Battery Knowladge

  1. Do not modify or disassemble dell u444c battery.
  2. Do not expose dell u444c laptop battery to water or other moist/wet substances.
  3. Charge Dell u444c Replacement Battery before storing. The recommended charging time should not exceed 1 hour.
  4. Do not drop, hit or otherwise abuse the battery as this may result in the exposure of the cell contents, which are corrosive.
  5. Higher Watt hours (Whr) or milliAmpere hour (mAH) on the same system under the same operating conditions means longer battery run time. For example, if you compare the same system, running the same applications, the dell u444c battery with 75Whr would provide approximately 37% more run time than the 53Whr Dell battery.
  6. Dell u444c laptop battery gets a little hot when it works, keep your laptop in a well ventilated place and keep it cool.
  7. Don't leave your dell u444c battery inactive for extended periods of time. Even if you use AC power most of time, use the battery periodically to keep it in good condition. Unplug your AC adapter when the computer is not in use to prevent overcharging.
  8. When charging your dell u444c notebook battery for the first time your computer may indicate that charging is complete after just 10 or 15 minutes. Don’t worry, this is normal with rechargeable batteries. Just simply remove the dell u444c from the laptop and repeat the charging procedure.
  9. If you have 2 or more pack of battery, it's wise to discharge and then fully charge it on battery power once a week or so, just to keep the battery fresh conditions.
  10. Do not expose the battery pack to direct sunlight. Never store or use the battery pack in an unventilated vehicle where excessive internal temperatures may be encountered.
  11. If the liquid contained within the dell u444c battery pack leaks, use large amounts of water an immediately wash off any liquid which may accidentally contact any part of the body. Remove any liquid that has contacted your clothes by washing them immediately with a synthetic detergent.
  12. As the rechargeable dell u444c battery begins to die, the user will notice a decline in the running time of the battery. When a dell u444c laptop battery that originally operated the notebook for two hours is only supplying the user with an hour's worth of use, it's time for a new one.
  13. Do not leave your battery dormant for long periods of time. We recommend using the battery at least once every three to four weeks. If a dell u444c battery has not been used for a long period of time, perform the new battery break in procedure described above.
