New battery, with mini screwdriver. Exactly what I wanted.
I found Headset Advisors thru a YouTube video they made which showed me how to replace the battery. Ordered and received the battery but it would not charge. Spoke with customer service and they shipped out a new one that worked great. They're good people!
Batteries seem to work great and installation is super easy!
Looked everywhere for this battery and it only took 4 days to get this all the way from Cali to St. Louis MO. Thanks for the speedy delivery!!
