Description
Tadiran XOL C 8.5Ah 3.6V Lithium (Li-SOCI2) Batteries (TL4920)
Forget About It
Would you like to install a battery that you won't have to change for a few decades? Then think Tadiran, who has a reputation for producing batteries that defy expectations. Here's an example: 25 years ago, these cells were selected to fuel an entire line of house-side electric meters, numbering over 3 million units. Today, utility companies are reporting that those meters are still running perfectly fine on their original Tadiran batteries. No recharges, no upgrades, no replacements. When you need a battery for your professional equipment, don't settle for a consumer cell.
Tadiran's XOL (eXtended Operating Life) Series is a long-life modification of their original TL cell, intended for extreme long-term operation and memory backup. We're talking decades. Lithium thionyl chloride cells feature the highest energy density and open circuit voltage (3.6V) of any battery chemistry. They're also known for their low self-discharge (1% per year). The XOL line has roughly 33% higher capacity than Tadiran's standard TL line.
You'll find Tadiran batteries powering a variety of lifesaving, infrastructure, and mission critical equipment, such as:
- Utility: AMR/AMI meters
- Medical equipment:
- Automatic external defibrillators
- Bone saws
- Infusion pumps
- Bone growth stimulators
