20 Most Recent Ryobi Multi-Volt Battery Charger - Page 8 Questions & Answers

Its likely the batteries will take at least several hours to fully charge, if not more. NiCad batteries are slow charging and usually need 4-6 hours for a full charge. Keep them on longer or even overnight but make sure you remove them in the morning. You will probably find the light turns green after 4-6 hours of charging. If lights stay yellow and green after 12 hours of charging, it may indicate a fault in the battery itself where it will not accept a charge.

Yes you can replace the inside batteries yourself , just take the old ones out and go to Battery world or a similar shop and get replacements then all you have to do is repack them yourself and put them back into the battery case .

Absolutely not. The risk of damage to the battery is only a minor concern compared to the fire hazard you would be creating.

Did you wire them in circuit? (hot lead to positive on 1st batt, which jumps to the neg on 2nd batt, and neg lead going to neg post on 1st batt, then to positive on 2nd batt) That would be for a 24v system, for a 36v you would continue to the opposite posts again.

Hi,
your NG3 should have been preprogrammed for the type of batteries you are charging. The NG3 has the 3 wires from the power cord. Here is what I have done:
Brown from charger goes to black wire
Blue goes to white wire
yellow green goes to green ground.

Negative partner, you can try all day everyday but 12 v is 12v and 18 v is much more. its just not gonna supply enough juice to charge the battery. the most youll ever charge it is 12 v... sorry.

i have a manul that you can fix all your batterys ,very easy email me i will send you the file cheers at [email protected]

Had the same problem with some makita batteries, Was going to throw them away so decided to take apart and see what was happening. The are made up of 1.5 volt cells soldered together, found that many had .9 volts or less and others had 1.5 or more. This means that some of the cells had gone bad (probably due to lack of chemical reaction). Found that if I collected all of the 1.5 volt together could charge just fine. Problem is it is very hard to get them all soldered back together and even harder to enclose them. If a mfg. could come up with some way to change cells individually they could make a lot of money and save us a lot. So the answer to your question is buy you at least one more battery and recycle your old one.

Then unfortunatly your battery charger is faulty and has to be replaced. If the unit is under warranty a Ryobi service center will be able to supply on free of charge.

you need to go to a **** smith store and bye a kit to do this cheers peter

Either the battery is hot from use or has been in the sun, let it cool down, then try again.

you need to open up you battery and check each on for voltage. take out the ones that have no voltage and resolder it with the good battery from your other non working one. you need to ruff up the top and bottom of the battery to solder a wire to it. make sure you dont touch the battery to the wrong polarity or you will get a spark or fire.

Just got a reply from Ryobi tech service and it says that "all Ryobi 18V platform power tools can accept and use the lithium batterys, but you must use the charger for the lithium to recharge them. Hope this helps. Dave

You don't need help, you need patience. That charger is on a timer. You can probably use it now anyway. If this is helpful, please post as such. TY

if it's a different model - however, most models are the same

I have two 18volt chargers doing the same thing. I have had them apart and it seems to be the transformer not pushing any power thru. If you can find a transformer that fits and has the right voltage that should fix the problem. From what I can make out if you leave the battery in for too long on charge it cooks the transformer. Hope this helps

Ryobi web site lists the new part numbers for consumables, but by saw model
go to
https://www.customernation.com/pls/ps/ps.ps_main?p_host=329&p_supplier=5060&p_parm=PSHPP
and put in the model number of the saw, and it should punch out current part numbers

unplug saw
new Ryobi have a spindle lock button, it is unobtrusive and you may miss it
If yours does not, secondhand etc, a screwdriver in the blade teeth between the upper and lower guards provides a locking bar enough to undo the arbor bolt
