Defibtech 7 Yr Battery Pack

The Defibtech 7-Year Battery Pack is the longest-life replacement battery for Lifeline AEDs. Once installed, it delivers 16 hours of continuous operation or up to 300 shocks, with daily, weekly, monthly, and quarterly self-tests confirming readiness. The 7-year shelf life means fewer changeovers across the AED's 8-year warranty period — the lower-maintenance choice for set-and-forget locations.

Frequently Asked Questions

7-year vs 5-year battery — what's the trade-off?
7-year battery costs more upfront (AU$546.90 vs AU$445.45) but means one fewer changeover over 14 years of ownership. Total cost is broadly comparable; choose based on whether you'd rather pay more upfront or take on the operational hassle of an extra battery swap.

Does this fit the VIEW or PRO Lifeline?
No — the VIEW and PRO use a different battery pack (DCF-2003, 4-year). This 7-year battery is for the standard Lifeline AED only.

Can I use a third-party battery?
Don't. Non-genuine batteries can void your AED warranty and may fail self-tests. Always use Defibtech OEM.
