How to harvest modem packs:

*Note: The video below demonstrates how to harvest cells from new modem packs, but keep in mind that the packs from this lot may not be new.

Note that these are reclaimed packs, so the actual cell voltage you receive may be lower than the label shows. We make no guarantees that all cells will be usable. These items are sold for DIY and Second Life purposes. Sold as-is. No refunds. Buyer is responsible for proper cell recycling/disposal.


Listings that are “untested” as sold as-is and cannot be returned, exchanged or refunded. These items are sold for DIY and Second Life purposes. Even when sold as “new”, “NOS”, or “like-new”, they may be in less than perfect condition.

NEW YORK residents:
On 3/2/2023 New York passed a law banning the sale of lithium-ion batteries for mobility devices that are not certified to UL 2271, and the assembly and reconditioning with cells removed from used batteries for commercial sale within the state of New York (more details here). New York residents, you are solely responsible for researching, understanding and complying with all pertinent regulatory rules, laws, statutes, and NY safety standards.

Safety is important to us, we don't want people to get hurt or property to get damaged, especially when working with DIY and/or second-life lithium-ion batteries. All batteries everywhere are inherently dangerous, so we urge all who work with DIY and/or second-life lithium-ion batteries to take safety seriously so as to avoid causing any harm to self, others or property.
