Answer: 
Check you manufacturer's warranty. It may be covered; but, if it isn't, buy another couple of the same batteries or try Batteries Plus.

DO YOU HAVE TO FIDDLE WITH YOUR RYOBI TEK4 BATTERY CHARGER (AP4800) TO GET IT TO CHARGE?

DO YOU HAVE TO FIDDLE WITH YOUR RYOBI TEK4 BATTERY CHARGER (AP4800) TO GET IT TO CHARGE?
Not sure if you use the Ryobi Tek4 table-top charger or you're charging your battery some other way, but if you charge your AP4001 Li-ion battery using the Ryobi AP4800 external battery charger, and the charger's green indicator light does not come on immediately after putting the battery in, try this...
Always charge your Tek4 battery by placing it in the Ryobi charger base FIRST, then plugging the charger into the wall.
If you mistakenly plug the charger's a/c adaptor into the wall first before you put the battery into the cradle base, unplug the a/c adaptor from the wall, wait a few minutes for the a/c adaptor to discharge fully, then insert the battery into the charger base and plug the charger into the wall. Simple as that. (this took me about a month of Sundays to figure out : )
The charger's green light should come on immediately indicating that it's charging. If not, your battery is likely dead from age or it's defective.
Not sure why Ryobi doesn't explain that their charger usually only works by doing it in this order, but it does. Read Less

Rated 4.0 out of 5 by 50 reviewers.
Rated 5.0 out of 5.0 by I like this 4V battery's shape rather than the square type platform battery used in higher voltage drills because it fits inside of the electric drill's handle rather than the outside. When the battery needs charging, remove it & insert another battery. I looked to buy Ryobi's HP108L 8 volt drill; but, it has a built-in battery which I believe is charged by using a minature USB port like your Smartphone which negates the drill's function until after the unit has recharged. I'll stick with my 4 volt model with an extra battery or two. October 29, 2016
Rated 4.0 out of 5.0 by good value purchase Added to the value of the 4 volt items by keeping a few more extra batteries. They hold a charge very well and by having a extra one on hand makes things better. September 1, 2016
Rated 5.0 out of 5.0 by Great Battery works great , lasts for days. So far I would say it's top of the class August 2, 2016
Rated 5.0 out of 5.0 by Excellent Battery I purchased the battery as a secondary back due to the original battery showing signs of wear. I have used the back up battery and it worked perfectly. Charged up just fine prior to first use and lasted for hours. June 28, 2016
Rated 1.0 out of 5.0 by Defective Purchased battery and charger and battery was defective...Wasn't worth my time to return it so I took the loss May 17, 2016
Rated 5.0 out of 5.0 by It works The original died after minimal use. Perhaps that was the issue. In any case, the replacement works great. March 22, 2016
Rated 5.0 out of 5.0 by TEK4 4-VOLT LITHIUM-ION BATTERY next time don't cover it with a ton of stickers - Couldn't read anything on the box March 15, 2016
Rated 4.0 out of 5.0 by battery for an previously purchased screw driver light weight, easy to use, long-lasting, and compact. not so good for driving screws in new work. December 29, 2015
