These LiFePO4 cells were removed from deep cycle and marine applications. These were rated at 3.5 amp-hours and 14 mΩ (AC 1kHz) when new. They've undergone full capacity testing and are batched according to their percentage of original capacity. We've used these in low-drain applications with great success.

Larger orders will include plastic holder brackets similar to that shown in the photo.

Lithium Battery Safety

  • Misusing or mishandling a lithium-ion battery may cause fire or explosion, which can result in personal INJURY or DEATH and property damage. You MUST read the safety warnings and resources before purchasing, using, and/or handling batteries. Even if properly handled, lithium-ion batteries may still catch fire or explode. The buyer acknowledges these risks and absolves Higher Wire Inc. of any responsibility for any damage these cells may cause.
  • Unless otherwise stated, batteries sold by Higher Wire are unprotected and not recommended by us or their original manufacturers for use unless equipped with a protection circuit board (PCB), battery management system (BMS), and/or similar device.
  • Lithium batteries must be properly disposed of – NOT in a fire or in the trash. Laws vary at the city, state and national level, and it is the buyer’s responsibility to ensure they are recycling lithium batteries properly. Many local governments and retail stores offer free recycling, and you should review our How to Recycle Lithium Batteries page.
  • Unless otherwise stated, batteries sold by Higher Wire are used and have no warranty, either from Higher Wire or the original manufacturer. Although we visually inspect and analyze/grade all batteries prior to sale, it is the buyer’s responsibility to inspect all batteries for physical damage, corrosion, and voltage upon receipt. Contact us immediately if there are any issues with an order, and do not use any battery that is damaged or below 3.0 volts upon receipt.
  • Unless otherwise stated, batteries sold by Higher Wire are charged to 40% SOC per IATA and DOT regulations. Charge battery fully to 4.2V before first use.
  • Never attempt to mix and match brands, including models as well as old and new, used, and unused lithium-ion batteries. It is the buyer’s responsibility to ensure a battery is compatible with the intended application. Contact us with any questions, including technical.
  • Unless otherwise stated, batteries sold by Higher Wire are shipped as UN3480 per DOT and IATA regulations. We ship using ground shipping to minimize risk of damage to persons or property.
  • Go to our Lithium Battery Safety page for full 18650 lithium battery safety precautions.

We ship the majority of our orders by the next business day. Lithium batteries may take up to two business days to process to accommodate inspection and logging into our system.

Our shipping rates are based on the weight of all ordered products plus estimated weight of packaging. We make every effort to forecast an accurate shipping cost, but cannot be 100% certain in all cases. Please contact us at with any questions prior to purchase.

We pack and label all lithium battery shipments in accordance with Federal Regulation 49CFR173.185, as well as USPS Publication 52 Hazard Class 9 or UPS/Fedex guidelines. Unless otherwise stated, lithium batteries are not eligible for free shipping.

We try to pack all items in an order in a single box, however we may on occasion need to ship items separately. Special shipping does not apply to lithium ion batteries, and orders that include batteries may not qualify for free or expedited shipping.
