LifePak 500 Lithium vs. Rechargeable SLA Batteries

Feature	LifePak 500 Lithium	Rechargeable SLA
Maintenance Requirements	Zero Maintenance	Regular charging schedules
Shelf Life	5 Years	2-3 years typical
Readiness	Always Ready	Requires charge monitoring
Weight	1.2 lbs (Lightweight)	3-5 lbs typical
Emergency Capacity	300 Shocks / 14 Hours	Variable based on charge

Optimal performance and safety guidelines:

• Shelf Life: 5 years when stored at proper temperatures
• Replacement Schedule: 3 years recommended for optimal performance
• Capacity Degradation: After 4 years with no use, approximately 35% capacity remains
• Temperature Limits: Do not expose to temperatures above 122°F (50°C)
• Storage: Store in cool, dry environment until installation
• Safety: Do not attempt to recharge - non-rechargeable design

How long will this battery last in my LifePak 500 AED?

With optimal maintenance, the battery provides 300 shocks or 14 hours of "ON" time when new. We recommend replacement every 3 years for optimal performance, though the battery has a 5-year shelf life when properly stored.

Why choose lithium over rechargeable SLA batteries?

Lithium batteries require zero maintenance, have longer shelf life (5 years vs. 2-3), are always ready for emergency use, and weigh significantly less. There's no risk of finding a dead battery during an emergency due to charging neglect.

Does the AED automatically test this battery?

Yes, the LifePak 500 AED automatically tests the lithium battery as part of its daily auto-test routine. It also performs a battery test when the AED is first turned on after installing a new battery.

What happens if I try to recharge this battery?

Never attempt to recharge this lithium battery. It's designed as non-rechargeable, and charging attempts can damage the battery permanently or create safety hazards. The maintenance-free design eliminates the need for charging.

How do I know when to replace the battery?

Follow the 3-year replacement schedule for optimal performance, monitor the AED's battery status indicators, and check the expiration date on the battery label. The AED will alert you to low battery conditions during testing.
