Our IECEx & ATEX Explosion-proof LED Light with Battery Backup uses Li-ion Batteries as the power supply in the emergency mode which is with larger capacity, higher density, and made with Japanese battery cells. Although this will increase the cost, we insist on the best design and quality!
Compared with traditional batteries, Li-ion batteries have almost no memory effect and can be quickly recharged at any time! Besides, the lower self-discharge rate is less than 5% to 10% per month.
The following video is the battery automatic production, sorting and quality inspection records. All the batteries we use have granted the UL2054 certification. We always provide you with the safest and guaranteed products!
