Running the 12-speed Di2 in full wired increases the battery life by 50, so if you ‘re into bikepacking, decidedly consider doing that. Shimano claims a battery life of 1000km for the wireless Di2 groupsets, or about 1200 front derailleur shifts, and 8200 rear derailleur shifts. however, barrage life has decreased slightly compared to the 11-speed groupsets. Wireless transfer, and pretty good battery life.
Shimano di2 battery status update#
This update enables Edge devices to receive Shimano Di2 12-speed data. This is said to deliver the best of both worlds.
Garmin rolled out 12-speed support for eTap a couple of years ago, so those user interface parts were reused. Connect the magnetic end rear derailleur. Pop open the charging port on the rear derailleur by placing your finger on the notch. Connect the USB-A end to a regular smartphone charger with at least 1.0A capacity. This is a huge hurrah, because I have been burned a couple times when I forgot to replace an eTap shifter battery. The 12-speed Shimano Di2 uses an internal battery (BT-DN300) and requires the EW-EC300 charging cable. The mountain bike Di2 systems offer a handlebar-mounted digital display, which actually gives you a double beep when you’re about to get a double shift like the Garmin, it also displays M, S1. And it is on the Gear Combo field with appropriate options for 12-speed cassettes.Ī quick note for the eTap folks… yes, the battery data fields apply to eTap and other ANT+ shifting sensors as well. This shows up on the “Gears” field that has vertical bars to represent the active front & rear gear. The new update also presents front and rear gear data for 12-speed Di2 gear systems. However, it now shows status for all batteries (each shifter and the main frame battery), so overall it is giving us more information. Some Slowtwitch readers noted that they lose granularity with the new battery bars versus percentage visualization. It was not so great for eTap users with 3 or 4 batteries. When I hold one of the shifters down, the battery life indicator light comes on and holds steady green for about 2 seconds, but immediately after the green light goes off, the adjustment light right next to it flashes red for about a second. That worked great for 11-speed Di2 because it had only one battery. Shimano ‘s 12-speed semi-wireless Di2 groupsets feature wireless shift. I have a new bike with the Shimano Dura Ace 9070 Di2 groupset on it. The old Di2 (and general Gear) battery fields just displayed a single composite battery level. Garmin introduced a new Di2 Battery field that can now show multiple battery status levels. This was part of a rollout for full 12-speed support that arrived today for Edge 530, Edge 830, Edge 1030 and Edge 1030 Plus head units. A couple of weeks ago, a few eagle-eyed Slowtwitchers noticed that Garmin changed the Di2 battery field after an Edge 830 firmware update.
