although i'm blown away by how long the early charges last (but fade a bit over repeated usage), it can jar loose during normal sweeper usage. there's a little raised bump that isn't raised quite far enough to keep the battery stable and its electrical contact secure, making its operation "cut out" at times. i've devised a workaround by drilling a tiny hole next to the bump and installing a screw that raises a tad higher; this has worked and been necessary for 2 of this brand batteries on my eureka sweeper.
i only trust oem printer cartridges after several unsatisfactory experiences w/knockoffs. this one fulfilled expectations.

i guessed right
not a bike-mechanic per trade, but i guestimated right on this one. combined it with spacers to offset a single front chainring to center it, keeping the chain in place and as quiet as possible across 9 rear gears.
