Ryobi P115 is an 18V battery charger. However, Ryobi Manual did not mention the current rating of P115. if the current rating of Ryobi P115 is 50% higher than your 18V Lithium Battery it will charge. but if it's less than or equal, it will not.
No, the P110, 18V NiCad battery charger, will not charge a 18V lithium ion battery. You need one of the dual-chemistry chargers. If you have the Ryobi ONE+ batteries, you can get the P117 charger ($30) or a charger with an extra battery (P126) from a store like Home Depot. A 6 battery charger and a 12V in-car charger are also available.
I wish that I had better news for you.
Cindy Wells (who has the Ryobi 12V drill and charger, a few of the 4V tools, and a number of the ONE+ 18V devices and chargers. The single chemistry battery charger is not used much any more.)
The physical differences between two models of Ryobi batteries is: - The P103 (Part Number 130429008) is a 1.5 Amp/Hour (a measure of how long a battery lasts on a charge) battery. If totally discharged it takes about 15-20 minutes to charge back to full. It is lighter than the P104 because it has half the cells inside. Lighter, quicker to recharge, quicker to discharge, shorter lifespan. - The P104 (Part Number 130429017) is a 3.0 Amp/Hour battery. It takes about 30-35 minutes to charge it to full if fully discharged. Slightly heavier, longer time to discharge & recharge, longer lifespan. Considerations: - No difference between batteries in the performance of your tools. - The number of times you discharge and recharge a battery determines a batteries lifespan. That's why most manuals will tell you to fully discharge a battery before putting it on a charger. - If you only have one battery you cannot use your tools while it is recharging. On big projects you have to have two batteries. - The weight difference between batteries is negligable unless you are working with the tool in your hand for extended periods.
I use the Ryobi Li-Ion tools the L-I batteries will cut off when they get to a low charge level this is to protect the batteries Li-Ion batteries life span is shortened when fullt discharged so when the tool suddenly stops put the battery on charge,also if the battery has a charge indicator light for a more accurite idea of the charge (green is charged,red discharged) hold the test button on then run the tool the light may go from green to red if it does that shows the the charge is about depleted if the light stays green you have a little run time left.
Batteries must be completely dead before recharging or battery life is shortened.large battery is probably defective contact Ryobi to replace battery they while probably send you new batteries for free if you tell them you are going to stop buy their products.Tell them about both batteries they will probably replace both for no charge
That is true the One+ 18V Li-Ion battery packs will work in any One+ 18V Ryobi tool. However the Lithium ion batteries will not charge in the original P110 NiCd charger. You will need one of the the new series Ryobi One+ 18V "dual chemistry" chargers for that. The will charge both types of battery packs.
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.
If both batteries won't hold a charge the problem may be the charger (not providing a full charge). If one battery is OK and one not holding a charge, the problem is probably a defect with the battery. I know there expensive, (I recently had to replace one for DeWalt).
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.
No, just return it, for the money they should give you one that works. It is common to get a defective Ryobi 18v lithium battery. I've had 2 out of 7 purchased that wouldn't hold a charge. But when you get a good one they work awesome!
