Features:
Long service time: Under normal condition and correct operate ion, LIR2450 battery can maintain 80% capacity after 500 cycles.
High energy density: Batteries are easy to meet the mini equipment, with small volume and lightweight.
High working voltage: About 3.6V working voltage, 3 times higher than NiCd or NiMh battery, it could reduce the amount of the battery needed.
No memory effect: Without memory effect, LIR2032 battery could provide you enough power whenever and wherever you are.
Good consistency: Manufacturing processes are under a strict control of ISO9000 quality control system, The capacity, internal resistance, discharge plateau and self-discharge of each battery has good consistency.
Safety: A built-in safety vent could prevent the cell from expose.
Money Saving: In most case, it can replace CR2450 Lithium primary button cell . One LiR2032 = 200 pcs CR2032
Optional: Solder-able Tabs are available in product option
