BatteryPacks.com does not provide any guarantee of compatibility, suitability, or fitness for any particular purpose (e.g. a particular electronic device or particular electronic application). The purchaser or user is solely responsible for determining whether a particular battery is suitable/compatible for use in a particular electronic device or for a particular electronic application. Lithium batteries sold by BatteryPacks.com are for the intended use of system integrations with proper protection circuitry or battery packs with a BMS (battery management system) or PCB (circuit board/module).

BatteryPacks.com does not provide a warranty for any item sold. Any warranty applicable is provided by the manufacturer of the product purchased. All products sold by BatteryPacks.com are NEW merchandise unless specifically noted to the contrary in the item description.

BatteryPacks.com will facilitate warranty exchanges within 30 days of delivery on behalf of customers for products which have a stated Manufacturer's Warranty. Any claim for warranty, if offered by the manufacturer, outside of this time frame shall be pursued with the manufacturer. Products without a stated Manufacturer's Warranty are not eligible for warranty replacement from BatteryPacks.com. Offer of warranty exchange is NULL and VOID if the product is disassembled, modified, repaired, abused, misused, physically damaged, or otherwise not in the original state when sold except for having reasonable wear and tear.

The customer is responsible to ship the eligible item and once received BatteryPacks.com will ship a replacement at its expense in exchange. All the original packaging, materials, etc must be included as these items are considered part of the product. Please note manufacturer warranties typically do not cover any damages due to accidents, misuse or negligence and these instances will not be covered under BatteryPacks.com's warranty exchange policy. Product warranties are limited to the value of goods sold and do not cover any associated damages. BatteryPacks.com makes no further warranties unless specified in writing between the parties on this document.

Defective Cells (DOA/Dead on Arrival)

If you received a battery which is DOA (completely dead, 0 voltage, will not accept a charge whatsoever), please contact us within 7 days of delivery for issuance of an RMA. A cell which is DOA may be exchanged for a new replacement of the same brand/model under the following conditions:

    • Batch/Serial numbers must match those which originated from our facilities
    • Cell(s) must be new/unused, in the original condition as shipped/received, without any signs of use
    • All original packaging must be included

Once the item is received, inspected, and tested to be DOA, a new replacement of the same brand/model will be provided. Return shipping costs of DOA claims are at the expense of the customer; however, the shipping costs of the replacement(s) are at the expense of BatteryPacks.com. Once the 7 day window has passed our DOA policy shall expire and an RMA will not be offered. Our DOA policy does not apply to used batteries.

Returns - RMA (Return Authorization)


If an order is refused, marked return to sender, or deemed undeliverable by the carrier due to an incorrect address or otherwise, the customer will receive a refund for the purchase price of the products less: 

    • 10% restocking fee,
    • Original amount of Outbound Shipping*, and
    • Any applicable return shipping fees assessed to the parcel by the carrier.

* Orders with "free shipping" will have the actual outbound cost deducted as well. 

The applicable refund will be processed within 5 to 7 business days after the package has been received at our facility.

RMA (Return Authorization)

You must obtain a Return Merchandise Authorization ("RMA") number within the applicable period. BatteryPacks.com will not accept warranty exchange or DOA claims without prior authorization and an RMA number. Once issued, RMA numbers are valid for 15 days. BatteryPacks.com must receive the returned products within this time frame. RMA numbers will not be extended or reissued. The customer should prominently display the RMA number(s) on the shipping label of boxes containing the returned product.

Please note the issuance of an RMA number itself does not guarantee a warranty exchange, replacement, or otherwise if the claim is found to not be within the coverage of our policies.

The customer is responsible for costs related to the logistics of returning warranty exchange and DOA claimed items. We recommend using a service with tracking and/or insurance as we are not responsible for lost or damaged returns.
