“60% in the App but My Garmin Says Low”: WHEELTOP Battery Questions
Charge life, the one magnetic cable, a battery you cannot take out, CR2032 coin cells, and what to do when the app and your bike computer disagree.
Battery questions pile up in the same few places: how long a charge lasts, whether you can swap the derailleur battery, and why the app and a bike computer don’t show the same number. The shift-count page WHEELTOP wireless derailleur battery life is the companion to this one. The short FAQ is how long the battery lasts, and how to charge the EDS TX.
How long a charge lasts
The rear derailleur has a built-in 800mAh / 7.4V / 5.92Wh battery, rated for about 20,000+ shifts per charge. The front derailleur has its own 500mAh / 7.4V / 3.7Wh battery, built into the front derailleur. The OX 2.0 listing states up to 24,000 shifts per charge. As a riding guide: about 200 km a day is roughly 10 days between charges, and about 20 km a day is a bit over a month.
Riders also ask how that compares with a SRAM Force eTap AXS battery. We don’t have a side-by-side test, so we don’t publish a winner. The figures above are the ones we can stand behind.
Charging
Charging uses a magnetic pogo-pin cable. Open the dust cover and let the plug snap on. The charger should be USB 5 V, at under 2 A. A red light means it is charging.
One cable is all you need. Charge the front and rear derailleurs one after the other. They don’t both run flat at the same time, so you never need to charge them at once. Factory kits ship with one magnetic cable.
Can I replace the derailleur battery?
No. The derailleur battery is built in. It is not a quick-release pack, and it does not come off for you to swap. If you need a repair, email support@aoeagle.com for a quote. We don’t list a price for that job.
Shifter coin cells (CR2032)
Each shifter uses a CR2032 coin cell. You change it without tools. On the OX shifter, a coin opens the battery cover. One cell typically lasts more than a year.
Standard vs Racing mode and idle drain
The kit starts in Standard mode. Racing mode is a switch in the app. In Standard, the derailleur sleeps when it sits idle, which saves power. In Racing it stays awake, answers fastest, and resists interference.
A slow drop while the bike sits unused is normal. Sleeping is not the same as using no power. Charge it when it is empty. That idle drop is not a fault.
App vs head-unit readings
Over ANT+, the system sends the gear and the battery level to a bike computer. Riders do see the two displays disagree, including a low-battery warning on the computer while the app still shows a higher percentage, and coin-cell voltage that moves between app restarts.
We don’t have a published reason for that difference, so we won’t invent one. If the two readings are far enough apart that you don’t trust either, email support@aoeagle.com and tell us both numbers and which computer you use.
