It is what it is, a must for AXS components and saddle bags.

A must if you run Axs components and having one in the saddle bag is also a must. Yes if you run a 2x then you could always switch but not many bikes these days run 2X So I keep one in the saddle bag for those special occasions.

Spare eTap batter provides assurance

We recently got a new tandem bike with the SRAM eTap drivetrain. We absolutely love the new system, with just one chainring and 12 gears, ranging 10 - 52. The battery charge is supposed to be good for 25 hours, but we decided it would be a good idea to carry a spare battery during multi-day bike tours. The spare battery is small and easy to carry in a bike bag or pocket of a hydration pack. Glad the Bike Tires Direct had it in stock.

SRAM eTap Battery

I carry an extra battery with me when I ride. My front deraileur battery lost power on a ride and if I had the extra battery it would have been an easy fix. Small and light weight, just add it to your saddle bag.

Well worth it to keep an extra battery on hand

SRAM advertises that these are supposed to keep a charge for a very long time but in my experience i'd rather not be stuck in a certain gear so i'll take the weight penalty and keep this with me

Easy to use. Good to have a backup battery.

An inexpensive way to ensure your MTB is fully charged and ready to ride. I keep a spare battery in the charger so there is a fully charged unit when needed.

It's a bloomin' battery for the stupid derailleur.

BTD insists that I file a review for a SRAM battery. So here it is...

This battery doesn't make anything special happen. It doesn't win friends or influence people. This battery (#3) just sits in my saddle bag waiting for Battery #1 or Battery #2 to die. Since I now have a spare, I expect I will never experience a dead battery out on the road. If I didn't buy a spare, #1 or #2 would die 40 miles from my house on the rainiest coldest day of the year.

That's how good this battery is. It sits in my bag and wards off death of other batteries.

SRAM batteries have always been super reliable for me. Getting them through BTD is an added bonus of convenience :)

I ordered this as an extra for bike packing. Super easy to throw in a pocket to be sure youre never left without shifting or a dropper post.

Long-lasting power and relatively durable

The Sram Red eTap batteries hold a charge for many rides (I think Sram notes that they should last 600 km and I think I've been able to exceed that) and they have survived for a couple of years of hot summer and cold winter riding, much of which was on chipseal roads. However, recently I've had to replace a couple of them as the tabs that fit into the slot on the derailleur have broken off, no doubt due to the extreme temperature changes and the vibration caused by the road surfaces. It is also important to remove these batteries when traveling long distances with the bike on a bike rack as the derailleurs recognize the motion and keep the units on which will discharge the batteries.

Back up battery

My current bike has sram batteries. On a minimum of 2 occasions I have had my battery die on me due to my forgetfulness to keep them charged. So I purchased a "backup" battery to keep in my saddlebag for those moments. It also helps me to remember to charge my existing battery!

Battery tabs keep breaking

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.

reliable battery with fragile plastic tab

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.

Super long lasting!

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!

Only product that powers the etap derailleurs

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.

The right battery but expensive

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.
