These 19 cells are fully capacity tested by charging to a max 4.10v, then stored for 6 – 8 weeks, voltage rechecked for self-discharge and then discharging to 3.05v esh 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.
These cells are manufactured to discharge down to 3.0 Vdc from 4.20 Vdc as can be seen on their respective Data Sheets.
My 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.
Therefore these cells are capable of providing a much higher capacity reading if taken to there data sheet specs.
Please feel free to message me for any further info.
Photos form part of the description. All images in the description are of the actual items that you will receive.
We go to great lengths to clearly show our labeling that gives the individual cells performance data and forms part of the items description.
What you see is what you get, check our feedback score. Our combined cell count over our range of products goes well beyond 60k refurbished cells.
We will also combine postage with other items so as to reduce shipping cost. Local pickup is also available.
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.
The health of a battery is based on three fundamental attributes:
Capacity, the ability to store energy. Capacity is the leading health indicator of a battery
Internal resistance, the ability to deliver current
Self-discharge, indicator of the mechanical integrity
When making these measurements you must consider type and accuracy of equipment used, as well as ambient and battery temperature.
