I took the battery out of my V3 (not supposed to leave it long term) and put it in the charger. The charge light would not light up. I put it back in the V3 and turned it on.. still had 9.3 volts. Checked the second battery, no problem, charging light lit right up. I called White's customer service, described the problem, and without even any questions, they took my name and address and said we are mailing you a new one. WOW!!!!!! I knew they were good, but this is awesome. Thank you White's Electronics. RickO
