Frequently Asked Questions

Basic Parameters

The LR44 battery has a mini size of 11.6mm diameter × 5.4mm height. It offers a standard voltage output of 1.5V. There are two chemical types:

This dual version design helps users choose based on device needs. For example, a glucometer is better with the silver oxide version to keep accurate readings.

Performance Comparison (Visual Data)

Laboratory test data shows:

• Energy Density: Silver oxide version is 33% higher than alkaline (200mAh vs 150mAh)
• Temperature Adaptability: Still works at 85% efficiency in -10°C
• Self-Discharge Rate: After 1 year, over 90% power remains

First Choice for Small Devices

From student calculators to home kitchen scales, LR44 fits over 20 types of devices with its standard size:

• Laser pointer runs for 120 hours
• Digital thermometer needs only one change per year
• LED flashlight gives steady light

Medical-Grade Safety

The mercury-free version is ISO13485 certified:

Medical Device Compatibility List:

• Hearing Aid: Works for 400 continuous hours
• Glucometer: Error rate <0.5%
• ECG Monitor Accessories: Strong anti-interference

General vs. Professional Use

Comparison tests show:

• Compatibility: Can replace 6 models like AG13/SR44
• Stability: Silver oxide version has voltage fluctuation <±2% (zinc-carbon battery up to ±15%)
• Economy: Daily cost only 0.03 CNY (based on 2-year use)

Eco-Friendly Innovations

Uses a triple protection design:

• Steel Shell Leak-Proof Technology: Lowers leak rate to 0.01%
• Mercury-Free Electrolyte: RoHS (Restriction of Hazardous Substances) certified
• Recyclable Structure: Over 95% metal recovery rate

Three Steps for Installation and Maintenance

1. Use a cotton swab to clean battery contacts
2. Place with the positive (+) side up
3. Do not mix old and new batteries

Storage Tips

• Ideal conditions: Temperature 15–25°C, humidity <60%
• Avoid contact with: Metal objects / liquids / fire sources

Choose the best option based on your device needs:

• High Precision → Silver Oxide Battery (e.g., SR44)
• Daily Use → Alkaline Battery (e.g., AG13)
• Temporary Backup → LR43 (110mAh capacity)
• Long-Term Use → Rechargeable Set

Are LR44 batteries the same as 357?

Both LR44 and 357 batteries share identical dimensions (5.4mm diameter × 11.6mm height). The 357 model uses silver oxide chemistry with a nominal voltage of 1.55V, whereas the LR44 employs alkaline technology rated at 1.5V. Silver oxide batteries typically deliver 30% to 100% longer service life and maintain more stable voltage output throughout their lifespan. Their discharge endpoint occurs at 1.2V, compared to alkaline batteries which drop to 1.0V at depletion. The silver oxide variant demonstrates superior voltage consistency until complete discharge.

What are LR44 batteries used for?

LR44 batteries are commonly utilized in numerous compact electronic gadgets and playthings, such as gaming devices, miniature toys, and various entertainment-oriented electronics.

Is the LR44 battery rechargeable?

The LR44 lithium battery is not designed for recharging. As a primary (single-use) cell, it's intended to be discarded once fully depleted. Recharging attempts may lead to hazardous consequences, including electrolyte leaking, rupture, or potential harm to both the cell and the equipment it operates. Unlike rechargeable batteries, its chemistry isn't compatible with energy restoration processes.

What batteries are compatible with LR44?

Appropriate substitutes for the LR44 battery include the Duracell 76A, Energizer A76, and AG13 cells. These models share identical specifications with the LR44, differing solely in their manufacturer-assigned designations. All listed batteries are fully compatible and may be employed interchangeably in devices requiring LR44 power sources.
