Jaycar 12V 6.5Ah Sealed Lead Acid Battery – UPS, NBN & Alarm Backup (2.2kg)

The NBN box just blinked off. The alarm panel's flashing a low-battery icon you've been ignoring for two weeks. Your UPS is running on fumes and you don't want to find out what it actually does during a blackout.

This Jaycar 12V 6.5Ah SLA battery is the backup cell that keeps those critical systems breathing. It's the kind of battery that sits quietly in your UPS, your NBN installation, or your alarm panel — and when the power dips, it picks up without you thinking about it.

Charge at 720mA for 10–14 hours (cycle voltage 14.4–15V at 25°C). It'll push a max discharge of 81A over five seconds when the system needs that surge. At 2.2kg it's a solid, sealed unit — no liquid, no top-up, no mess. Just reliable backup power for the gear you can't afford to lose
