Understanding AED Battery and Pad Life and Self‑Testing

By November 14, 2025No Comments

When investing in an automated external defibrillator, you want a device that stays ready without constant oversight and expensive yearly servicing plans.

 

The ZOLL AED Plus leads the market with long battery and pad life and robust self‑testing.

Battery Life

  • The AED Plus uses ten lithium batteries that typically last five years or 225 shocks, longer than many competitors.
  • Batteries can provide up to 13 hours of continuous monitoring, ensuring the device remains powered throughout prolonged emergencies.
  • The batteries are a consumer grade Duracel CR123 lithium battery, making them readily available from us, or from electronics stores – don’t get stuck with a competitor’s AED who cannot source replacement batteries for you (yes we’ve heard this happen many times!)

Electrode Pad Life

  • The AED Plus’ adult CPR D-Padz electrodes have a 5 year life. Like all AEDs, the pads are a one-time use item and must be replaced once opened and used in a rescue.

Self‑Testing Features

  • A configurable automatic self‑test runs every one to seven days and performs a monthly full‑energy discharge
  • The tests verify battery capacity, electrode connection, ECG circuitry, CPR circuitry and audio systems
  • A simple “Red X” indicator alerts owners when service is needed, eliminating guesswork.

Maintenance Best Practices

  • Check status regularly – a quick glance at the status window tells you if the AED is ready.
  • Replace batteries and pads on schedule – the long life of ZOLL components means fewer replacements, but mark calendar reminders to ensure compliance.
  • Store in a visible, accessible place – proper placement and signage reduce response time.

Key Benefits of the ZOLL AED Plus

  • Industry‑leading battery life – five‑year battery and pad life minimises downtime and costs.
  • Comprehensive self‑testing – automatic diagnostics keep the device reliable without manual checks.
  • Low cost of ownership – fewer consumables and replacements save money over the device’s life.
