20 Most Recent Ryobi Two 18V Lithium-Ion Batteries + Lithium-Ion Charger Upgrade Combo Pack Questions & Answers

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!

The battery cells inside lithium ion batteries (and other types of batteries) tend to corrode if they become wet for a given period of time. They need to be dried out immediately to avoid corrosion. Unfortunately, it seems like it is too late to dry out yours. Your battery will need to be carefully disassembled using procedures on fixya and the corroded cells replaced with similar quality cells. The cells in Ryobi batteries are spotted welded in place and these welds need to be broken carefully using a Stanley knife. Replace the cell(s) with new ones or from other disassembled batteries and solder them in place. Check for cell voltage imbalance (see other solutions on fixya) and reassemble. Good quality Panasonic Li Ion cells can be purchased for about $4 each on ebay. If you go this route, I would recommend replacing all cells, not just the corroded ones.

check output on transformer, 2 check pcb ,could be a regulator

no, I would not try this. You can charge a nicd battery on a lithium-ion charger but not the other way around.

Lithium-Ion batteries require careful charging and temperature monitoring while in the charger. Ryobi's Charging station monitors many functions and shuts off when the battery has gone through a complete charge. This is indicated by a steady Green light. Once the Charge indicator is a steady green the charger stops charging. With any battery It will slowly discharge and I don’t think the Ryobi will maintain a battery that is never removed. For example, if after a complete charge cycle if the battery was left there for 2 years and then you went to use it, it would likely be completely discharged. However if the battery charger is unplugged then plugged back in a new charge sequence would start. I lose power at my house about every 6 months or so. Once power is restored a new cycle would start and the charging cycle begins again.
Hope this helps and have a great day.

You need to have the charger tested, if you know that batteries are good then what else could it be. This LIon charger has a logic circuit in it like a computer.

The battery will power your equipment for 30 to 45 minutes, that is normal. What you're thinking of is the lifespan of a lithium battery. It with your battery will last 10 times longer than a regular NiCad battery. So you will be able to charge the battery and use it Hundreds of times before the Battery Life is depleted. Sounds like it's working as designed

Receipt will do nothing for you if it is out of warranty. Normal warranty is for three years. Write to the company regarding your situation - see if your unit has a serial number that can give indication of age of unit. Perhaps they will replace the charger for you. Make sure that the charger cord/connections are good and that unit is receiving power from wall.

If you are sure your charger is working properly then your one battery may be shot.. i even had a new battery quit charging and had to replace it. they do not come cheap.

time for new drill and batts

hello don... check to be sure that the tools are 18 volt and not 12 volt. If they are 18v then go to this website to contact ryobi directly https://register.ryobitools.com/contact_us/new

After looking at the manual for your charger, it looks like most of the Ryobi chargers like the P113, P114, P117, P118 will charge your battery. The connector on the battery looks the same as the P103 and P104 used here in the U.S.

The Ryobi charger will flash green as it charges and then remain steady or slowly flashing green when fully charged. Flashing red means testing and if it remains steady or slowly flashing red it is defective.

I had the same problem. Your battery sounds like it got drained too much. The voltage on the battery is too low for the charger to charge. I looked on YouTube (how to charge battery that won't charge). I actually tried this today. I had a battery attached to one of those flashlights from a combo pack and the battery was drained down to 0.64v. The video I watched said take a higher voltage batter and boost it. Like a 20v to boost your 18v. Attach wires from one to the other. + to + and - to - I didn't have any. So what I did was stick 9v batteries together + to - in series I had 5 laying around. I taped a wire to the exposed terminals on the two end batteries and tapped the wire on the battery, which only brought it up to about 2.3volts. Then I just held the two wire on the battery for about a minute. It went up to about 6.3 volts I plugged it in the charger and it finally started charging. I don't know how well it will keep a charge. The batter is 10 or 12 years old. Hope this helps. And check YouTube. There is a lot of videos there.

NO THE OLD CHARGER FOR THE BLUE ONE+ TOOLS WILL ONLY CHARGE NICD BATTERIES. HOWEVER THE INTELLIPORT DUAL CHEMISTRY CHARGER WILL CHARGE BOTH NICD AND LION BATTERIES. ALL BATTERIES ARE COMPATIBLE WITH ALL ONE+ TOOLS

NO! Never charge lithium batteries in a charger designed for nickle based batteries like the NiHi your old charger was meant for. Ryobi did design the new Lithium charger to be backwards compatible so you can charge your older 18V NiHi batteries in the Lithium 18V charger.
Also note, NEVER miss-match the voltage, for example, make sure you are not trying to charge 12V batteries in an 18V charger unless the manufacturer has specifically stated that the charger is capable of multiple voltages.

test the battery with a multi tester then if there is power your drill is the problem.

Yes. The first step is to open the battery and check the condition of the wiring for breaks, corrosion, etc. Also check the condition and voltage for the individual 18650 cells. Ryobi batteries are relatively easy to disassemble using available tools, see posting below. https://www.ifixit.com/Guide/Cell+Re-balance+of+Ryobi+One%2B+18V+Li-ion+Battery+%28130501002%29/13286 Depending on the findings, some parts may need replacing. If you replace the 18650 cells, use new ones which are easily found on eBay.

Rebuilding the Lithium batteries is a waste of time and money. For starters the cells cost a minimum of $5 ea and a low power pack takes 5, so now you are in for $25 without doing any work. You can pick up packs on eBay for around $30 - $40 if you shop around. If you know what you are doing, you can strip cells from bad packs and test them to find good ones and then rebuild with those. It can be tricky and you may get mixed results.
