Epoch Batteries Warranty Repair Process

Step 1: Initiate Your Warranty Repair Request

Begin the warranty repair process by logging into our Repair Portal.

Please complete the form with the required information, including the battery serial number and a brief description of the issue. Be sure to attach any relevant photos to support your claim.

Once your request is submitted, it will be reviewed by our team. If approved, you will receive a prepaid UPS shipping label to send the battery to us for inspection and repair.

Please note: While the initial shipping label is provided, you are responsible for return shipping costs following diagnosis and repair.

If the issue is determined to be the result of factors outside of a manufacturing defect—such as over-discharge, improper storage, misuse, or other forms of damage—the customer will be responsible for all associated costs. This includes parts, labor, and return shipping fees.

Step 2: Prepare and Ship the Battery

If the original packaging is no longer available, it is the customer's responsibility to ensure the battery is securely and safely packaged for return shipment. Packaging must comply with all applicable shipping regulations for hazardous materials, including the use of a UN-approved lithium-ion battery shipping box.

Epoch Batteries is not responsible for any damage incurred during transit due to improper packaging. We strongly recommend retaining the original packaging or consulting with a qualified shipping provider to ensure your return is packaged safely and in full compliance with shipping standards.

Once your battery is properly packaged, use the provided prepaid UPS shipping label to return the product to us.

Step 3: Repair Process

Upon receipt of the battery, our technicians will conduct a thorough evaluation and carry out any necessary repairs in accordance with the terms of the warranty.

You will be kept informed throughout the process. Typical repair turnaround times range from 3 to 10 business days, depending on the nature of the issue.

If the repair is determined to fall outside the scope of a manufacturing defect—such as damage caused by misuse, improper storage, or over-discharge—the customer will be notified accordingly. In such cases, the customer will be responsible for all costs associated with the repair, including parts, labor, and return shipping. An itemized invoice will be provided prior to any work being completed.

Step 4: Return of the Repaired Battery

Once repairs are completed, your battery will be shipped back to you. A tracking number will be provided via email upon dispatch so you can monitor the delivery status.

Please Note: While Epoch Batteries provides a prepaid UPS label for the initial shipment to our facility, return shipping costs will be the responsibility of the customer if the repair is determined to be outside the scope of a manufacturing defect. These charges will be included in the final invoice.

Epoch Chargers – 2-Year Limited Warranty

Epoch Batteries warrants that all chargers sold under the Epoch brand, whether directly or through authorized distributors and dealers, are free from defects in materials and workmanship for a period of two (2) years from the original date of purchase, as verified by the buyer’s sales receipt (“Warranty Period”).

If a charger is found to be defective during the Warranty Period, it will be eligible for replacement at no cost to the customer, provided the issue is determined to be the result of a manufacturing defect and not due to misuse, improper installation, physical damage, unauthorized modifications, or exposure to unsuitable environmental conditions.

This warranty is non-transferable and applies only to the original purchaser.

Epoch Accessories – 1-Year Limited Warranty

EDG Sales International LLC (the manufacturer, hereinafter referred to as “Epoch Batteries”) warrants that each accessory component—including but not limited to chargers, fuel gauges, voltage reducers, and other accessories—sold by Epoch Batteries or its authorized distributors and dealers will be free from defects in materials and workmanship for a period of one (1) year from the date of purchase, as indicated on the buyer’s sales receipt (“Warranty Period”).
