750 kilometers between charges sounds like a number Campagnolo pulled from a marketing hat until you realize that's roughly a month of riding for most serious cyclists. The Super Record 13 Derailleur Battery delivers enough range that charging becomes a weekly ritual rather than a daily chore, and when you do need to top up, the 60-minute full recharge means you can plug in during dinner and ride the next morning with a full tank. That practical approach to battery life addresses one of the persistent anxieties around wireless shifting: nobody wants their rear derailleur to die mid-climb because they forgot to charge.

This battery set includes both the front and rear derailleur batteries, which are position-specific and not interchangeable between derailleurs. Campagnolo designed each battery to integrate with its respective derailleur housing, creating a cleaner visual profile than competitors whose batteries hang off the back of the mechanism. The front derailleur battery weighs 34 grams while the rear comes in at 38 grams, with the slight difference reflecting the different form factors required for each mounting position. You cannot swap a depleted rear battery with a charged front battery mid-ride, so monitoring both charge levels through the MyCampy app or your bike computer becomes part of the pre-ride routine.

Charging happens through quick-snap magnetic ports that work whether the batteries are installed on the bike or removed. The magnetic connection means no fumbling with small plugs or worrying about port alignment in low light. USB-C cables handle the actual power delivery, and Campagnolo built in reverse charging capability that lets you use a smartphone as an emergency power bank if you find yourself stranded with depleted batteries. That's an edge case feature, but it's the kind of detail that suggests Campagnolo thought through real-world scenarios beyond the laboratory.... Read More
