DBS system battery life and impedance limit.

DBS system company model	Battery type	Battery life (average)	Impedance limit for open circuit in ohms.	Impedance limit for short circuit in ohms
Medtronic Soletra™; (no longer manufactured)	Single chamber; Nonrechargeable battery	3 to 5 years	If it is >2,000 ohms for bipolar and corresponding monopolar configurations and current is less than 10 uamps then it is likely open circuit.	<250 ohms
Medtronic Kinetra™; (no longer manufactured)	Dual chamber; Nonrechargeable battery	3 to 5 years	If it is >4,000 ohms for bipolar and corresponding monopolar configurations and current is less than 10 uamps then it is likely open circuit.	<250 ohms
Medtronic Activa SC	Single chamber; Nonrechargeable battery	3 to 5 years	If it is 5000–9000 ohms for bipolar and corresponding monopolar configurations suspect possible threatened open circuit.; If it is >10000 ohms for bipolar and corresponding monopolar configurations then there is high suspicion of open circuit.; If it is >40000 likely there is fracture in system.	<250 ohms
Medtronic Activa PC	Dual chamber; Nonrechargeable battery	3 to 5 years	Same as Activa SC.	<250 ohms
Medtronic Activa RC	Dual chamber; Rechargeable battery	8 years	Same as Activa SC.	<250 ohms
St Jude Libra™; (no longer manufactured)	Single chamber; Nonrechargeable battery	3 to 5 years	High (31) is an open circuit.
Abbott Infinity 5™	Dual chamber; Nonrechargeable battery	3 to 4 years	>3000 Ohms.
Abbott Infinity 7™	Dual chamber; Nonrechargeable battery	4 to 5 years	>3000 Ohms.
