Modern Battery technology does not require it.

True, they reckon the new batteries don't require it.......but, it can't hurt.

I fully charge and then drain as quickly as possible to flat 3 consecutive times. Fully charge again and use normally. On my laptop I use mains the majority of the time, but make sure that I use battery 3 or 4 times a week and drain to within 10% of flat before recharging to full.

It's 3 years old and the battery is still good for 2 hours on a full charge.

The whole concept goes back to the previous technology Nicad batteries which suffer from "Memory"

Lithium batteries and Smart charging from the device and chargers - forget it you will achieve nothing apart from waste several hours of your time
