How long does it hold a charge if I keep it in my bag as a spare?

(Perhaps overly detailed answer). I charged two of these batteries and a genuine SRAM one at the same time. I got 18 hours of riding out of the SRAM one over a 5 week period. Then I put in an MRX (5 weeks after charging), and got 12 hours over 4 weeks of riding. Then I put in the second MRX (now 9 weeks after charging) and got 8 hours. So, they seem to hold a charge well enough to use as backup.

Is this battery compatible with the sram etap charger?

I believe it’s the same charger for AXS and etap

What is the warranty on these batteries?

I don't know but for the money, just buy it. I haven't noticed the difference between it and the SRAM battery.
