Dell Precision M40 Laptop Battery Articles & Tips

A new Dell Precision M40 Laptop Battery comes in a discharged condition and must be charged before use (refer to the devices manual for charging instructions). Upon initial use (or after a prolonged storage period) the digital camcorder Dell Precision M40 may require three to four charge/discharge cycles before achieving maximum capacity. New Dell Precision M40 needs to be fully charged and discharged (cycled) a few times before it can condition to full capacity. Rechargeable batteries undergo self-discharging when left unused. Always store a Laptop Battery pack in a fully charged staged for storage.When charging the Dell Precision M40 for the first time the device may indicate that charging is complete after just 10 or 15 minutes. This is a normal phenomenon with rechargeable batteries. Remove the camcorder batteries from the device, reinsert it and repeat the charging procedure It is important to condition (fully discharge and then fully charge) the Dell Precision M40 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 the 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 the user's manual. If the battery will not be in use for a month or longer, it is recommended that Dell Precision M40 be removed from the device and stored in a cool, dry, clean place. Invest in a good charger for your camcorder. Ni-MH batteries should not be charged in a NiCad charger, unless the charger is specifically made for both chemistries. There are cheap chargers and there are expensive chargers. Make sure the charger you get has good reviews and is well made. Chargers with micro-controller chips are usually the best choice of your digital camcorder. Be sure to store your Laptop Battery properly. Do not leave your batteries in a hot car, or in humid conditions. The best storage conditions are a cool, dry place. The refrigerator is fine if you stick in a packet of silica gel with your Dell Precision M40 in a sealed bag to keep them dry. It is a good idea to charge your NiCad or Ni-MH batteries fully before use if they have been in storage.

Upgrade my Dell Precision M40 Laptop Battery From Ni-MH to Li-ion

NiCad, Ni-MH and Li-ion Dell Precision M40 Laptop Battery is all fundamentally different from one another and cannot be substituted unless the Camcorder has been pre-configured from the manufacturer to accept more than one type of battery chemistry. Please refer to your manual to find out which rechargeable battery types the laptop device supports or use our Dell Precision M40 Battery Finder above to find all the compatible Laptop Battery for your device. It will automatically list all of the battery chemistries supported by your specific device. If your device does allow you to upgrade the battery from Ni-MH to Li-ion, you will typically get longer run time. For example, if your Camcorder uses a NI-MH battery that is 9.6 Volts, 4000mAh and the new Li-ion Laptop Battery is 14.4 Volt, 3600mAh, then you will obtain longer run time with the Li-ion battery. Example: Li-ion: 14.4 Volts x 3.6 Amperes = 51.84 Watt HoursNi-MH: 9.6 Volts x 4 Amperes = 38.4 Watt HoursThe Li-ion is stronger and has longer run time.
