removing Dell battery message "Your battery is able to charge normally. However it is reaching the end of its usable life"

By design, Dell laptops will warn you as their battery life starts to decline.  When you log in, Windows will display this message "Your battery is able to charge normally. However it is reaching the end of its usable life"

My comment on this message is typically this:

---

All rechargeable batteries have a limited life span. It varies from battery to battery, but a battery typically loses 25% of its life per year (so a 2 year old battery lasts half as long as it did when it was new).

While it’s typical for a battery to last less long, it’s not so much of a problem unless the battery life no longer meets your needs. If you say the word, I’ll begin the process of requesting a new battery on your behalf.

I found this elegant way to remove the warning which seems to work on all E series Dell Latitude laptops.
