Overview & Technology

SRAM eTap / AXS Battery (Part #00.3018.102.000) is the official replacement power pack for SRAM wireless road derailleurs. This compact, rechargeable lithium-ion battery is engineered to the same tolerances as OEM units and uses SRAM's snap-fit interface for tool-free installation and secure retention under real-world riding loads. Built for road use and optimized for SRAM's eTap and AXS ecosystems, the battery features robust contact points and sealed construction to resist moisture and debris during wet rides. Forest Bikes lists this product under SKU 660232 — an easy way to match the correct battery to your eTap or AXS eTAP derailleur.

Fit, Compatibility & Specifications

This battery is compatible with SRAM eTAP and AXS eTAP derailleur families — including RED, Force and Rival AXS electronic derailleurs that use the same removable battery standard. Confirm compatibility with your derailleur model before ordering; the SRAM Model ID for this unit is EP-EAC-BAT-A1 and the manufacturer's part number is 00.3018.102.000.

Avoid third-party chargers unless explicitly stated compatible.

Who This Battery Is For

Ideal for road cyclists running SRAM wireless shifting who need a direct OEM replacement battery. If you've noticed diminishing battery life, frequent low-battery warnings in the AXS app, or a dead derailleur after storage, this unit restores full wireless shifting functionality quickly and simply. Also essential for riders who prefer carrying a spare on long rides or multi-day events — a backup OEM battery eliminates downtime and the need for immediate service while on the road.

Frequently Asked Questions

How do I know this battery is compatible with my derailleur?

This battery is a direct replacement for SRAM eTAP and AXS eTAP derailleurs. Check your derailleur model (RED, Force, Rival AXS families) and the SRAM Model ID EP-EAC-BAT-A1 or manufacturer's part number 00.3018.102.000 to confirm compatibility.

How long does one charge last?

Actual run time depends on conditions and usage patterns; many riders see multiple weeks of regular riding on a single charge. Heavy shifting, extreme temperatures and prolonged electronic accessory use will reduce runtime, so carry a spare for long or remote rides.

How do I charge the battery?

Charge using SRAM-compatible chargers or official AXS charging accessories. Remove the battery from the derailleur, attach it to the appropriate charger or cradle, and follow the charger's indicator lights. Avoid using unverified third-party chargers unless explicitly declared compatible.

Can I replace the battery myself?

Yes — the battery is designed for tool-free, snap-in replacement. Pull the old pack out of the derailleur, slide the new pack into place until it clicks, and verify shifting operation. Always power-cycle and check battery level in the AXS app if available.

What maintenance or precautions should I take?

Keep contact surfaces clean and dry, avoid prolonged exposure to high heat or direct flames, and do not disassemble the pack. Recycle or dispose of the battery according to local regulations and SRAM’s guidelines when it reaches end of life.

Is this an OEM SRAM part?

Yes — this is an OEM SRAM replacement battery (SRAM Model ID EP-EAC-BAT-A1, MPN 00.3018.102.000) sold under SKU 660232 at Forest Bikes.

Buying Guide

When replacing an electronic derailleur battery, choose OEM parts like this SRAM EP-EAC-BAT-A1 for guaranteed fit, contact alignment and expected performance. Consider keeping one spare battery if you ride long distances, commute, or race — swapping a charged pack takes seconds and prevents a dead derailleur from ending your ride. Check that you have a compatible charger (official SRAM/AXS chargers are recommended), inspect contact surfaces before installation, and follow proper disposal/recycling procedures for used lithium-ion packs. If you ride in cold climates, remember battery runtime can drop in low temperatures — warm the pack before installation for best performance.
