Second-life Market
A battery is a sealed unit, in the majority of cases its physical condition doesn’t give an indication of the capacity remaining in the battery or its future potential.

Energy storage manufacturers require batteries that suit their particular needs and above all are reliable. Faults with batteries can affect energy supplies and impact revenue.
Time consuming
Battery testing takes time as each battery pack is tested separately and needs to be power cycled.
Expensive
Battery testing costs money and if the battery is found to be of poor quality then another battery will need to be tested.
Technical
Battery testing is undertaken by specialist personnel using advanced technical equipment that measure chemical changes in the battery.
What are the benefits of supplying EV batteries to the second life market?
Cost
Second-life batteries are cheaper than comparable new batteries which benefits second-life producers and provides additional revenue to vehicle manufacturers.
Weight matters less
The second life market generally provides batteries for fixed locations (rather than travelling in a vehicle) and as such the weight and size of a battery is less important —meaning lower grade batteries can be combined to match the output you require.

Battery passport is the equivalent of a vehicle’s odometer, providing the buyer with a quick and simple way to see the life the battery has had, helping to determine the price and the future expectations of that battery.
In addition to a clear and simple rating, Battery Passport offers a rich set of data to help second-life purchases find the right batteries that meet their requirements and this data is available while the battery is still in use or in storage.
A battery passport contains the following information:
The latest capacity information and charge cycle counts.
If the battery is disconnected from the vehicle, the disconnect date and power levels when detached.
The full battery manufacturer detail including chemical composition, guidance, warranty.
A grade (A-F) for each battery that summarises the batteries future potential.
Detailed history of the battery for any issues and fixes similar to a vehicle service history.
