This battery is a high-capacity replacement for the newer version of the Waterpik WP-450 Water Flosser that was fitted with a side-by-side battery pack, plus some other models such as the WP-360. Older versions of the WP-450, WP-360 and some other models were fitted with end-to-end battery packs so open up your Waterpik before ordering to double-check your original battery dimensions.
The fitted solder tags will need trimming to length/shape with scissors to fit your appliance and may need to be folded back on themselves to reverse the polarity to match the +/- connections on your appliance. See our battery pack polarity reversal page for instructions on how to do this.
Also replaces certain original Waterpik batteries and shaver/trimmer batteries of the same dimensions with some of the following markings, and others.
