How to maximize the performance of your laptop ac adapter:

Prevent the Memory Effect -Keep the laptop adapter healthy by fully charging and then fully discharging it at least once every two to three weeks. Exceptions to the rule are Li-Ion adapters which do not suffer from the memory effect.

Keep the laptop Adapters Clean - It's a good idea to clean dirty adapter contacts with a cotton swab and alcohol. This helps maintain a good connection between the adapter and the portable device.

Exercise the Adapter - Do not leave the adapter dormant for long periods of time. We recommend using the adapter at least once every two to three weeks.

If you don't plan on using the laptop adapter for a month or more, store it in a clean, dry, cool place away from heat and metal objects. NiCad, NiMH and Li-Ion adapters will self-discharge during storage; remember to recharge the adapters before use.
