Exactly what it's supposed to be

  • Familiarity: I've put it through the wringer

Well built, functional, and does what it's supposed to do. With the standard etap charger, this battery charges up quickly and holds a charge for a surprisingly long distance/time. I've got 3 bikes outfitted with eTap for a total of 6 batteries in operation at any given time. So far this year, I've ridden about 2500 miles and have only charged the batteries a couple of times. Even then, they weren't showing low charge, I just charged them on principle.

If you need an eTap battery as a spare, get one. It's a reasonable price. Keep a spare in your car so if you forget your batteries on race day, at least you can work your way through the rear cassette in a race.

Broke

    Both batteries broke after a few normal rides!

    A little more detail would be helpful. I have 3 sets of eTap on 3 different bikes and have had zero problems with battery breakage. I'd be curious to know how you could even break these.
