SDi CELL03 Lead Acid Pulse Load Battery Tester

Ensure reliable backup power for fire, security and surveillance systems with the SDi Fire CELL03 Lead Acid Pulse Load Battery Tester. Designed for technicians and maintenance teams, this battery tester evaluates a battery’s ability to deliver power under load — the true indicator of operational readiness — rather than relying on voltage alone. Using genuine pulse load technology, the CELL03 delivers clear pass/fail results in about 15 seconds, helping you quickly pinpoint weak or failing SLA and lead-acid batteries.

The CELL03 supports 2V through 12V batteries up to 200Ah, making it suitable for common alarm, monitoring and UPS battery banks. Portable and easy to operate, it streamlines preventive maintenance, reduces unnecessary battery replacements and ensures your security and monitoring equipment stays powered when it matters most. Note: while it can test lead-calcium batteries, larger stationary 2V flooded cells are not recommended for this handheld unit.

Add the SDi CELL03 to your toolbox to speed up diagnostics and improve system uptime — ideal for installers, service contractors and facilities managers responsible for security and surveillance power reliability.
