Always match your device's battery model (ER14250) and voltage (3.6V) before ordering. - BUILT FOR COLD TEMPERATURES & OUTDOOR DEVICES: Wide operating temperature range of -55 Degrees C to +85 Degrees C (-67 to 185 Degrees F) keeps voltage output stable in freezing basements, outdoor pet fence collars, garage sensors and attic alarm components where ordinary AA alkaline batteries fail. - 10-YEAR SHELF LIFE, UNDER 1% SELF-DISCHARGE PER YEAR: Low self-discharge Li-SOCl2 chemistry means these batteries hold their charge in storage and in standby devices — a full 1200mAh per cell ready when your meter, alarm panel or sensor backup needs it. Store clean, dry and below 30 Degrees C. - NOT RECHARGEABLE — 3.6V PRIMARY LITHIUM, NOT A 1.5V AA SUBSTITUTE: These are single-use lithium thionyl chloride cells. Never place them in a charger, and never use them in devices designed for standard 1.5V AA alkaline batteries — the higher voltage can damage the device. - FRESH STOCK & ACTIVATION SUPPORT:Like all Li-SOCl2 batteries, ER14250 cells may show slightly low voltage after very long storage (passivation) — this is normal chemistry, not a defect, and full output returns within minutes under load.
