There are several steps you can take to insure that you get maximum performance from your 20V 4.5A 90W Square Tip AC Adapter Charger Compatible with Lenovo Thinkpad T440 T440S L440 E470 X250 battery:

Breaking In New 20V 4.5A 90W Square Tip AC Adapter Charger Compatible with Lenovo Thinkpad T440 T440S L440 E470 X250 Batteries - new batteries come in a discharged condition and must be fully charged before use. It is recommended that you fully charge and discharge your new battery two to four times to allow it to reach its maximum rated capacity.
Preventing the Memory Effect - Keep your 20V 4.5A 90W Square Tip AC Adapter Charger Compatible with Lenovo Thinkpad T440 T440S L440 E470 X250 battery healthy by fully charging and then fully discharging it at least once every two to three weeks. Exceptions to the rule are Li-Ion batteries which do not suffer from the Memory Effect.
Keep Your 20V 4.5A 90W Square Tip AC Adapter Charger Compatible with Lenovo Thinkpad T440 T440S L440 E470 X250 Batteries Clean - It's a good idea to clean dirty battery contacts with a cotton swab and alcohol. This helps maintain a good connection between the battery and your portable device.
Exercise Your 20V 4.5A 90W Square Tip AC Adapter Charger Compatible with Lenovo Thinkpad T440 T440S L440 E470 X250 Battery - Do not leave your battery dormant for long periods of time. We recommend using the battery at least once every two to three weeks. If a battery has not been used for a long period of time, perform the new battery break in procedure described above.
Battery Storage - If you don't plan on using the battery for a month or more, we recommend storing it in a clean, dry, cool place away from heat and metal objects. Ni-Cd, Ni-MH and Li-Ion batteries will self-discharge during storage; remember to break them in before use.
For Notebook Users - To get maximum performance from your battery, fully optimize the notebook's power management features prior to use. Power management is a trade off: better power conservation in exchange for lesser computer performance. The power management system conserves battery power by setting the processor to run at a slower speed, dimming the screen, spinning down the hard drive when it's not in use and causing the machine to go into sleep mode when inactive. Your notebook user's guide will provide information relating to specific power management features.
