Product Description

When reliability isn't optional, the Saft LS9V is the battery for the job. This 9 volt lithium battery brings industrial-grade performance to the devices that need it most — smoke detectors, security systems, memory backup units, and a wide range of professional electronics. Built to Saft's exacting standards, the LS9V is engineered to keep working when it matters most.

Ready When You Need It — For Up to 10 Years

One of the standout advantages of the LS9V is its remarkably low self-discharge rate. Where a standard alkaline 9V slowly loses its charge just sitting on a shelf, the LS9V holds onto its power for up to 10 years in storage. That makes it an ideal choice for emergency preparedness kits, backup devices, and any situation where a battery may sit unused for an extended period. Stock up with confidence — it'll be ready to go when you reach for it.

Performs in Conditions That Would Sideline an Alkaline

The LS9V is rated for use across an impressive temperature range: -76°F all the way up to +185°F. That kind of range opens the door for use in environments where standard batteries simply fall short. Consider applications like:

  • Outdoor security systems exposed to cold winters
  • Equipment stored in hot attics or utility rooms
  • Industrial electronics operating in demanding conditions
  • Professional and medical devices requiring consistent performance

Whether it's a bitter cold snap or sweltering summer heat, the LS9V maintains stable, reliable voltage output throughout.

More Capacity Means Fewer Replacements

At 1,200 mAh, the LS9V offers significantly more capacity than a typical alkaline 9V battery, which usually tops out around 500–600 mAh. In practical terms, that means longer run times and fewer battery swaps. For devices installed in hard-to-reach locations, or in life-safety applications where you want maximum time between service visits, that extra capacity is a real advantage.

A Simple, Drop-In Fit

The LS9V uses standard battery snap contacts, so installation is exactly what you'd expect from any 9V battery — no adapters, no special tools, no hassle. It's also a direct replacement for several common part numbers, including the ER9V, LIS9V, LSC9V, P9VL, and U9VL.

Backed by a Brand That's Been Doing This for Over a Century

Saft has been manufacturing specialty batteries for more than 100 years, supplying power solutions to the military, aerospace, medical, and industrial sectors worldwide. The LS9V reflects that same depth of engineering expertise. When you need a battery you can trust in a device you can't afford to have fail, Saft is a name that has genuinely earned its reputation.

Frequently Asked Questions

What devices is the Saft LS9V compatible with?

The LS9V fits any device that uses a standard 9V battery with snap contacts. Common uses include smoke detectors, carbon monoxide alarms, home security and alarm systems, memory backup units, and a wide range of industrial and medical electronics. It also serves as a direct replacement for batteries listed under the part numbers ER9V, LIS9V, LSC9V, P9VL, and U9VL.

How does the LS9V compare to a regular alkaline 9V battery?

The LS9V outperforms alkaline in several important ways. It offers a much higher capacity (1,200 mAh versus roughly 500–600 mAh for a typical alkaline), retains its charge for up to 10 years in storage, and handles extreme temperatures that would cause an alkaline battery to fail. The upfront cost is higher, but for critical or hard-to-access devices, the extended life and reliability make it a smart long-term value.

Is the LS9V safe to use in smoke detectors and fire alarms?

Yes — the LS9V is well-suited for smoke detectors and fire alarm systems. Its stable voltage output and long shelf life make it a particularly strong choice for life-safety devices where consistent, dependable performance is non-negotiable.

Can I use the LS9V in a device that currently takes a standard alkaline 9V?

In most cases, yes. The LS9V uses standard snap-on terminals and installs the same way as any other 9V battery. That said, because its open-circuit voltage measures slightly higher than a typical alkaline 9V, it's worth checking your device's documentation to confirm it's compatible with lithium 9V batteries. Most devices handle it without any issues, but some sensitive electronics may specify alkaline-only use.

What does "lithium thionyl chloride" mean?

Lithium thionyl chloride (Li-SOCl2) is a battery chemistry prized for its high energy density and extremely long shelf life. It's widely used in professional, industrial, and medical applications where long-term reliability is critical. The LS9V uses a non-flammable electrolyte and is safe for standard consumer use.
