Question about Ryobi Multi-Volt Battery Charger

7 Answers

Ryobi Model 1412001, 16vdc, 2A

Hi, I'm trying to determine if the batteries or the charger is dead. Neither battery will hold a charge, and when I put them in the charger I get both the Charge Plus(Yellow) and the Fully Charged(Green) indicator lights. There is voltage (24.2 vdc) and current present on the charger. The batteries are #1314702, 14.4v Any advice would be appreciated! Thanks, Dave

    If the charger is displaying two states at the same time that indicates the problem might just be the charger. That is why I asked for help troubleshooting the charger.
    Maybe next time, you could actually read what was written before you jump out with a smart-mouthed response.
    If this is the level of professionalism that is normal for this site, you won't last long.

    I have a Ryobi 18.0 volt charger #1423701. It has worked perfectly until last month. When I put a battery in to charge it the Charge Plus (yellow) and the Fully Charged light (green) both come on. The message on the front of the charger states if both lights are on for more than 15 minutes to see the manual. Un fortunately, the manual is has been lost and I don't know if the charger is bad or the battery is bad. It happens with 2 batteries that I have ran all the way down. Can you help me. Thanks, James Neal

    Forgot to mention there was no need to buy anything, cross wire anything, hot wire anything, order anything, or register for anything. Hope that helps.

Same thing was happening with my Ryobi 18V Nicad Charge + batteries. I boujght a 18V Chicago Electic quick charger from Harbor Freight tools, and just jumped the wires to the battery while monitoring the voltage with my meter. It started around 9v, and while the Ryobi Charger did nothing, the Chicago electric charger cycles on/off repeatedly till the voltage goes up to around 20 volts or so. At that time, I simply put the battery in the Ryobi Charger and it instantly went to the red "fast charging" mode. Seems it needs some decent battery in the battery before it will actually charge it. FYI. the charger from Harbor Freight #43933 cost me $4.95 !

I've open the charger and found that Q4 is open. But they have removed the part number from the component so you can't get a replacement.

I had the same problem, but when I saw hotrod182s post that raised a flag in my mind so I connected a battery eliminator to the battery for a couple of minutes and put it back in the charger and now its working.

I found out the probem is the battery, not the charger. The cells of the batteries build up corrosion on the terminals inside and won't charge any longer. There's a guy on ebay who sells a method of revitalizng the battery. I tried it, it works.

Any battery left in a charger is still hooked up to a circuit. Depending on the charger this can mean a slow discharge is possible. Ryobi's Maintenance Charge Mode means the charger will 'refresh' the battery at regular intervals, usually every 30 days. A battery's lifespan is determined by how many times it is discharged/recharged so to get 'the longest possible battery life' it is desirable to reduce the number of times a battery is recharged. One way is to use the battery until it is dead or near so another is to remove the battery from the charger when it's fully charged to reduce the number of times the charger refreshes the battery.

Ryobi 18v One+ battery won't hold a charge. I have two of them and neither one will hold the charge. The charger is the Ryobi 18v charger plus.


Does it not hold a charge, or will the charge not indicate "fast charge"? I had to apply a initial jump charge on the battery to get it up to 20 volts, then I put it in the Ryobi Charger, and it started charging it.

Schumacker battery charger problem?


You are charging. The meter corresponds to the level of charge in the battery. Try setting to 10 A for 4 hours, battery should be half-way up. To determine if battery id dead.. leave battery off charger once it is fully charged...test with a voltmeter after 10 min.....battery should still be above 12v...after1 hour it should still be above 12v...if not battery is spent.

If the drill has a short in it, then yes, it could short the battery out. Probably in the trigger switch.
