I was about to toss my toothbrush when I came across Ionic! I never could have done the installation without the very clear illustrated directions. It took me about 30 minutes to remove and replace the battery. The battery arrived here (California) faster than many things shipped from within the US.

I ordered two batteries to replace old in my 3756. Delivery to Georgia, US was on time. I followed the how to guide here. It took me 30min -1 hour to replace first one, but second one went really quick. After charging new battery, it holds charge like new one. Thank you.
