The following precautions can help you get the most out of your SONY VGP-BPS21B Battery:
Avoid Extreme Heat
Laptop Batteries deteriorate at a faster pace when exposed to high temperatures, especially when fully charged. Avoid leaving your VGP-BPS21B Battery in very hot places, like a parked car, for prolonged periods.
Avoid Long-Term Storage
Batteries are meant to be used. Because of their internal chemistry, all SONY Laptop Batteries have a protection circuit that doesn't allow the voltage to drop below a certain level. If stored for too long (typically more than 6 months without charge) the protections circuit will not allow further charge on the battery, rendering it useless. It is recommended to charge your VGP-BPS21B SONY Battery every 3 months if not actively in use. For safety, avoid leaving the battery on a charger connected to the AC outlet.
Recharge as Needed
Batteries don't need to be fully discharged to prolong their life, in fact, frequent recharges are better for the SONY VGP-BPS21B Laptop Battery than deep discharge-charge cycles.
