Most dell laptop batteries last 18-24 months with average use. This is equivalent to 500-800 charging cycles. Average use of a battery will eventually drain the battery’s ability to hold a charge or there may be some adjustments that you can make to get better performance from your battery. However, if your battery is old and is getting less than half of it’s original run-time, then it may be time for a new battery. If you use your dell laptop battery everyday, use it for gaming, video streaming and are on WiFi constantly, the dell laptop will drain the battery run-time and over all life much quicker. Such heavy use can render the battery dead in as little as one year with heavy dell laptop use. Get maximum performance from your dell laptop battery by following a few suggestions below:
Condition New Batteries
New dell laptop batteries come in a discharged condition and must be fully charged before use. It is recommended that you fully charge the battery to 100% and let the battery discharge completely on its own. Repeat this procedure 3-4 times to break in the battery and so each battery cell can reach it’s full charging potential. Then condition or exercise the battery at least once a month. Li-Ion battery need only be drained to about 40%, not a full discharge for monthly maintenance, however constant shallow charges should still be avoided. Sometimes it’s not conditioning that the battery needs, but a battery recalibration. Constant shallow charging will confuse the battery and it may need to be re-calibrated.

Avoid Memory Effect
Keep your dell laptop battery healthy by fully charging and then fully discharging it at least once a month. Li-Ion batteries do not suffer from the memory effect, but they too still need conditioning at least once a month with a discharge to about 40% and should not be overcharged.
Remove Battery when Using AC/DC Power Source
Dell Laptop batteries are in constant charge and discharge state when you have the AC/DC adapter plugged into the computer and using the computer with the battery installed. Removing the battery while using the AC/DC adapter will help prolong the life span of the battery since most last 500-800 charging cycles or 18-24 months. These frequent shallow charges do not allow all of the battery cells to properly condition for optimum battery performance.
Don’t Mix Chargers & AC/DC Adapters
Not all dell laptops of the same brand use the same type of charger/adapter. Do not assume that the same charger your friend uses on his Toshiba will be the correct one for you model of Toshiba. Every dell laptop requires it’s own specific specs and both the in and out source specifications Amps and Volts must be correct for your laptop model and battery chemistry. Mixing or using the wrong charger can damage the battery and the laptop. You may not notice any difference at first, but the laptop or battery may show signs of a problems later. Do not use a swollen battery. Carefully remove and contact a local recycle center or repair shop for advice on discarding the battery.
Reduce or Set Your Laptop to Battery Saver Mode
Most laptops allow you to adjust the settings to battery saver mode. Turning down the monitor brightness and turning off programs running in the background will also help in reducing drain on the battery. Remember that WiFi, Gaming and Video Streaming eats up a lot of battery power. We recommend using the AC/DC adapter when you can if on WiFi, Gaming and Streaming Video.
Keep your Batteries Clean
Cleaning dirty battery contacts with a cotton swab and alcohol will help maintain good connections between the battery and the electronic device.
Exercise the Battery
Condition the battery at least once a month. If your battery has not been used for a long period of time, perform the new battery break in procedure described above (condition).
Laptop Battery Storage
NiCad, NiMH and Li-Ion batteries self-discharge during storage Batteries need to be broken in before use. If you don’t plan on using the battery for at least a month or more, the battery should be stored in a cool dry place. Do not leave the battery inserted in the laptop for long periods of time with the AC/DC adapter plugged in constantly charging the battery. Not only will this reduce the battery’s life, it can over charge the battery and damage the laptop.
