Out of stock
THE STAINING ON THE TOP OF THE CELLS IS DUE TO THE OVERUSE OF A ELECTRICALY CONDUCTIVE GELL USED DURING THE LIFE OF THE BACKUP UNIT AND AS YOU CAN SEE FROM THE ACTUAL IMAGES THAT THE TEST RESULTS ARE OUTSTANDING WITH HIGH CAPACITY AND GENERALLY LOW RESISTANCE. IF YOU NEED MORE INFO PLEASE CONTACT US ASAP FOR A FULL EXPLANATION.
These cells are Batch tested for capacity by charging to a max 4.15v, then stored for 6 – 8 weeks, voltage rechecked for self-discharge and then discharging to 3.05v which allows the cell to return its internal voltage to around 3.45v for shipping via Australia Post or Sendel Couriers. Any cell showing a resistance in excess of 100 mΩ are disposed of. We provide the resulting available mAh as a guide for the balancing of your multi cell battery builds.
Batch Test results report is included
N.B – No Spotwelding or Soldering on either end of the cells.

The health of a battery is based on three fundamental attributes:
When making these measurements you must consider type and accuracy of equipment used, as well as ambient and battery temperature.
All cells have been batch tested on our Liito Kola Lii 500 testing stations.
These cells are manufactured to discharge down to 3.0 Vdc from 4.20 Vdc as can be seen on their respective Data Sheets.
Our standard capacity discharge test, discharges to approx 3.05 Vdc down from 4.15-4.20Vdc depending on the cells impedance and has produced the labeled test results in the photos.
What you see is what you get, check our feedback score. Our combined cell count over our range of products goes well beyond 70k refurbished cells.
Local pickup is also available. We will also combine postage with other items so as to reduce shipping costs.
Manufacturers Data Sheets provide an excellent insight into the cells design capabilities and parameters and Google is a great tool to find them. Just look for the cell data on the cell wrapping and search accordingly.Due to the nature of our Lithium products we offer no guarantees as to their use by the end users skill set and do not warrant there end use in any way.
There are 69 PANASONIC NCR18650 cells.
Please check for best shipping price and your prefered method in the checkout then, “check the shipping button accordingly” when ordering, as shipping is dependant on delivery address.
We have loads of unlisted stock so if you need cells you dont see just ask!
