These used Sanyo 18650 lithium ion batteries were pulled from laptops and other devices. These have a rated capacity of 3200-3300mAh and are capable of a 10 amp continuous discharge. All of these cells have actual capacity above 75% of the manufacturer's rating*.
Typical part numbers include:
NOTE: Sanyo part numbers are incredibly difficult to read, so we typically go off of wrap and ring colors. Even these might vary in appearance. We do our best to match cells to their true capacities, but cannot guarantee that we will get it right 100% of the time.
These are used cells. They were charged to 4.2v, left to sit for at least one week, then discharge tested at 500mA. We may wrap cells in new heat shrink if the original wrapping was significantly damaged. These may still be delivered with adhesive or tape still attached, or damaged heat shrink.
You can find data sheets with full specifications right here.
These are used cells. Higherwire safely removes them from consumer electronics battery packs and analyzes them using the same process and equipment as many lithium-ion battery OEMs. That includes a full charge at a rate at or below the manufacturer's specification, internal resistance using both DC and AC analyzers, and full monitored discharge testing to determine capacity. They are then graded according to these and other key characteristics as compared to OEM data sheets.
We may wrap cells in new heat shrink if the original wrapping was significantly damaged. We inspect every cell for corrosion, pitting or damage and recycle any that are suspect. Cells may be delivered with adhesive or tape still attached, or damaged heat shrink. Check out or selection of pre-cut heat shrink, adhesive insulator rings and other accessories to help you finish your build.
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 Higherwire 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 Higherwire are used and have no warranty, either from Higherwire 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. Contactsales@higherwire.comimmediately 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 Higherwire are charged to 40% SOC (~3.4v) 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. Contactsales@higherwire.comwith any questions, including technical.
Unless otherwise stated, batteries sold by Higherwire are shipped as UN3480 per DOT and IATA regulations. We ship using ground shipping to minimize risk of damage to persons or property.
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 email@example.com 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.
