Product Description
When your industrial equipment, security system, or utility meter needs a battery that won't quit, the COMP-ER14250-WL delivers. This 3.6V lithium battery in the compact 1/2 AA size comes pre-fitted with 6-inch wire leads for fast, flexible installation — no battery holder required. It's a direct replacement for the SAFT LS14250, ER14250, and a wide range of compatible part numbers, so swapping it in is simple.
Built for the Long Haul
The COMP-ER14250-WL uses Lithium Thionyl Chloride (Li-SOCl2) chemistry — the gold standard for long-term, low-drain applications. With a capacity of 1,200mAh and a self-discharge rate of less than 1% per year, this battery holds its charge for up to 10 years in storage. That means you can stock up without worrying about shelf life, and trust that the battery will be ready to perform when you need it.
One of the standout qualities of this chemistry is how it handles discharge. Unlike standard alkaline batteries that gradually lose voltage over time, this lithium cell maintains a stable output throughout its entire discharge cycle. For equipment that requires a consistent 3.6V to function properly — like PLCs, programmable controllers, and industrial sensors — that stability is not a nice-to-have, it's a necessity.
Performs Where Others Fall Short
Extreme temperatures are no problem for the COMP-ER14250-WL. It operates reliably across a range of -76°F to +185°F, making it a solid choice for outdoor meters, remote monitoring equipment, and industrial environments where temperature swings are part of the job. Whether it's installed in a cold-weather utility enclosure or a warm industrial panel, this battery keeps running without missing a beat.
The Wire Leads Make the Difference
The 6-inch wire leads on this battery are what set it apart from standard button-top or flat-top versions of the ER14250. They're designed for applications where direct soldering or wiring to a circuit board is the most practical connection method. This is especially useful in:
- PLCs and programmable logic controllers
- Utility and smart meters (water, gas, electricity)
- Memory backup and real-time clock circuits
- Security and alarm systems
- Tracking and telematics devices
- Remote sensors and industrial monitoring equipment
If your device previously used a SAFT LS14250 with leads, a Tadiran TL-5902, or any of the other compatible part numbers listed below, the COMP-ER14250-WL is a straightforward drop-in replacement.
A Replacement You Can Count On
Battery Mart stocks the COMP-ER14250-WL because we know how important it is to have the right battery available when your equipment needs it. This is a non-rechargeable primary cell — use it, and when it's done, replace it. There's nothing to charge and no memory effect to worry about. Simple, reliable, and ready to work.
Frequently Asked Questions
What devices is the COMP-ER14250-WL compatible with?
A: This battery is a direct replacement for any device that uses an ER14250 or LS14250 battery. Common applications include PLCs, utility meters, memory backup circuits, security and alarm systems, GPS and tracking devices, and remote industrial sensors. It also cross-references to part numbers including the SAFT LS14250, Tadiran TL-5902, TL-5101, TL-2150, Maxell ER3S, Xeno XL-050, and many others.
What does "WL" mean in the model number?
A: "WL" stands for Wire Leads. This version of the ER14250 battery comes with 6-inch wire leads already attached, making it easy to connect directly to a circuit board or wiring harness without needing a battery holder or separate adapters.
Is the COMP-ER14250-WL rechargeable?
A: No, this is a non-rechargeable primary lithium battery. It is not designed to be recharged and should be replaced when depleted. Attempting to recharge a primary lithium cell can be dangerous and will damage the battery.
How long will this battery last in storage?
A: The COMP-ER14250-WL has a shelf life of up to 10 years. Its Lithium Thionyl Chloride chemistry self-discharges at less than 1% per year, so it holds its charge well over time. For best results, store it in a cool, dry location away from direct sunlight.
What temperature range can this battery handle?
A: This battery is rated for operation between -76°F and +185°F. That makes it well-suited for outdoor installations, industrial environments, and other applications where temperature extremes are a factor.
Will this battery work as a direct replacement for my SAFT LS14250?
A: Yes. The COMP-ER14250-WL is an exact equal for the SAFT LS14250 with leads. It matches the same 3.6V nominal voltage, 1,200mAh capacity, and 1/2 AA form factor. Just verify that your device uses a version with wire leads rather than a button or flat top before ordering.
