20 Most Recent Ryobi Two 18V Lithium-Ion Batteries + Lithium-Ion Charger Upgrade Combo Pack - Page 2 Questions & Answers

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.)

Go to the Ryobi website and find your answer. Which is better in terms of what? capacity, weight, cost, etc?

There could be a variety of reasons for the battery malfunction, some of which are listed below: a) low battery voltage due to long term storage without charging (>1 year, charger will not charge if the voltage is too low. What is the voltage?), b) cell imbalance due to shorting out the terminals (was the battery used for other purpose than running power tools?), c) internal corrosion caused by exposing the battery to damp environments during its life (need to open the battery and look for signs of corrosion on the cells. Was the battery left out in the rain at some point in time?), d) battery age, ie, the cells may have reached their end-of-life based on the number of charge cycles (what are the estimated number of cycles?), e) faulty charger (does the charger charge other batteries?), f) internal battery damage with broken connections (has the battery been dropped or mishandled at some point?). More details should be provided before suggesting possible solutions.

No, but the Lithium charger will charge the NiCads.

There is no such thing as a memory system in your battery. If you charge the battery until the green light on the charger comes on, that is as much as the battery can/will safely charge to. With Lithium batteries, they will fully charge whether they are at 75%, 50% or 10% capacity when placed on the charger and discharge to 0% if you use them that long. If you need the battery before the green light comes on and you use it, it will still fully charge when replaced on the charger. All batteries do discharge at different rates. Most not noticeably but a few will discharge fast enought to be noticable. If it affects your usage of the tool, you may want to exchange it or get it replaced under warranty because it will only get worse with age.

The batteries were discharged too low. A lithium battery should be recharged as soon as you see a loss of power.

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.

You are the thrid person in the last couple of days with this same problem and i check who was posting the problems all differant people all RYOBI 18V lithium-ion batterys and they all got them for christmas. SOMETHING is not right there is now warranty on the batterys but there is one on faulty workmenship there must be a problem with this type of battery good luck

The battery problem, buy new Ryobi batteries.

They are real Ryobi packs but are said to be used/rebuilt from warranty returns. Forum users have posted that they typically do work, but can be in very rough condition and may have off brand or used cells inside. Better to spend the money and get new ones when on sale.

I know this is an older question but I would not recommend using these batteries for your inverter. While they are powerful for their size, LiOn batteries require careful metering and control of both charging and discharge cycles and do not last long if fully discharged (IE: running an inverter until they are dead). You would get much better performance from a deep cycle lead acid battery, which is designed to be discharged fully. If you were to use the drill batteries for your project, you'd want to get someone with electronics experience to wire a connection to the Ryobi charger to accept the lower voltage input from the solar PV (instead of 120V) so the charger can regulate the charge rate. You'd need to make sure the solar panel voltage is within the same range as the charger's low voltage side (never tested, but guess around 20-24VDC). In addition, you'd need to make sure the inverter is monitored and turned off before the batteries shut down (their internal circuit protection shuts them down around 10% IIRC). Don't rely on the battery to protect itself, that is a sure fire way to ruin your batteries (no pun:-). Hope this helps.

Mike, Would need a bit more detail to give the best answer, but here are some general tips to point you in the right direction. Need to know if you get any LEDs on the charger or batteries, do you have other batteries you can use to test the charger/tool to isolate the problem (even the old NiCads)? Does this problem occur with one or both new batteries? Anyway, read below for some suggestions:Lithium Ion batteries do not like to be fully discharged even if they are new. If you ran a tool until the battery fails, two problems can occur. 1. The circuitry in the charger and the battery itself senses a fault due to "too low" voltage in the cells, and prevents charging as a protection measure (prevents overheating a shorted cell). 2. You damaged the cell(s) inside the battery either due to sulfate build up or heat. If your Ryobi charger is flashing a red LED (no green) indicating battery fault, I have found that removing the battery and reinserting it multiple times can help as the charger does a diagnostic when you first insert the battery. This test likely applies a small charge to the cells and analyzes the response, if you do the test enough, it can bring the cells back up to a sufficient level to allow the charger to accept it. If the battery charger cycles normally but displays a full charge very quickly, the battery may be defective and not pulling any current from the charger, so the charger thinks it's fully charged. If the battery charger does not sense the battery at all (no LED display) then the problem could be a defective charger, defective (open) battery or corroded/dirty connections (make sure no paint or dirt got into the charger port and no rust on the contacts).

p103 is name of the battery. p106 is the kit with 2 p103 batteries. same thing just 2 times. the p104 however is bigger and holds more juice.
