Value depends on how long they last! 22 February 2018
I've had my water jet for 4 years and just got around to replacing the original batteries (200 weeks, less than 100 recharges). I have always run the irrigator until the batteries died and then recharged them fully. Replacing the batteries was fairly difficult, perhaps because joints had become a bit clogged up over the years. The top cover has a small slit for a screwdriver blade, but I had to use more strength than I wanted to to get it off. I thought I would break something. The batteries, motor etcetera were stiff to remove, and also needed a strong push to refit them. panasonic.com has downloadable manuals so you can find an exploded picture (number 14) showing how to get at the top screw. At the time I looked, the only options were manuals in Croatian or Serbian - no English!
