The tool uses only 4 pins: A, B, D, and E. It does not connect to pin C which has a voltage on it. The charger also only uses 4 pins, but it uses pins: B, C, D, and E. It does not use A which I measured as the largest voltage. Thank you for any information you have on the pinout of these batteries. A Designer's Guide to Lithium Ion (Li ion) Battery ... If the charger is left connected to the battery, a periodic ‘top up’ charge is applied to counteract battery self discharge. The top up charge is typically initiated when the open circuit voltage of the battery drops to less than 3.9 to 4 V, and terminates when the full charge voltage of 4.1 to 4.2 V is again attained. 18V ONE ™ COMPACT LITHIUM ION BATTERY | RYOBI Tools This new battery provides up to 20% more runtime, holds a charge 4X longer and is 45% lighter weight than 18V ONE Ni Cd batteries at exactly the same price. Best of all, like all 18V ONE batteries, these new lithium ion batteries work in every RYOBI 18V ONE tool ever made.
