AG10 Battery vs LR44

Size

There is a big size difference between these batteries. Both have a diameter of 11.6 mm, so they look alike at first. The main difference is how thick they are. The AG10 Battery is about 3.1 mm thick. The LR44 is much thicker at 5.4 mm. Because of this, the LR44 will not fit in every device that uses an AG10 Battery. If your device has a small battery space, the LR44 might not fit.

Tip: Always check how thick the battery is before you swap. Using a thicker battery can break your device.

Voltage & Capacity

Both batteries give 1.5V of power. This means they can run similar electronics. The big difference is in how much energy they hold. The AG10 Battery usually has 65-72 mAh. The LR44 can hold 110-150 mAh. The LR44 lasts longer in things that use more power.

Note: LR44 batteries last longer because they store more energy.

Performance

Both batteries work well in low-power gadgets. The LR44 is better for things that need more power or run longer. The AG10 Battery is best for devices that use less energy and have small battery spaces. If you try to use an LR44 in a spot made for AG10, it might not fit. The battery cover could stick out. Always use the right battery for your device.

Applications

The AG10 Battery is used in calculators, digital watches, key fobs, and small toys. These things need a thin battery and do not use much power. The LR44 is found in watches, calculators, thermometers, cameras, remotes, and hearing aids. Devices that need more power or have bigger battery spaces use the LR44.

Remember: Both batteries are alkaline, but you cannot always swap them. Always check your device’s manual before changing batteries.

Choosing the Right Substitute

Tips

Picking the right battery helps your device work well and last longer. Here are some easy steps to follow:

1. Make sure the voltage is 1.5 volts. This keeps your device safe.

2. Check the size and how much power it holds. The battery must fit and give enough energy.

3. Look at your device’s manual. It tells you which batteries work best.

4. Check your old battery for numbers and letters. These show the model, voltage, and power.

5. Use charts to compare batteries. They help you find ones that are the same.

6. Buy batteries from stores you trust. This way, you get real batteries that work well.

7. Watch for small changes in size or power. Even little differences, like between LR54, LR1130, or G10A, can change how your device works.

8. Think about what the battery is made of. Silver oxide batteries last longer and keep power steady, but they cost more.

9. Put the battery in the right way. Match the plus and minus sides and be gentle with the contacts.

You can use AG10-sized batteries like LR54 or 389 in many devices. If your device has a small space, pick a thinner battery. If you want it to last longer, a thicker battery like LR1130 might be better. Knowing these things helps your device work its best and last longer.

Safety

Always be careful when you use button cell batteries:

• Keep batteries away from kids and pets. They could swallow them.

• Put each battery in its own plastic bag or cover the ends with tape. This stops short circuits.

• Do not throw batteries in the trash or recycling bin. Take them to special battery recycling places.

• Be extra careful with lithium batteries. Broken batteries or touching the ends can cause sparks or fire.

• Follow all rules from the maker or your local waste center when you throw batteries away.

• Only use new batteries with the same type and voltage as the old one.

• If someone swallows a battery, get help from a doctor right away.

• Always look at the battery for safety notes and how to use it.

Safety first: Handling and throwing away batteries the right way keeps you, your family, and the earth safe.

You have several great options when replacing your battery. The most recommended substitutes include:

• LR1130

• LR54

• 189

• G10A

• LR44 (for devices with larger battery slots)

For calculators, watches, key fobs, and toys, LR1130, LR54, 189, and G10A work best because they match the size and voltage. To choose the right battery:

1. Check your device manual or old battery for the correct code.

2. Buy from trusted brands like Energizer or Maxell.

3. Make sure the voltage and size match your device.

Always follow safety tips and dispose of old batteries properly.
