Sometimes, this is a result of a battery that is too cold (below freezing-warm it up). Sometimes it can be too hot (discharged under heavy stress-let it cool down). Sometimes there may be insufficient voltage, I have had problems in older houses, get closer to the electrical panel to plug in, or you may have to wait until you get home. Red flashing may mean https://www.youtube.com/watch?v=8rZqYmPsZycthe charger or battery is to hot and must cool down before it will charge. The charger will not charge a battery if the lights are flashing. Solid Red light means it is charging and solid green light means it is charged. Plug the charger in first before putting the battery on the charger. If the charger has been dropped or hit the floor the coil inside could have broke loose and damaged the charger requiring it to be replaced. Below is an unconventional way to charge the battery if the charger is no good. BE CAREFUL how to charge broken makita BL1830 Li ion battery
sound to me like you have a bad battery, a lot of ryobi batterys don't last like they should i have had the same problem, but my battery was less than a year old and i took it back and they give me a new one.
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.
ok you need to zap the battery, if you have a jump box or a battery charger that has at least a 20 amp or better charge selection, like a engine start feature.
the post of the cordless batter has a center post marked on the sides is a plus or minus sign. the should also be some vertical slits in the plastic post on the corners, clamp the leads from the jump box or battery charger positive to positive , negative to negative. with the car battery charger you can probably slip one side of the battery clip in the plastic slot the other on the connection blade. plug in the battery charger and let it on for 5 or 6 minutes. if the battery charger has a auto shutoff the light will blink off and on but that is ok .
take the cables off and plug into the battery pack charger now you should get a red charge light and now can charge the battery.
if light does not come on try it in the drill or saw and see if you had any more charge than before if so you might need to repeat the procedure and leave it on the car battery charger a little longer
try pitting battery in charge and wiggle the battery a little to see if the green light comes on, sometimes the make contact and then loose it when you let go of the battery.if still same problem charger is probbly dead.
For others with the same problem (flashing red light won't go off)...make sure you FIRMLY PUSH the battery down onto the charger and engage the latches. Simply resting the battery on the charger will not work.
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.
