Medical Device Battery Certification

UN Transportation testing UN/DOT 38.3 - Mandatory

UL-1642: Lithium Batteries - Focus on single-cells - Used for evaluation

of Lithium-Metal (Primary) or of Lithium-Ion (Rechargeable)

UL-2054: Household and Commercial Batteries - Focus on Portable

Batteries - Typically Battery Packs - References UL 1642 for Lithium

Cells

IEC-60086 - Primary Batteries (Non-rechargeable) - Covers Performance

and Safety - IEC-60086-4 For Lithium (Primary) battery safety

IEC-62133 - Secondary Batteries (Rechargeable) - Focus on Lithium-ion

Batteries - First Edition, October 2002 - Second Edition released:

December 2012

FDA – No Battery Approval Guidelines for Implantable

Batteries“In terms of guidance unfortunately we don’t have a

published guidance yet. However we have recognized 3

battery related standards that deal with battery safety (IEC

62133 and UL 2054 and UL 1642) and are good indicators

of the types of tests we expect to see to demonstrate

medical battery safety. Thus, if a medical device battery

conforms to either 62133 or 2054 then the test report can

provide us with the needed assurance for battery safety.

As for performance, this will probably require additional

knowledge of the host device that utilizes the battery.

Silver Oxide Batteries• 1.5V cells

• Battery made from 2-3 button cells (SR44…)

• Operating time 12- 40 hours

• Current consumption of constant uA & mA pulses

• Low cost (consumer cells)

• No transportation regulations

• FDA approval

• Some cell types has High energy and power

• Proven success stories (Given Imaging, Drug injectors..)

Miniature Cylindrical Lithium Cells for Microelectronic Pills

• Conventional hard case cells

• Max size of 11.6mm diameter over 10.8 length – But

smaller diameter is preferred

• Primary cells – High energy but low power

• Rechargeable cells – Low energy but high power

• Very few on the shelf solutions

• Costly custom made solutions
