1. Your sony vaio vgn-fs740/w battery comes in a discharged condition and must be charged before use (refer to the user’s manual for charging instructions). Upon initial use (or after a prolonged storage period) the Battery may require three to four charge/discharge cycles before achieving maximum capacity.
2. When charging the sony vaio vgn-fs740/w laptop batteries for the first time your machine may indicate that charging is complete after just 10 or 15 minutes. This is a normal phenomenon with rechargeable batteries. Simply remove the battery from the machine and repeat the charging procedure.
3. It is important to condition (fully discharge and then fully charge) the vaio vgn-fs740/w battery every two to three weeks. Failure to do so may significantly shorten the Battery’s life (this does not apply to Li-Ion batteries, which do not require conditioning). To discharge, simply run your device under 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.
4. If your sony vaio vgn-fs740/w battery will not be in use for a month or longer, it is recommended that it be removed from the device and stored in a cool, dry, clean place.It is normal for a battery to become warm during charging and discharging.
5. A charged battery will eventually lose its charge if unused. It may therefore be necessary to recharge the sony vaio vgn-fs740/w laptop batteries after a storage period.

Taking Care Of Your New Battery Pack

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 laptop battery pack 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 battery pack 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 sony vaio vgn-fs740/w 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 battery pack, 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 battery pack’s useful life. Lithium Ion batteries do not require conditioning.
5. It is normal for a battery pack to get warm when charging and during use. However, if the vaio vgn-fs740/w 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 sony vaio vgn-fs740/w laptop batteries 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.
