We have applied six certificates, such as UL, CE, ROHS, REACH, BIS, CB, CCC for 12 models of our battery cells, such as 2500mAh, 3000mAh, 3200mAh, 3300mAh, 3400mAh, 3500mAh, 3600mAh, 3700mAh, 3800mAh, 4000mAh, 5000mAh, 5500mAh.  Then we use these battery cells to make our ups battery pack, so our ups battery performance excellent.

Each model battery certificates looks similar, if we upload all 72 certificates on this website, page would be too long and loading slow and a lot of certificates looks similar, easy confuse customers, so we upload some of our certificates here only . if you are interested in any model capacity battery cells and need its all certificates for reference, conact us, we would send certificates and reports  for your reference.
