This Tadiran 1550A is a tagged 3.6V HLC. HLC’s (Hybrid Layer Capacitors) are a special type of rechargeable battery. They are used as a capacitor in PulsesPlus batteries, where they are connected in parallel to Tadiran Lithium Batteries.
These cells have low impedance and can deliver high current pulses. The performance and reliability properties of HLC’s have been carefully optimized to match those of Tadiran Lithium Batteries. The result is a battery pack with maximum energy and power density for stand alone use of up to 25 years.
Note: HLC’s need to be purchased in conjunction with Tadiran primary lithium cells and cannot be sold separately. If you are interested in HLC’s please contact us.
