The fully decoded chip ensures drop-in compatibility with existing charging circuits. ISO9001, RoHS and CE certifications confirm manufacturing quality.

Suits owners of listed BIG BEAM units needing

Installers who can match the exact model or part number will find a direct fit. Buyers with different emergency-lighting brands or unrelated voltages should look elsewhere. The pack requires careful connector alignment during installation. No charger is included in the package.

800mAh capacity powers supported fixtures

The 5.76Wh energy reserve handles standard emergency-lighting run-times specified by the original equipment. Heavy-duty or extended-duration units that demand higher watt-hour ratings will exceed this cell’s headroom. Physical dimensions of 98.20 x 43.00 x 14.60mm limit use to compartments sized for the original pack.
