Replacement and Installation Steps
The L1154F is a common lithium primary (non-rechargeable) button cell battery. It is made for small electronic devices. Its main advantages are its lightweight design and high energy density. It can power devices like watches and calculators for many years. Compared to nickel-metal hydride (NiMH) batteries, it needs fewer replacements and works well in low-power situations. It also helps devices stay reliable in standby mode, giving users peace of mind.
The L1154F has great features: low power use, long life, and a maintenance-free design. Compared to normal alkaline batteries, it lasts longer with the same size. It has a capacity of up to 220mAh and a self-discharge rate under 5%. This means it can stay in storage for 10 years without much loss. Its small 20mm diameter makes it easy to fit into devices. Users won’t need to worry about installation. Compared to the CR2032, the L1154F weighs only 3.0g—lighter and easier to carry.
The name “L1154F” follows an industry standard code. “L” means lithium chemistry, “1154” shows the exact size—about 20mm in diameter and 3.2mm thick. “F” stands for a special version series. This naming style is clear and helps users tell it apart from other batteries.
The L1154F has a size that fits many devices. The 20mm diameter fits watch slots well, and the 3.2mm thickness saves space. It follows ISO standards, so it’s easy to use in portable calculators or motherboard battery holders. This makes device assembly easier.
Key specs include a nominal voltage of 3V and a rated capacity of 220mAh. The 3V voltage gives strong power. Its capacity is higher than other same-size button cells—for example, the BR2025 only has 165mAh. Imagine a bar chart: the L1154F’s voltage line stays flat and strong, and the capacity bar is 20% higher than others. This shows its great performance in small devices.
The L1154F stands out with great performance. Under full load, it keeps more than 95% of its voltage. It works in wide temperatures, from -20°C to 60°C, and stays reliable in very cold weather. Its yearly self-discharge rate is under 5%, much better than the average 10%. This means it has a very long standby life.
Main advantages include light weight (only 3.0g), safety, and eco-friendly materials. Unlike lead-acid batteries, it has a stainless steel case with short-circuit protection, which stops leakage risks. The materials are 100% recyclable, giving users a green option. Because it’s safe, it is used in many medical devices to protect user health.
In consumer electronics, the L1154F is perfect for watches and calculators. It can give power for 1 to 2 years without a break. Compared to regular batteries, it lasts 30% longer in small devices, so users change batteries less often. Think of your fitness band: this battery lets it run for 500 days with no drop in performance, helping you record data smoothly every day.
As a motherboard BIOS battery, the L1154F keeps system settings safe and stable. It fits many slot designs and is easy to install. Unlike nickel-cadmium (NiCd) types, it has no memory effect, which helps the hardware last longer.
In medical tools or small IoT (Internet of Things) devices, it is easy to use. Wireless sensors use its small size for long-term monitoring. For example, a medical pulse oximeter can work 12 months with an L1154F, and the data stays 99% accurate. That is a big advantage.
Similar options include CR2032 and BR2032 (high-temperature type). Both use lithium chemistry. But the L1154F is a little better in capacity (220mAh vs. 210mAh) and low-temperature stability. Its data sheet shows a 0.5% lower self-discharge rate, making it better in harsh conditions. This shows its high value for the price.
Special replacements like Panasonic CR2032H or Sony CR2032 can be used. But the L1154F works with more brands and fits better. Imagine a radar chart: the L1154F’s compatibility score covers the largest area, proving its wide use advantage.
| Specification | Value/Description |
| Nominal Voltage | 3V |
| Rated Capacity | About 220mAh |
| Size (Diameter x Thickness) | 20mm x 3.2mm |
| Chemistry Type | Lithium-Manganese (Li-MnO₂) |
| Weight | About 3.0g |

Extra info: the positive terminal uses manganese dioxide (MnO₂) structure, and the stainless steel case gives more durability. The packaging is eco-friendly and easy to recycle. Imagine a glowing data grid: red and green lights show spec values, and the 10-year shelf life shines green, showing long-term reliability.
Before replacing, make sure it’s safe. Power off the device and use anti-static tools to avoid damage. This takes only 30 seconds and helps prevent short circuits. Compared to more complex lithium batteries, you don’t need special tools, so it’s easier to handle.
A simple 3-step guide:
The whole process takes less than 2 minutes. Think of your car key remote: the L1154F easily replaces the old battery and brings back quick control.
Key points: don’t install it the wrong way (positive side must face up), and keep contact points clean. Use a magnifying glass if needed for small devices. Compared to other models, the L1154F has only 1% install error, thanks to user-friendly design.
The future may bring rechargeable lithium button cells with 20% more energy and better cold-weather performance. These upgrades will follow L1154F’s strengths and support smarter devices.
Driven by the Internet of Things, demand is expected to grow 15% each year. Green rules will also push for more recyclable materials. L1154F leads this green change. Imagine a bar chart for 2025: eco-friendly score reaches 90%, much higher than the industry average.
In terms of function and specifications, the L1154F battery is indistinguishable from the LR44. Both are compatible button cell types suitable for substitution.
he LR44 battery, also known as the AG13, 357, or L1154F, is a 1.5V alkaline button cell commonly used in small electronic devices.
The L1154F is a common alkaline coin cell battery with standard dimensions of 11.6 mm × 5.4 mm. It is compatible with and serves as a direct replacement for LR44, AG13, and 357A batteries.
