Rebuilt Battery Service Process

For guaranteed quality and safety we only use top manufacturer brand cells, such as certified grade-A energy cells from the LG Chem Brand.  If your battery was originally equipped with other (smaller, low quality) cells, it may be that the current residual charge no longer exactly matches the value that you see on the display. With many batteries, the residual charge is displayed with 'blocks' or LEDs. Usually this indication becomes more accurate as the battery goes through more charge cycles (when new), but as your battery wears down near end-life, this gauge will become inaccurate and can lead consumers to believe the battery is still fine, when in fact it is reaching end-life.


How to place Order for Refurbish Battery

You can call us, send us an email, or browse our website and search for the correct model and listed price of your rebuild. The first step would be searching for your battery brand. When you have found the battery or brand in the overview, click on the product to proceed to the order page. Here you have the option to choose what the new capacity of your worn battery should match or be upgraded to. Give us a call if you are unsure which option is best for you.


Battery Intake Process

Next, Fill out the Battery Intake Form.(oval button on our home page, or you can scroll down to the bottom of the home page) Print out the form, and send it along with your e-bike battery, over to our Las Vegas facility. The intake form has a page that gives instructions for shipping, a label you place on your box, and our address.


EMP Builds a High Quality Battery

We will notify you when your battery arrives at our repair center. Your battery will be put through testing after the intake process. If it turns out that the poor battery performance is due to wear of the energy cells, our technicians will proceed to rebuild. If we find an issue that we can resolve without rebuilding, our team will reach out with options. EMP then rebuilds your battery quickly with high-quality, name-brand cells and provides your rebuild with a 1-year warranty. Extended warranties are also available!


EMP Returns Battery to Customer

We will then ship your e-bike battery back to you. After the repair has been completed and shipped, you will receive tracking and instructions from us via e-mail on how to use and maintain your reconditioned battery. It is important you follow these instructions to bring your battery up to its maximum capacity as soon as possible.  It is also worth mentioning that the first couple times you cycle the reconditioned battery, the battery has not yet reached it's maximum capacity. There is a break-in period that usually takes 5-10 cycles for your battery to achieve top-performance. Also, if the battery doesn't work due to malfunction of your original circuitry, and there is no other repair options, your money is fully refundable.


Stages of a Naked Battery Build

  1. Step 1

    Stage 1 of Naked Battery build process is the Individual Battery cell testing


  2. Step 2

    Is the Intershell Build where we use cell spacers to reduce heat build up.


  3. Step 3

    is the cylindrical lithium ion cells where we use the best welding process per your battery application request.


  4. Step 4

    Is where we Discharge your battery to its BMS limits to ensure it can handle the demand (100A Max limit)


  5. Step 5

    Final stage of the nake battery process where we wrap the naked battery in a flame retartad shield.
