Almost all notebooks today utilize rechargeable panasonic nv-ds15b batteries. Rechargeable camcorder batteries provides many benefits over earlier Nickel-Metal Hydride (NiMH) or Nickel Cadmium (NiCd) Batteries, including less mass, better performance, and insusceptibility to the so-called "memory effect". Despite these benefits you can maximize your panasonic nv-ds15b camcorder batteries's lifespan by following these maintenance tips:

• New batteries must be fully charged before use: To put your nv-ds15b battery in optimum condition for long-term usage, please fully charge the panasonic camcorder batteries before its first use. Very importantly as well, for the first 3 charge cycles, always fully charge before use and fully discharge before recharging.
• Calibrate the panasonic nv-ds15b computer battery every few months: Almost all notebook batteries are created with an internal microprocessor, which provides an estimate of replacement for panasonic nv-ds15b battery conditions such as number of multi-charges, discharges, full charge capacity and cycle charge count. The full charge capacity will become a little inaccurate after a few months and calibrating it can help restore the rechargeable battery's performance.
• Use your battery in the proper conditions: Generally speaking, batteries work best at around 68°F (20°C), but temperatures between 32°to 95°F (0°to 35°C) will allow a panasonic nv-ds15b to works in good condition too. Allowing your replacement for panasonic nv-ds15b battery to work in conditions that are too hot or cold can lower its performance. It may also have a negative influence on the battery’s lifespan as well.
• Store your panasonic nv-ds15b pc battery in the proper conditions when not in use: If you don't plan to use your notebook for a month or more, we recommend the nv-ds15b external battery pack be stored separately in a clean, dry and cool place. Please also ensure that the nv-ds15b battery plus has about a 70% charge remaining. During storage the rechargeable 319411001 battery will perform a slow self-discharge, so we do not recommend storing it for a very long time, because it can impact the wellbeing of the replacement battery.
