximum possible charge. Failure to follow this
procedure will prevent you from obtaining the maximum battery
charge, and will also shorten the effective lifespan of the battery.
In addition, the useful lifespan of the battery is adversely affected by
the following usage patterns:
• Using the computer on constant AC power with the battery
inserted. If you want to use constant AC power, you are advised to
remove the battery pack after it is fully charged.
• Not discharging and recharging the battery to its extremes, as
described above.
• Frequent use; the more you use the battery, the faster it will reach
the end of its effective life. A standard computer battery has a life
span of about 500 charges."
