They come in all shapes and sizes, are energy-dense (hold a lot of energy), have a higher voltage than NiCad or NiMH batteries, and can withstand high amp draws. In most cases I rarely if ever use the corded tools they replaced, despite this there does seem to be a major week point, the batteries. Is this what RYOBI recommends? This should take around 3 hours depending on what type of Li-ion battery you are reconditioning.

Now as a safety feature, most of these chargers will not charge a cell under that 2.6 to 2.5 volt range, but there's a workaround. I measured it after I dissected it and it was a pretty-much-dead 5.6 volts with each cell reading around 1.8 volts. Release the clamps and check the charge level on the battery using the battery tester. About: I love scrapping and dissecting electronics and taking out the guts to see all the goodies inside. Turn on the charger and allow it to charge. Let them fully charge, and take them off the charger. The cells were badly degraded and their capacity was down to just 550 and 660 mAh fully charged, down from their 1500 mAh new capacity. However, this could reduce battery life on newer lithium ion batteries, so for those batteries it’s suggested you only let the battery level drop to 35% to 45% and then charge it back up to 75% to 85%. Always start at the lowest charge current possible. If you aren't getting anywhere, go back to the knife and repeat the first step. Using any other charger could cause the lithium-ion cells to overcharge and result in a fire.
