Faraday Battery Rebuild Service – Bring Your Faraday E-Bike Back to Life

Faraday Electric Bikes were known for their timeless styling, lightweight steel frames, and hidden battery design. Models like the Faraday Porteur and Faraday Cortland quickly became favorites among urban commuters who wanted an e-bike that looked like a traditional bicycle.

Unfortunately, when Faraday ceased operations, owners were left with a difficult problem—replacement batteries became nearly impossible to find. Today, many Faraday owners have perfectly functional bicycles sitting in garages simply because the battery no longer holds a charge.

The good news is that in many cases, the original battery can be professionally rebuilt.

Why Faraday Batteries Are So Difficult to Replace

Unlike many modern e-bike manufacturers that use standardized battery cases, Faraday designed its batteries specifically for its own bikes.

Because the company is no longer manufacturing replacement packs, riders often discover that:

OEM batteries are no longer available
Used batteries have heavily degraded cells
Remaining replacement parts are extremely expensive
Dealers have little or no access to replacement inventory

This has become one of the biggest discussion topics among Faraday owners, with many riders searching for alternatives instead of retiring an otherwise excellent bicycle.

A Battery Rebuild Is Often the Best Solution

Instead of searching for a discontinued replacement battery, EMP rebuilds your existing Faraday battery housing using new premium lithium-ion cells.

During a rebuild, our technicians:

Completely disassemble your original battery
Remove all aging lithium-ion cells
Install a matched set of premium replacement cells
Inspect wiring, nickel strips, insulation, and safety components
Evaluate the Battery Management System (BMS)
Balance and test the completed battery before shipment

Whenever possible, we preserve your factory housing so your battery continues to fit exactly as it did from the factory.

Can Capacity Be Upgraded?

Depending on the internal space available inside your specific Faraday battery, we may also be able to increase capacity using newer high-energy lithium-ion cells.

Potential benefits include:

Longer riding range
Improved voltage stability
Better overall performance
Longer service life than worn original cells

Every battery is different, so upgrade options are determined during inspection.

What If the BMS Has Failed?

Some Faraday batteries use proprietary electronics that can complicate repairs.

After receiving your battery we perform a complete diagnostic to determine:

Cell condition
Battery Management System (BMS) operation
Charging performance
Overall rebuild feasibility

If additional repairs are required, we'll contact you before proceeding.

Our goal is to save your original battery whenever it is practical to do so.

Why Riders Choose to Rebuild

A professional rebuild offers several advantages:

Keep your original battery case
Maintain the factory appearance of your bike
Avoid searching for discontinued batteries
Reduce electronic waste
Restore confidence in your daily rides

For many Faraday owners, rebuilding is significantly more practical than trying to locate an aging replacement battery that may already have degraded cells.

We can evaluate batteries from many Faraday bicycles, including:

Faraday Porteur
Faraday Cortland
Kickstarter Edition models

Restore Your Faraday Instead of Replacing It

Faraday built beautiful bicycles that deserve to stay on the road. Just because replacement batteries have become difficult to find doesn't mean your bike has reached the end of its life.

EMP specializes in rebuilding discontinued and hard-to-find e-bike batteries, helping riders extend the life of their original equipment while avoiding the cost of replacing an entire bicycle.

If your Faraday battery has lost range, won't charge, or no longer powers your bike, we're here to help.
