Battery charge problems Ryobi 18v

The charger appears to work AOK ie the green and yellow light do not stay on more than 15 minutes, however when the charge is finished the battery has nearily no live at all. For example after a complete charge I tried the battery on in my light and it lasted about a minute!!

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.

    If the freez method does not work the pos and neg terminals are marked and you can take a car 12V batery charger and put the carge leads on the Po. and Neg terminals for a minute or two and then the batery will take a charge with red light lit.

Green & Yellow light on 14.4V charger

It sounds like your battery is bad.

If both yellow and green LEDs come on, this indicates
a deeply discharged or defective battery pack.
Allow the battery pack to remain in the charger for 15
to 30 minutes. When the battery pack reaches normal
voltage range, the red LED should come on. If the
red LED does not come on after 30 minutes, this may
indicate a defective battery pack and should be
replaced.
n After normal usage, a minimum of 1 hour of charging time
is required to fully recharge battery pack.

It sounds like your battery is bad. If yellow and green are on for more than 15 minutes it probably a defective battery pack. See page 8 in the manual.

Charger not charging

Just was on a website for Ryobi drills and it states that if the yellow and green light stay on for more than 15 minutes the battery is fried. Couldn't find the link but if you do a search for Ryobi Drill 18 volt you should find the same info. It was as product review from Australia I think.

I also have a problem with the charging of Ryobi batterys. They seem to charge AOK with the green light coming on but the charge does not last at all. Not sure if the problem is with the batteries on the charger.
