Warranty & Refund Policy

Limited Warranty

Maxx Volts offers charger systems designed for specific vehicle year, make, and model applications.

EL-1 Series charger systems are covered by a 6-month limited warranty against defects in materials or workmanship and against power-supply failure under normal intended use.

Premium Line charger systems are covered by a 2-year limited parts-and-labor warranty against defects in materials or workmanship under normal intended use.

This limited warranty does not cover:

• misuse or abuse
• improper installation or improper voltage input
• unauthorized modification or alteration
• normal wear or cosmetic damage
• damage caused by improper packaging during return shipment
• damage caused by use contrary to Maxx Volts instructions

If a covered warranty issue occurs within the first 30 days after delivery, contact Maxx Volts by email with a description of the issue. If the issue is covered under this limited warranty and cannot be resolved through troubleshooting, Maxx Volts will issue an RMA and provide a prepaid return shipping label. Maxx Volts will pay the shipping cost to return the item to our service center and the shipping cost to send the repaired item back to you.

If a covered warranty issue occurs more than 30 days after delivery but within the applicable warranty period, contact Maxx Volts by email with a description of the issue. If the issue is covered under this limited warranty and cannot be resolved through troubleshooting, Maxx Volts will issue an RMA. In that case, the customer is responsible for shipping costs to Maxx Volts and for return shipping back to the customer, unless otherwise required by law.

Items returned for warranty service must be properly packaged. Use the original box and packing materials whenever possible. Maxx Volts may deny warranty coverage for shipping damage caused by inadequate packaging.

Service / RMA Procedure

A valid RMA number is required for all approved warranty-service returns and all approved out-of-warranty repair returns. Packages received without a valid RMA may be refused.

Before Maxx Volts will issue an RMA for a claimed defect, the buyer must participate in reasonable troubleshooting requested by Maxx Volts so that we can determine whether the reported issue is caused by installation error, operating conditions, misuse, shipping damage, or an actual defect in materials or workmanship.

Reasonably requested troubleshooting may include photographs, video of the unit’s operation, video or photos of the installation and connections, serial-number information, voltage readings, and a written description of the issue and the steps already taken.

Providing this information is a required part of the warranty-evaluation and RMA process. If the buyer does not provide the requested troubleshooting information, Maxx Volts cannot determine whether the claim qualifies for warranty service, and no RMA will be issued unless and until the requested information is provided.

If a product is outside the warranty period and requires repair, contact Maxx Volts by email with a description of the issue. If troubleshooting does not resolve the issue, Maxx Volts will issue an RMA. After receipt and inspection, Maxx Volts will provide a repair estimate, including applicable shipping charges, before any non-warranty repair work is performed.

If inspection and testing show that a product is operating properly, or that the reported issue results from improper installation, improper voltage input, misuse, unauthorized modification, or another non-warranty cause, the claim will not qualify as a covered warranty claim. In that event, the buyer may be responsible for applicable shipping, diagnostic, and repair charges unless otherwise required by law.

Custom-Built Orders / No Cancellations / No Refunds

Maxx Volts charging systems, dischargers, wiring harnesses, and related electronic tools are built, configured, allocated, serialized, and/or customized to customer order. These are specially manufactured goods and are not stocked for general retail resale.

Because production, customization, serial-number assignment, engraving, and order-specific allocation begin promptly after an order is placed, orders for these products may not be cancelled once processing or production begins.

There are no customer-convenience returns, no change-of-mind returns, and no refunds on charging systems, dischargers, wiring harnesses, or electronic tools. All such sales are final, except to the extent a remedy is expressly available under Maxx Volts’ written limited warranty or otherwise required by law.

Refusal of delivery, failure to accept delivery, or return-to-sender status does not cancel the order and does not create a right to a refund. If a customer refuses delivery of a custom-built order, Maxx Volts reserves all rights and remedies available under applicable law.

No package may be returned to Maxx Volts without a valid RMA.

Do not return any package without a valid RMA number. Unauthorized returns may be refused.

Limited 90-Day Used/Reconditioned Hybrid Battery Module Warranty

Coverage period. Maxx Volts warrants the individual used/reconditioned hybrid battery module identified on the applicable order against a verified defect in that module for 90 days from the original delivery date.

Module only. This warranty does not warrant the complete battery pack, vehicle, installation labor, diagnosis, pack balancing, state-of-charge matching, battery control system, voltage-sensing system, wiring, bus bars, terminals, or another component not supplied as part of the warranted module.

Warranty remedy

If a covered defect is verified, Maxx Volts will exchange the module for a tested used/reconditioned module from the same purchased capacity tier. If a suitable matching module is not available within a reasonable time, Maxx Volts may instead refund the original module purchase price or offer another remedy accepted by the customer. Removal, installation, diagnosis, balancing, towing, downtime, and other vehicle expenses are not included.

The customer is responsible for properly packaging and shipping the claimed module to Maxx Volts. If the claim is approved, Maxx Volts will pay standard shipping for the replacement module to the original U.S. delivery address, unless the original order stated a different shipping allocation.

How to open a claim

Contact Maxx Volts within 90 days after original delivery. Provide the order number, purchaser contact information, module serial or identifying mark, vehicle year/make/model, and a description of the problem. Also provide any available relevant trouble codes, photographs, voltage data, or other diagnostic information.

Diagnostic data helps evaluate a claim but is not a substitute for identifying the module sold. A customer who does not have specialized diagnostic equipment may return the identified module for Maxx Volts testing. Do not ship a module until Maxx Volts issues an RMA and return instructions.

How a covered defect is established

Maxx Volts will verify the returned module identity and evaluate it using a documented procedure materially equivalent to the procedure used to qualify modules for sale. A covered defect is established when testing shows one or more of the following:

• Discharge capacity below the lower limit of the purchased tier: below 4.0 Ah for a 4.0–5.0 Ah module, or below 5.0 Ah for a 5.0–6.0 Ah module, when tested by the applicable Maxx Volts procedure.
• Abnormal voltage collapse under the applicable controlled load test attributable to the module.
• Abnormal self-discharge under the applicable controlled test attributable to the module.
• An internal open circuit, short circuit, electrolyte leak, or other physical or electrical failure originating within the module and not caused by an excluded condition.

Resting voltage alone does not establish capacity, self-discharge, or load performance. A warning light, diagnostic code, weak block, continued pack problem, or difference between modules does not by itself establish that the identified Maxx Volts module is defective. Maxx Volts will provide the approval or denial and the principal test result or other reason supporting the decision.

Conditions not covered

This warranty does not cover a problem or damage caused by incorrect installation; reverse polarity; short circuit; loose or incorrectly torqued connections; damaged or corroded bus bars or terminals; improper charging, discharging, matching, or balancing; a fault in another module or vehicle component; modification; puncture; crushing; impact; fire; flooding; collision; excessive external heat; inadequate return packaging; return-shipping damage; or use outside the intended compatible application.

Maxx Volts may rely on an exclusion only when inspection, test results, photographs, or other available evidence reasonably supports that the excluded condition caused or materially contributed to the claimed failure. Installation by the customer or an independent repairer does not by itself void this warranty, and ownership or use of Maxx Volts-branded equipment is not a condition of warranty eligibility.

Serial verification and modules that pass testing

The returned serial or identifying mark must correspond to the module supplied under the claimed order. A substituted module is not covered under that order. If the identified module passes the applicable capacity, load-performance, and self-discharge tests and no covered internal defect is found, the claim will be denied and the module will be made available for return. The customer is responsible for return shipping of a non-defective module.

State-law notice. This limited warranty gives the customer specific legal rights, and the customer may also have other rights that vary from state to state. Nothing in this warranty excludes rights that cannot lawfully be excluded or limited.
