Defibtech 5 Yr Battery Pack

The Defibtech 5-Year Battery Pack is the standard-life replacement battery for Lifeline AEDs. Once installed, it provides 8 hours of continuous operation or up to 125 shocks, with daily through quarterly self-tests confirming readiness. The 5-year shelf life is the entry-point battery — lower upfront cost than the 7-year, with one extra changeover required across a 10-year ownership period.

Frequently Asked Questions

Should I switch to 7-year batteries when this one expires?
If your site has reliable maintenance procedures and you'd rather minimise battery swaps, yes. If you're price-sensitive on each replacement and have good calendar reminders, the 5-year remains a reasonable choice.

Do I have to use the same battery generation as the original?
5-year and 7-year batteries are both Lifeline-compatible — you can switch between them at replacement time.

What happens if I forget to replace it on time?
The AED's self-test will flag battery expiry as a status warning. Replace immediately when this occurs — an expired battery may fail at the moment of rescue.
