Appears to be charged and had a full charge before inttermittent cut out then no turn on at all
SOURCE: ryobi 18 volt batteries wont hold a charge
Ryobi batteries are specific to each Ryobi model, so please write down which model number or the original battery part number you have. How old are the batteries?
I had the same problem with many bateries I had at home, like cell-phone batteries and also some power tool bateries. Did not have any Ryobi power tools tho, so don't hold me acountable if this doesn't apply to your hardware:)
Many batteries have the "memory effect" which means that if the battery was not completely empty when it was set to recharge it might now only recharge to the level it was emptied to, so for instance if you used the power tool for 10 mins and the battery emptied to, lets say, 90% capacity, it might occure that the next time you recharge the battery it will only charge to it's 90% maximum...doing that many times lowers the maximum recharge capacity. As I heard the new Li-Ion batteries do not have this problem.
I hope this makes some sence as my english is not that good and it was a bit hard explaining my thoughts:)

Solution is two fold. Will try the freeze and re charge approach today and do this a few times. The long term soluiton is to purchase two Lithium batteries and a duel chemical charger. Expensive solution but seems it will work.

Hi, Thanks for getting back to me. The yellow and blinking red indicate a defective cell. Since it has lithium cells and is that new any repair to it would be a waste of your time. Ryobi tools purchased in 2008 have a 2 year warranty. I am guessing you probably got it at a home depot and you should return it under the warranty. All new Ryobi tools have a three year warranty. Good Luck! and Thanks for using fixya!

Hi,
You can download the manual at www.managemyhome.com. I have the Ryobi 720r and the sparkplug is a champion RDJ7Y.
Good luck!
