Review by Greg L. RoweReviewed 8/4/2023by Greg L. RoweCycling EnthusiastDavis CASpare eTap batter provides assuranceWe 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.

Review by ApassdoreReviewed 8/31/2023by ApassdorePortland, OrEasy 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.

Review by Robert StrobelReviewed 6/20/2023by Robert StrobelCompetitive RacerBoulder, COSRAM 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.

Review by AnonymousReviewed 2/10/2023by AnonymousEverett, WA1 of 1 customers found this review helpful.Well worth it to keep an extra battery on handSRAM 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

Review by American ProReviewed 5/3/2021by American ProCompetitive RacerAmerica12 of 16 customers found this review helpful.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.

Review by Phil WReviewed 7/26/2019by Phil WCycling EnthusiastSouthern Indiana2 of 2 customers found this review helpful.Long-lasting power and relatively durableThe 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.

Review by AlanicoReviewed 4/10/2021by AlanicoLA Back up batteryMy 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!

Review by garage0racingReviewed 6/5/2020by garage0racingKey West, FL0 of 1 customers found this review helpful.Battery tabs keep breakingNo 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.

Review by AlanSMReviewed 12/19/2019by AlanSMCycling EnthusiastFairfield County, CT1 of 1 customers found this review helpful.reliable battery with fragile plastic tabThe 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.

Review by ErcmicwilReviewed 11/28/2019by ErcmicwilSpokane, WASuper 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!

Review by DurendalReviewed 10/12/2022by DurendalCycling EnthusiastFernandina Beach, FL2 of 2 customers found this review helpful.Use superglue if you break the tab.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.

Review by twowheels2000Reviewed 6/25/2018by twowheels2000Cycling EnthusiastReno, NV2 of 2 customers found this review helpful.Just a spare batteryI'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.
