SDi CELL03KT Cell Checker for Testing Fire and Security Alarm Systems with Custom Case

Ensure your fire and security alarm systems stay powered when it matters most with the SDi Fire Cell Checker battery tester kit. This battery tester uses genuine pulse-load technology to measure a battery's ability to maintain voltage under load—giving you a true assessment of remaining capacity and health rather than a simple voltage readout. Designed for SLA batteries and supporting 2V, 4V, 6V, 8V and 12V units up to 200Ah, the CELL03KT delivers actionable results in approximately 15 seconds so on-site technicians can quickly replace weak cells and avoid service interruptions. Compact and supplied in a custom hard case, the kit is built for fieldwork across fire panels, alarm monitoring, surveillance power supplies and other low-voltage security installations. Reduce false alarms, extend maintenance efficiency, and improve uptime for critical monitoring systems. Add the SDi Fire CELL03KT Cell Checker to your toolkit to validate backup power and keep security and life-safety equipment reliable.
