"What are the red things?"
When you picked up your new bike at the shop and the mechanic handed you a bunch of red plastic pieces, you might have tossed them in the junk drawer. These are actually important little bits called battery terminal covers and battery blocks. When you remove a battery for storage, cleaning, or travel, you'll need both of them. These protect and preserve your batteries and components when they are not in use.
Tech tip: Use the adjustable dial on your battery cover to help you remember a battery's charge level.
"Do I need to stick with the SRAM brand?"
While inexpensive generic options are tempting online, they are not worth the risk. These copycat batteries and chargers do not hold up to SRAM's performance standards for capacity, safety, and reliability. Genuine SRAM parts are designed and tested with a priority on safety and optimal performance. Avoid any other manufacturer's offerings, as using them will void SRAM's warranty.
We have compared the copycats to the real deal and found plenty of reasons to beware of these off-brand batteries and chargers:
"What about the batteries in my shifters?"
Each AXS shifter uses a CR2032 battery. These coin cell batteries last about two years under normal use and are easy to replace.
Tech tip: For best performance, choose replacement batteries without a bitter child-safe coating ring. This ring can cause interference between the battery and terminal, resulting in potential perfomance issues.
"What kind of battery is in my power meter?"
AXS power meter spiders also use CR2032 coin cell batteries. These last for 200 ride hours, and require no tools to swap. Again, choose one without the child-safe coating when it's replacement time to ensure your power meter performs as optimally as possible.
If you have a spindle-based power meter, you'll get 400+ hours of ride time from the AAA lithium battery inside the battery sled.
