What is a Li Ion battery? Li ion batteries are mostly used in cell phones, laptops, surgical devices etc. It uses Graphite rods as Cathode and Lithium Oxide as anode. What causes it to age? The battery works on the principle of movement of two electrodes. However, with time, elevated temperature and prolonged cycling, the performance reduces over time.

If the battery reads below 12 volts, it’s considered “discharged.” Driving around can’t revive a battery below 12 volts, and attempting to do so might damage the alternator.
Step 10. Test your the voltage on your battery pack again. It should be higher than it was before boosting. (Again, if you don't have a multimeter don't worry about this - you'll just have to press on without one)
The corners of the adhesive frame are different and will help you align it correctly with your device's frame.

Since originally posting this tutorial a few years ago I've been hoping Ryobi would improve their batteries and chargers. So I was happy to see the development of the newer Ryobi P117 Intelliport Charger. It's supposed to do a faster and better job of charging your batteries but according to the reviews on Home Depot and Amazon they don't have this issue figured out quite yet.

If you have any sort of cordless power tool, but especially one powered by a Ryobi 18V battery, you have no doubt encountered the dreaded flashing red charger light. And if you haven't ... you will. It inevitably goes like this - you run to the basement to grab your cordless drill because after 10 years of thinking about it, you're finally going to build that 4 level, Tudor style treehouse with kitchenette. Or you're going to hang a picture.
