How do I get my battery rebuilt?

Step 1. Select E-Bike battery model

How do I place an order?

During the first step you search for your battery brand in the battery rebuild section. After you have clicked on the brand, all batteries that are eligible for rebuild are automatically displayed.

When you have found the battery 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 be.

Click on 'continue to the next step' if you are satisfied with the chosen capacity and check your order. After filling in your contact details, the order can be finalized by clicking on 'checkout'. You will then receive detailed shipping instructions by e-mail.

I can't find my battery, can you still rebuild it?

Even if your battery cannot be found in the product page, it is possible that we can simply recondition the battery. Because a wide variety of e-bikes are sold in the U.S, there is a chance that your specific model is not yet included. We can often tell you more about the options for your specific battery within one working day if you fill in the Intake Form.

To which address should my battery be shipped?

You will receive the detailed shipping instructions including contact details for our repair center after placing an order.

Do you also need my charger or keys?

In most cases, in order to successfully test your battery, we also need your charger. Some batteries are equipped with an ignition switch to switch the battery on / off.  In that case we also ask you to send the ignition keys, so that the battery can be tested properly.

Can I also bring my battery?

It is possible to hand in your battery at our repair center. We can then advise you and help you place an order.

Why haven't I received an email?

Normally, after placing an order, you will receive two emails: one order confirmation and one email with the shipping instructions. If you have not received confirmation after placing the order, the payment may not have been successful.

It is also possible that you made a typo when entering the e-mail address, but in most cases the e-mails ended up in your 'spam' or 'unwanted' mailbox. If no e-mails can be found in that box either, please contact us so that we can solve the problem for you.

Step 2. Battery is tested and rebuilt at our repair center

What happens after my battery arrives at the repair center?

When the package has arrived at our repair center, the battery initially undergoes a short 'pre-test'. If it turns out that the poor battery performance is due to wear of the energy cells, our repairers will proceed to overhaul.

The old energy cells are removed from the housing and replaced with grade-A energy cells from Samsung. The housing and usually also the electronics (the Battery Management System) of your old bicycle battery are reused. With a number of batteries, the electronic part of the battery is also replaced as standard. After the repair has been completed, a rigorous final test checks whether the battery can deliver the specified capacity.

Can you determine in advance whether my battery can be rebuilt?

If your battery can be found in the product page, we can usually repair your battery without any problems. Most of the batteries on the website have already been successfully rebuilt by our technicians

However, sometimes during the repair it becomes apparent that the battery is no longer functioning due to an electronic defect in the circuit board (for example due to water or fall damage). Replacing the battery will not solve the problem.

If your battery is no longer working, it is best to contact us in advance, so that we try to determine remotely whether a rebuild is still possible.

How long will I lose my battery if I send it in for rebuild?

For every order, Hi-C Battery uses a so-called 'lead time': the time required for testing, rebuilding and returning your bicycle battery. This time is variable, depending on the activity and subject to complications during the repair.

You can find the current lead time for our services in the specifications on the order page of your battery. At this moment the turnaround time is 14 working days  (this is an indication of the repair time, and is only an estimate)

Will I be notified when my battery is ready?

If the rebuild has been successfully completed, you will receive a notification by e-mail, so that you know when the battery will be returned. In addition, this email contains a tracking code for tracking the return shipment. If you have indicated that you want to pick up your battery from our repair center, we will contact you by e-mail when the battery is ready.

Step 3. Refurbished battery will be returned

Am I entitled to a warranty if I have my battery rebuilt?

You are entitled to a 12-month warranty from the original invoice date. Warranty applies only to the reconditioned cell insert and not to the electronic circuit (BMS). With some batteries we also replace the electronic part and in that case the BMS is covered by the warranty.

A defect in the cell insert will be repaired free of charge by within the warranty period.  Drop and / or water damage are not covered by the warranty.  Leaving a battery uncharged for extended periods of time will not be covered

Hi-C Battery guarantees that the nominal capacity of the chemical battery corresponds to the ordered capacity. No guarantee is given for a specific cycling distance that can be achieved with the reconditioned battery. The range depends on many factors, which makes it impossible to guarantee a specific distance.

How do I use my battery after rebuild?

After the repair has been successfully completed, you will receive instructions from us by e-mail on how to re-use the reconditioned battery. It is important that you follow these instructions to bring the battery to its maximum capacity as soon as possible. The first time you start cycling with the reconditioned battery, the battery is not yet at its maximum capacity.

What is the lifespan of my reconditioned battery?

The energy cells that are placed in the housing are completely new and, if used correctly, have an average life span of 4 to 5 years. A capacity loss of 10-15% per year is normal for lithium-ion batteries. Since the cells are subject to wear, they can lose capacity more quickly with intensive use. To extend the life of the battery, we recommend that you read our carefully.

Will the display and LED indicators on my battery still work after rebuilt?

In most cases, the LED indication on your battery and on the display will continue to work. However, especially if you are using the reconditioned battery for the first time, your display may not accurately show the current residual charge. We advise not to attach too much importance to the indication on your display, especially in the beginning, but instead to start from the number of miles that you would normally cycle

From a quality and safety point of view, we only use grade-A energy cells from Samsung. If your battery was originally equipped with other (smaller) 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 and usually this indication becomes more accurate as the battery goes through more charge cycles.

In some cases the display will not show accurate residual charge even after several charge cycles, especially when the original capacity has been significantly increased. In that case, the computer in the battery still measures the old energy values. You will then have to determine yourself how many miles can be ridden with a certain battery percentage before you lose assist.


Why rebuild?

Brands we service



A rebuild starts with inspecting your original battery.  We check over everything and note anything that is broken like a switch or a bad charging terminal.  If the battery is operational we perform a 5 min discharge and note the internal resistance.  We then charge for 5 min and check each cell voltage.  This ensures that the battery management system (BMS) is in good condition.  A rise in resistance my indicate a bad BMS and further investigation is needed. 

After this we can start the rebuild process.  We remove all the old cells and recycle them.  We then weld in brand new cells of your choice.  We use high quality USA made nickel to weld the cells together.  The process can take about 5 hours depending on  the complexity of the pack and the number of cells used.

After the battery has been rebuilt it goes through a series of tests to ensure quality.  The new battery is charged fully and each cell voltage is balanced.  Then we use our BA1800 Battery Analyzers to perform a capacity test.  Typically a newly built pack will show 95% capacity because the cells state of charge aren't perfectly balanced.  Over time the BMS will refine the balance of the cells and capacity will increase to the full 100%

After the capacity analysis the case is closed.  The final quality assurance inspection is complete and your battery is ready for many years of service.

The cells of today are a better chemistry than just 2 years ago.  We can increase the capacity and performance of your battery almost doubling your bikes range.  Our cells are fresh from the factory so you will always get the newest cells available.   Don't settle for a stock battery that has been sitting on the shelf for years, losing capacity and performance all the while.  Contact us today to discuss your battery rebuild options.
