Battery Holder Testing & Compliance

Design And Testing, ANSI, EIA, UL.

For testing new designs of battery holders, MPD has fabricated min-max sized battery slugs. The slugs are a great aid to our engineering staff in several ways:

The minimum - maximum, length and width for common batteries is fairly wide.

  Length Height

D cell 59.5 61.5 32.3 34.2
C cell 48.5 50.0 24.9 26.2

IEC-ANSI standards

UL2069: Issue number 2, October 2001

This UL standard determines if batteries are properly retained by a holder. 50 insertion-extractions of the battery are followed by contact retention, conditioning, vibration and jarring tests. Notable in the test procedure is temperature conditioning with unplated copper slugs.

Coin cell battery holder in 60" drop test fixture per UL2069

We used wing nuts for quick mounting of the same PCB to either the jarring or drop test fixtures. Top

UL2069 Jarring test fixture

PCB is mounted on rear side of 3/4" thick plywood board and struck by 2" steel sphere


UL2069 Jarring test fixture mounted vertically

For vertical test the 2" steel sphere is dropped down a tube. Battery holder is mounted on rear of same board mounted horizontally.


EIA Specification number, EIA-540J000

The purpose of the specification is to provide standard test methods, gages and performance requirements for battery holders. Tests vibration, shock, contact resistance, solderability, temperature/humidity
The major difference between the UL & EIA tests is that continuity is continually monitored during vibration and mechanical shock in the EIA specification. Minor differences are contact resistance and solderability requirements. The EIA also has separate requirements for coin cell holders and cylindrical battery holders, under EIA-540J0AA & EIA540JAB.


ASTM F963, Toy Safety

Coin cell batteries are specifically exempted from the requirements. Limited requirements for a battery holder as the standards focus is on markings, circuit protection, harness wiring and limiting access to batteries without tools. Minor requirements for the battery holders connectors and wires flammability rating, V-0 and insulation heat resistance.



Intrinsically safe apparatus, ANSI/UL. If you need to meet this requirement, contact our engineering dept or a professional industrial designer or engineering company.

Product Safety Compliance

Batteries are considered safety critical components by compliance laboratories. A properly designed circuit with reverse current charging protection of lithium batteries is required, typically two blocking diodes in series or a voltage blocking component plus a current blocking component (diode-resistor combination). Plastic components like battery holders have safety requirements when part of a circuit containing any kind of battery or battery charging circuits. MPD's drawings contain the necessary information to make your collecting of documentation for product safety easier.
