    Running an electronic drivetrain isn't technically cheating, but super-smooth and reliable shifting might make you feel like you're doing something a little illicit. Don't sweat it, though—the haters are just jealous. The only drawback to electronic shifting is the possibility that it'll run out of juice and leave you stuck, but Shimano's Di2 Battery puts an end to your drained-battery worries, with an average life of 1000 miles. A battery life indicator is activated by depressing the shifter paddle for a few seconds, and displays flashing or solid red or green lights, depending on the remaining charge. The Di2 charger (not included) fires the battery up to full charge in 1.5 hours, and the battery will charge about 300 times before you have to think about replacing it. Shimano also hooked the Di2 up with a sturdy and convenient bottle-cage mount to secure it to your bike, and built in a sleep mode to save battery life when you're not shifting.

    Works as OEM, cost more than my car batt

    • Familiarity: I've put it through the wringer

    I lost my initial battery after about 500 miles on a rough road. I bought a replacement and it has worked just as well. I charge it about every 500 miles.

    I would give this product a 5* except for the pricing. My car battery costs less. This is shimano charging a price premium for their branding.


    • Familiarity: I've put it through the wringer

    My initial battery life was exceptional. However, once it was depleted it fails to hold a charge for more than 75-100 miles. It has become routine for me to spend significant time during my rides stuck in whatever gear I was riding when the battery died. This happens despite showing green on the battery indicator light at the start of the ride.
