How to test the battery capacity without tester ?

Dear CSPower Valued Customers:

Share one method to test discharge capacity by yourself when receive the batteries from factory:

For example, the batteries you want to test is 12V 200Ah battery 

Firstly, charged the batteries to be full power, 

12v 200ah C10 battery , discharge the battery at 20A, could last 10 hours in ttotal, that means the batteries are full capcity.

12V 200ah C20 battery,  discharge at 10A , then could discharge 20 hours in total that means batteries are full capacity .

For tthe cspower batteries, every shipment, could share related battery discharge capacity test report when goods are ready for shipping for your order. We test all batteries well from lab.

More questions for the batteries, please feel free to recah us.

Best regards,

CSPower Team
