Kúpil som takú detskú srandu, bola tam 18650 batéria že 1900mAh
Keď som ju nabíjal vošlo tam presne 100
Toľko k mega dobrej číne, ale platí není Čína ako Čína

Kolko sa tu nariekalo a pytalo na riesenia?

Sumasumarum… baterka za 15€ nie je az taky dobry deal, kedze tam je velka variabilita v konzistetnosti kvality pocas zivotnosti. Tj. Ked ti to klakne pocas 100km vyjazdu. Dik ide, dik nejde. Googli a dozvies sa viac.

So sram bateriou take ani gugl nezna.

Gúgl ? tak si kupuj ten sram, na niektorych musia zarobit no. Bolo aj tu par ludi co im to iste robili origo baterky. Ale tak ver si comu chces.

Tebe honoria nieco data? Ci iba “ak to povie FB?”

Teraz som dal kamosovi promt… citaj pozorne.

Niektore baterie ostanu na cervenom v nabijacke, ale uz je trik ako ju ozivit. Ak umrie nabijacka… mas dalsiu.

By chatGPT:

There’s no official/statistical “failure rate” published by SRAM for original AXS batteries. However, based on user experience and community data:



✅ Original SRAM AXS Batteries
• Generally reliable, lasting for years if used and charged properly.
• Common issues arise from dirty contacts or spring-loaded pin corrosion, not inherent battery failures  .
• Some users report one-off charger errors after ~1–2 years, but these are usually recoverable or coverable by warranty ().
• As for CR2032 coin cells in shifters, they typically last ~2 years under normal use .

? From user reports:

“One bike gets used daily… have 9 batteries in rotation… original batteries are still in rotation.” 



⚠️ Third‑Party / Chinese Clone Batteries (e.g., AliExpress, Amazon knock‑offs)
• Risks include poor sealing, short-circuits, overheating, and even fire .
• Mixed reports on performance: Some users say clones last a season or more, but longevity is uncertain .
• Communities note that clones may have shorter lifespans and less safety, making them a gamble—any savings (~€10–20) may not justify the risks ().

? From user quotes:

“I never used a proper SRAM battery… nice being able to wait till the battery is dead… I think I used both once on a 5000 mile season and never sweated charging.” 
“Some of Chinese knock offs can actually be quite dangerous… risk of electrocution, short circuiting, lithium batteries combusting.” 



? Estimated Failure & Reliability Overview

Battery Type Typical Lifespan Failure Mode Failure Rate*
Original SRAM 12–36+ months Charger errors, contact issues Very low (<5%)
Coin-cell (CR2032) ~2 years Normal depletion, some early drains Low, brand-dependent
Third-party clone 6–24 months? Safety hazards, poor sealing, poor longevity Moderate to high (speculative)

*Failure rates are based on anecdotal and community-driven reports, not formal studies.



? Recommendations for Reliability & Safety
• Stick with original SRAM batteries for guaranteed performance and warranty.
• Maintain contact cleanliness: regularly clean/polish spring pins to avoid false failures    .
• Use the official charger or a certified USB‑C multi‑port option for consistent charging .
• If considering clones, treat them as emergency backups only, accept shorter lifespan, and never trust them fully—especially on long rides or remote trips.



? Summary
• Original SRAM batteries are robust; failure rates are very low when maintained well.
• Clone batteries offer cost savings but at the price of potential safety hazards and inconsistent reliability.
• If you rely on flawless shifting performance and longevity, go with the genuine battery and follow proper maintenance.
• If you’re okay with a budget backup and accept the risks, a clone might work short-term—but never depend on it as your primary.

Let me know if you’d like help sourcing reputable originals or choosing a multi-port USB‑C charger!

Ja som aj chcel kúpiť z Ali ale tri objednávky od troch rôznych predajcov mi vždy stornovali po tom ako sa to zaseklo niekde v triediacom centre.
Vždy s rovnakou správou, že v zásielke sú nepovolené produkty - batérie. Máte link na tie čo vám prišli?

Jaaaj … teraz som zistil, ze potrebujem spravit micro adjustment na transmission a uz som na 14/14 pri sram kazete. Kamos mal tento problem a nejak som to spravil, ale neviem ako presne ??‍♂️
Nemate na to trik?

Edit: teraz to mam na 12/14, vyzera ze to bude asi OK.

Edit2: da sa to oklamat. V apke zacnes klikat na micro adjustment, ktorym smerom to chces posunut. Rychlo naklikas 3-4 posunutia (a kym sa salter posunie) rychlo odpojis baterku.

Pripojis baterku a poloha bude posunuta.
Skusim natocit aj video a dam ho na YT.


Nerobil si náhodou to video?

Nie. Potrebujem na to 3 ruky a zatial ich nemam. Podarilo sa mi (asi) posunut salter o 2-3 kliky (0.6mm)

Strohy postup co som pisal do Sramu


- In AXS app opening drivetrain setting - micro adjustment setting
- during fast tapping (down in my case) fast disconnect and connect battery maybe 2-3 times; basically to not allow shift.
- derailleur has positioning memory, needed to try several times

Ak potrebujes s tym pomoct, tak si mozeme zavolat.

Ahojte. Neviete mi poradit alebo poslat video navod ako na ovládači axs pod aj rocker prehodim tlacitka aby vykonavali ukon opačne- reverzne? Ked som sparoval novu sedlovku reverb k dalsiemu pod ovladacu tak mi na prehadzovacke zmenilo chod radenie na reverzne. Skusal som to v app nastavit ale nechce ma to pustit do controler setting. Tak isto by som si zmenil aj chod sedlovky na ovladaci len mi to tiez nejde. Jeden ovladac je rocker druhy je Pod d1. Vdaka
