Cordless power tools

Okay what happens sometimes is the charger gets into a feed back loop. What to do is remove the battery unplug the charger wait a few seconds (Maybe 20/30) plug the charger back into the outlet and then put the battery back in the charger. It should start to charge again and a few minutes later go to the blinking for full charge green.

It'll happen the other way as well meaning if the battery gets a memory (they say they don't but they do) you need to unplug the battery let is sit till it's cool and put it back on charge again. I've had this problem many times and have put it on charge and back off several times with in 15 minutes before it started to charge as it should.

Also these batteries do have a life span and if it's a three year old battery with many charges it could be failing meaning it just won't take a full charge.

This is indicating the battery is too hot to charge, usually after coming off the tool right after some hard work. During the charging process the battey heats up so if you charge a hot battery, thereby making it hotter, you shorten the lifespan of the battery considerably. If you are getting a hot/cold pack delay indication on the charger, it should automatically start charging once the battery has cooled down sufficently.

Let the thing drain completely down to nothing.  When the pop up window says you gotta plug the thing in, just ignore it and do your thing.  When the computer shuts off by itself, hold down the power button for 5-10 more secs to fully drain the thing.  Then plug your computer in and let the battery charge for a good 6-8 hours.  Then unplug the charger and let the battery sit and cool down for about 15 minutes.  This is called conditioning the battery and should be done once every other charge.  Also, its a good idea to turn off your wi-fi if your not using it, bring the brightness down on your screen, and close any non-essential applications that are running.  Cheers old chap.

The battery is failing and is starting to degrade. If you can't get it to take a full charge, you might want to mark it for use in your flashlight only, but eventually, the battery won't take any charge and you'll have to replace it.

The good news is the the Ryobi battery tools have the lowest cost of rechargeable batteries in the marketplace. I believe you can purchase a 2 pack at Home Depot for under $40.00 which is very inexpensive for two (2) Ni-Cad batteries.

If you battery is from a new tool set, just simply contact Ryobi Customer Service and they'll address the problem with a replacement. If the batteries are ones you've been using for awhile, then go for the replacement.

NiCad batteries should be used until the tool slows down to the point where you can't use it. Then remove the battery from the tool and allow it to cool down for about 15-20 minutes before placing it in the charger. This will provide the maximum working life for your batteries.

When you use a battery powered tool, the battery gets warm/hot as it discharges, and then it gets heated up during the recharging process, so letting it cool down after using it, will prolong the useful life of that battery.

Hope you find this Very Helpful and best regards!

I wont exactly call this solved but I called duracell and they think the batteries are old. They are sending me a new set of batteries.
