Take your charger out on a boat and dump it into the sea. Then go to the store and buy a new one.

SOURCE: can a bad ryobi 18 drill ruin a new 18volt ryobi battery

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

SOURCE: plug battery in and lights don't go on

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!

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 !

SOURCE: When I charge my battery in my RYOBI P110 charger

I had the same problem, my understanding was that since the batteries are nic-cad, they have a memory so in short you are supposed to charge the batteries only when they are depleted. They have to be COMPLETELY depleted the first 3 or 4 times of use. I ended up replacing the two I had, followed this and have not had any problems since. Hope it works for you.

If the batteries needed changing would the green charging light still come on and would the alarm beep when attached to scooter and turned on?


Yup. The alarm beeps if you have the charger plugged in and turn on the key even if the battery is flat. The charger won't bring a totally discharged battery up to full charge. You can charge the battery individually using an automotive style battery charger. The charger should NOT be the automatic type. It may take some time to recover a flat battery. Charge it until you can see at least 10 volts on the battery. The scooter charger can then finish up the charge. If after you go through all this and the batteries will not take a charge, then it's battery time.

My Alante Jr power chair stopped working. when plugged in ,the charger light is green which means a full charge but the led lights all ten of them on arm continuous go from side to side without stopping....


The batteries are too low for the charger to work. You need to take the batteries out and charge them separately with an automotive battery charger. This may take 2 or more days for each battery. When the voltage on the battery gets past 10 volts, you can put them back in the chair and finish the charging with it's charger.

My pride mobility victory scooter will not charge


You must charge each battery individually with an automotive NON automatic style battery charger until each battery has at least 10 bolts each. The scooter charger cannot pull up a battery with less than 10 volts.

The light is green on charger but the controls will not light up unless it is plugged in


When the charger light stays green when you plug it in it means the charger is not actually charging. Either the batteries are bad and will not take a charge anymore or the charger is not operating correctly. It sounds more like a battery issue. The battery voltage needs to be measured on each battery with a volt meter. If the voltage is less than 10 volts on either battery they both will need to be replaced.

When I plug in my Jet 3 Ultra 4500, it seems to charge - the charging lights come on - but it never charges. In fact, I can't get it to move at all, even when plugged in. I think I am using the...


when you plug in the charger do you get any amp reading on the meter located at the rear of the chair near where the charger cord plugs into the chair. When you plug in the cord the meter should deflect and read 6 amps or so. If you aren't getting any deflection of the amp meter then either the batteries are dead or the charger is bad. If you have a voltmeter you can set it to 200 volts dc and plug the leads into the charger port located under the front of the joystick Plug the leads into the 2 outter holes of the port with the charger plugged into the wall you should be reading 27-30 volts. Unplug the charger and you will be reading the battery voltage and fully charged they should read 25-27+ volts. If you aren't reading 25-27 volts without the charger plugged in you will need new batteries( anything less than 10 volts will not let the chair turn on) if you aren't getting 27-30 volts with the charger plugged in then the charger is bad and you can get or borrow an off-board charger and charge the chair thru the joystick port Hope this helps

Pheonix plus batery flat,charged up,now it is mobile but all i have on dial is single red flashing led.


John the red flashing light indicates a low battery When you charge the battery your charger should be showing a red light for power and a yellow light. When the batteries are fully charged you should show a red and green light on the charger. Now if you have a voltmeter plug the leads into the two outter holes of the charger port located under the front of the joystick.Without the charger plugged in you will be reading the battery voltage. Fully charged it should read 27-30 volts if you are only reading 20-24 volts then the batteries are low. If you have an onboard charger plug it in and you should read the charger voltage of 29-32 + volts If you aren't getting that voltage then you have a bad charger if you are getting the charger voltage then you have bad batteries and they need to be replaced Hope this helps you

My batteries are good but when i turn the chair on all lights come then go out leaving the two red lights flashing


Sonny you say your batteries are good but the error you describe indicates low batteries. If you have a digital voltmeter or can borrow one. set it to 200 volts dc and plug the leads into the two outter holes of the charger plug located under the front of the joystick. Fully charged you should be reading 25-27 volts, if you are reding less than 22 volts then the batteries need charging. Now with the meter still plugged in to the joystick plug in your on-board charger. when it is on and charging you should be reading anywhere from 25-30 volts. If you are not then the charger is not putting our the correct voltage and your batteries aren't getting charged correctly. After a full charge (the yellow light on the charger turns green) you should get 25-27 volts on the meter. If all of the voltages check out then you have another problem that I need more information to venture a solution Hope this helps you

I've been charhing the battery for 48 hours and no charge! any answers?


Kw How old are the batteries and have they been sitting up for a long time? If this is the case the charger cannot pick up really low batteries and charging them for 48 hours won't help. Unfortunately you have to get 2 new batteries. Your chair requires 2 U1 batteries. Now if the batteries are fairly new and when you plug the charger into the joystick you should be getting a red light and a yellow light on the charger. When fully charged the yellow light turns green. If you have both lights and it never turns green bad batteries if no lights or just the power light bad charger, If you have a digital voltmeter you can set it on 200 volts dc and place the leads in the two outter charger plug holes on the joystick. It should read the battery voltage fully charged 25-27 volts HOPE THIS HELPS

I have a jazzy power chair and when you turn it on all the lights come on for about 3 seconds then they go off and all you have is the red lights. we live in alaska so nobody around here to take it to


John Do the red lights blink or steady? this indication on the joystick usually means low batteries. Now this could be caused by bad batteries or a bad charger. On the jazzy if you have an on-board charger the light on the charger will come on green when the batteries are fully charged. If you can look under the rear of the chair you will see the charger and can tell if the light is green with the charger still plugged in after charging overnite. If the light is not lit then you probably have a bad charger. If you have a digital volt meter put it on dc volts 200 volt scale and plug the leads into the two outter charger port holes located under the front of the joystick. Your battery level should read 24-26 volts after charging all nite and with the charger plugged in up to 30 volts if there is no change in the voltage from charger plugged in and not plugged in then the charger is bad. You can then look to purchase an off-board charger that plugs into the joystick charger port to charge your batteries. If your battery readings are lower than 21 volts even after trying the new charger then you will have to replace the batteries. You might try to find someone in the local area that has an off-board charger you could borrow to see if you can get the batteries to charge. This will help you find out if the batteries need replacing. Hope this helps

Upon power up, 3 red LEDs flashing rapidly continously, no power.


The control systems on power mobility equipment have a "prevent" circuit that immobilizes the equipment while it is plugged into a charger, so folks won't take off with it plugged into the wall outlet. When you turn it on when plugged into a charger, the display will flash constantly, or sweep constantly, depending on the manufacturer. This is normal. Your off-board charger should have a red light to indicate power to the charger, and another light for the charge status. Yellowish means it is charging, when it turns green, you are fully charged. If the status light is green all the time, that is an indication that the charger is not functioning properly, or that the batteries are below a chargeable state. Check charger output, which should be 26-28 volts dc, and each battery should show at least a 12 volt reading, but around 13.5 volts with a full charge. If one or both of the batteries drops below 12 volts after a short period of time, it's time for a fresh pair. Fully charge new ones before using the chair.
