No more dead battery at the ride start

Started happening that my battery would be dead at the start of a ride. I thought it might have been laying against the shifter, but it happened three times. Time for a new battery and that solved the problem. Plug and play and it holds a charge like when it was new. Only 6 years old and 15,000 miles but it was this battery’s time.

Easy swap-out and upgrade

Familiarity:
I've used it several times

After 7 years it was time to repalce my battery. Shipping was fast. The BT-DN100-A also provided the upgrade to allow me to add the wireless module as well. All was seamless.

On my road bike, I have a Shimano Alfine internal gear hub, 11 speed for a 1 x 11 setup. I got the Di2 motorized shifter for it and use this battery to do the shifting. After some rides around my home for most of a summer, I rode this bike along the Pacific Coast from Canada to Mexico in the fall of 2019, immediately pre-covid. The shifting and charging were flawless. Indicator lighting works properly, and only once did I run out of juice so was locked into a gear with no means to change it. I'm thinking about 7 to 10 thousand shifts per charge. I have a front dynamo hub and was able to charge the Di2 battery while riding for the rest of the day and all worked out just fine. Good system, Shimano.
