Energizer LR41	1.5V	Alkaline	Watches, small toys, calculators	Small (approx. 4.1mm x 7.9mm)
LR44 (AG13)	1.5V	Alkaline	Larger toys, scales, heavy-duty small devices	Slightly Larger than LR41 (approx. 5.4mm x 11.6mm)
CR2032	3V	Lithium	Computer motherboards, car fobs, medical devices	Thicker and wider than LR41 (approx. 3.2mm x 20mm)

How to Safely Replace Your Energizer LR41 Battery

Replacing a tiny battery like an LR41 is usually straightforward, but it’s important to do it carefully to avoid damaging your device or the new battery.

Step-by-Step Replacement Guide:

Identify the Battery Compartment: Look for a small screw, a clip, or a sliding cover on the back or side of your device. Sometimes it’s very hard to spot on watches.
Gather Your Tools: You’ll likely need a very small screwdriver (often a jeweler’s screwdriver or a tiny Phillips head) if screws are involved. For other compartments, you might need a small, flat, non-metallic tool like a plastic spudger or even a fingernail to gently pry open a cover. It’s best to avoid metal tools if possible to prevent scratching or short-circuiting.
Open the Compartment: Carefully unscrew any screws or gently pry open the cover. Store the screws in a safe place so you don’t lose them.
Note Battery Orientation: Before removing the old battery, pay close attention to which side is facing up. There’s usually a positive (+) side (often flat with markings) and a negative (-) side (often slightly domed or with a rim).
Remove the Old Battery: Gently slide out the old battery. You might be able to do this with your fingernail or a non-metallic tool. Be careful not to bend any metal contacts.
Insert the New Energizer LR41 Battery: Place the new Energizer LR41 battery into the compartment with the correct orientation. The positive (+) side typically faces upwards, but always double-check your device.
Close the Compartment: Carefully replace the cover and screw it back in place, or snap/slide it shut. Don’t overtighten screws.
Test the Device: Turn on your device to make sure the new battery is working correctly.

Safety First! Important Precautions:

Swallowing Hazard: Button cell batteries, including Energizer LR41s, are extremely dangerous if swallowed, especially by children. Keep them out of reach of young children and seek immediate medical attention if ingestion is suspected.
