Purpose & Fit

Energizer E90BP-2 supplies two 1.5 V alkaline button cells in the N-E90 size. They deliver a rated 300 mAh capacity and operate from 0 to 131 degrees F. The 0.43 in diameter by 1.12 in height matches devices specifying LR1, AM5 or MN9100 cross-references. Cameras and similar electronics are the listed application.

Who It Suits

Buyers replacing N-size button cells in cameras, meters or medical devices that call out 4001, 810, 910A or UM-5 equivalents will find a direct match. It is not for equipment requiring larger cylindrical cells or rechargeable chemistries. Devices needing a different voltage or terminal style should look elsewhere.

Deciding Spec

The critical figure is the 1.5 V nominal voltage combined with the N-E90 form factor; only cells sharing both the exact diameter and height will seat and contact correctly in the target device.

Questions about this item

How can I confirm the 1.5V N-E90 alkaline button cell is working correctly after inserting it into my camera?

Measure the open-circuit voltage with a multimeter; a fresh cell should read close to 1.5V, and the camera should power on and operate normally within the 0 to 131°F temperature range.

What comes in the 2-pack and do I need any extra accessories for installation?

The pack contains two N-E90 alkaline button cells with 300mAh capacity each; no additional accessories are required as they install directly into the device's button-terminal compartment.

Which version should I choose if my device lists cross-reference numbers 4001, 810 or 910A?

Select this N-E90 1.5V alkaline 2-pack; it replaces 4001, 810, 910A, AM5, LR1, MN9100 and UM-5 cells, delivering 300mAh capacity in the standard 0.43in diameter by 1.12in height size.
