Warranty & Support
Contact Lithos Battery first if you experience a problem. Bill will help review the issue, and eligible warranty cases will be handled through the manufacturer’s after-sales process.
Register your battery
Register directly with DigiMarker using the manufacturer’s registration form. Have your receipt, battery model, serial number and purchase details ready. Information you submit there goes directly to the manufacturer.

For selection, installation or an existing order, contact Bill at bill@lithosbattery.org or 800-391-5988. Message Bill with an installation question. Your battery purchase includes free video installation guidance, by appointment. Bill confirms the time after you submit a request.

Returns, cancellations & refunds
General returns
Request a general return within 14 days of purchase. The battery must be unused, in its original condition and original packaging. Contact Bill first for authorization and the correct return address. Do not send a battery to an address on this website without return instructions.
This is not an unconditional free-return offer. Return authorization and the applicable shipping or handling charges must be confirmed before you send the product. General returns carry outbound and return shipping charges; confirm the arrangements with Bill before returning a battery.
Shipping damage or an item that differs from its description
Contact Bill within 14 days of delivery. Keep the packaging and take photos of the battery, packaging and damage or discrepancy. These claims are reviewed separately from a change-of-mind return.
Battery quality or performance problems
Report a quality or performance issue within 14 days of delivery. Keep your purchase proof and installation information. Manufacturer diagnostics and verification of correct installation are required to confirm a defect. Faults reported later are assessed under the applicable limited warranty.
Cancel an order
Contact Bill as soon as possible and include your order reference. Bill will check whether processing or shipping has started and explain the available cancellation or return steps. A cancellation request does not itself cancel an order.
Refunds
Approved refunds go back to the original payment method. They typically appear within 2–7 business days after processing, depending on the payment provider. Contact Bill with your order reference if you need help checking a refund.
