Why We Like The Di2 Internal Battery Charger

One of the most common concerns with the Shimano Di2 electronic shifting system is, of course, what happens when the batteries lose charge. Fortunately, Shimano has the answer. It's called the Shimano Di2 Internal Battery Charger. With a charge time of just an hour and a half, you won't ever miss a ride because of charging.

The charger is made to accommodate both internal or external battery systems by connecting to the SM-EW90 junction box. The charger also has two indicator lights—one that tells you when it's charged or charging, and one that tells you if there is a problem with the battery or system.

The Shimano Di2 Internal Battery Charger comes in one size and in the color Black.

Too expensive!!!

I've used it several times

This is a Shimano OEM part and works as flawless as any other part they make. That said, there is NO reason a simple battery charger should be $130!!!! This comes off as Shimano gouging their users with a proprietary product.

Works great

I've used it several times

This is the cable you need to connect the system to the laptop. A must have for firmware updates. Works good.
