SRAMeTap / AXS Battery(Return to Product Page)

Bought as a gift for someone who appreciates having a spare.

No matter what I did, the tabs on my eTap batteries would crack, break and would eventually fall. I went through 10 of these batteries on 2 different bikes.

Tried to use electrical tape where the plastic comes in contact with the metal part on the derailleur, tried glue as a preventative measure, tried to avoid any bike cleaning products, but I always ended up with using rubber bands to secure the batteries, because the tabs would break.

The SRAM Red eTap system is terrific and the battery can power things for quite a while between charges - if you run down in the rear, it just takes moments to swap with the front to finish your ride BUT the plastic tab on the battery is fragile and can chip or break off so be careful when inserting the battery into the bike or charger - a small 'price to pay' for an otherwise wonderful shifting system.

Good deal

These batteries and the efficiency of the SRAM Electronic shifting system is impressive. I use mine on a new AXS system. I keep a spare with me on all of my longer rides but Ive never had to use it. Im pushing 50 hours of riding on the last full charge and all lights are still green! No complaints!

Easier shifting when on the drops.

This is the only battery of SRAM Red eTap deraillieurs. The battery works well, but the tab securing the battery to the deraillieur is fragile.

Expensive but on a very light XC racing build this is key. Super reliable. Long life and an extra battery is just insurance in a long race.

it's a battery. you need it for your etap groupset.

Battery went bad after 1 week. BikeTiresDirect was great and sent a new one within 3 business days

I purchased a 'spare' battery in the event that I ran out of juice and was unable to shift. I'm very pleased with the performance and would definitely recommend them to others.

SRAM front and rear derailleurs don't come with batteries most of the time. I converted my TT bike from mechanical to wireless shifting and needed one more battery to complete the set up. It's nice that these are standard and can be moved between bikes so you don't need to have a bunch of them. I have another one on my AXS XPLR dropper post that I move to the TT Bike when I'm going to ride it now, or back when I'm using the gravel bike.

I got another battery for when I go for some really long rides up in the hills. Just a peace of mind purchase an easy charge too.

The only weak spot, as mentioned numerous times, is the tab holding the battery in place. Use super glue sparingly to repair. Has lasted several years on all three batteries.

I've never had a battery on eTap run out of juice on the road, but with some longer multi-day tours coming up (with no easy access to recharging), a spare seemed a good idea. I also carry an extra pair of CR3032 button cells just in case a shift lever battery goes out.
