Hi Florin, Thanks for your question on the RYOBI 40-Volt Lithium-Ion Rapid Charger OP406A. When the red and the green LED's are flashing that is usually a sign of an error on the battery pack or charger. Try to repeat the conditions a second time by removing and reinstalling the battery pack. If the LED status repeats a second time, try charging a different battery. If a different battery charges normally, dispose of the pack that received the Error (see your battery pack manual for instructions). If a different battery also indicates Error, the charger should be replaced. Thanks for asking! - Eve
Not sure what to tell you exactly on that one. . . make sure there is nothing that fell in to stop the battery from going all the way in. . . or maybe send it back, or call Ryobi or Home Depot. . . Mine works great. . . sorry I can't be of more help.

While it is possible to power this RYOBI battery charger with an inverter, a cigarette lighter receptacle will not power an inverter large enough to supply the RYOBI battery charger. Most cigarette lighter receptacles are protected by a 15-amp fuse, very few will be protected by a 20-amp fuse. Even with the engine running, the alternator producing 14 volts, and a 20-amp fuse, it will only supply (14V x 20A) = 280 watts. Most inverters are only 90-percent efficient. The Ryobi battery charger has an input rating of 295 watts. The maximum current draw of an inverter will be approximately 325 watts and would melt a 20-amp fuse and melt a 15-amp fuse much faster. It would be best to connect the inverter directly to the battery or install a 30-amp circuit for the inverter. If using an inverter, I recommend using a true-sinewave inverter over a modified square wave inverter, as the charger could operate warmer or potentially overheat on choppy square wave power. The car battery will not be damaged by an inverter. Most inverters shut down at 10.5 volts, before battery damage can occur. However, the battery may not be able to start the engine if discharged to 10.5 volts. And the battery should be fully recharged as soon as possible. However, if running the engine, most car alternators will supply the inverter and not drain the car battery.
This will not damage your battery or charger. Especially if you are using it a couple of times per month, then it will definitely not damage it. What you would need to do in order to get the most amount of life out of your batteries, will be the same as any other Lithium Ion battery. Off the top of my head: If you are not going to use the battery for several months, the battery might last slightly longer if you store it off the charger which will let it naturally self-discharge a small bit and rest in that partially discharged state. To get optimal battery life, the Ryobi booklet prescribed a regiment of storing it half-charged and periodically charging it and then discharging it to half-charge. This seems like more work than anyone is actually going to do.
The RYOBI Rapid Charger has an input rating of 295 watts. At the bare minimum I recommend using a true sinewave inverter of at least 400 watts. I never like operating anything near its peek limit.
It has a two prong plug I’m not sure about the electrical pull. I have an old house with old electrical and it seems to do fine
The RYOBI Operator’s Manual does not list a boost mode or the ability to recover damaged batteries. The RYOBI battery will stop operating at a safe discharge level. If recharged soon after the battery has been discharged it should not go to sleep or in a dead state where it cannot be recharged. The RYOBI charger will attempt to condition a deeply discharged battery to a high enough voltage to be recharged. If the charger fails to condition a deeply discharged battery after two attempts, the battery may have reached end of life. This type of damage usually only occurs when an exhausted battery is placed on the shelf or left in the tool in a discharged state and further self-discharges over time. If even one cell as gone into protection mode due to deep discharge, the battery may have to opened to potentially recover a cell that was disabled for safety reasons as applying high currents and voltages to a Lithium battery can have disastrous results.
Yes and it automatically goes to sleep after a period of inactivity.
