just got a max 20V drill & driver kit with two 20V max 1.5 Amp batteries. batteries were charged and lasted a long time. They now need charging. the DCB101 charger shows slow blink in charging and solid when done on both. Batteries are only charging to 14.4V (B- to B+) on both, and do power to drive drill or driver. Charger says 12V/20V. is there some switch or something that must be set to charge the 20V to full 20V? Both batteries are new and no failures are indicated on the charger blinking light. I love the drill and driver when they work (great power), but am now frustrated
Thanks for your help
