Battery Equivalents by Application
Choose the device class first—watches, key fobs, CMOS backup, hearing aids and more—then compare the battery codes, chemistry and replacement limits that matter.
Watch cells by size and chemistry
Cross-reference SR626SW/377, SR920SW/371, 357, L736, and other watch cells with silver oxide vs alkaline tips.
CR2032, CR2025, CR1632 and keyless entry replacements
Identify the coin cell in your car remote, garage transmitter, or smart key and find safe equivalents.
LR44, LR1130, L1131 and meter cell cross references
Find button-cell replacements for calculators, digital thermometers, calipers, and handheld meters, with voltage, size, and chemistry checks before swapping.
LR44, AG13, AA/AAA cells for toys and pointers
Find safe alkaline button-cell and cylindrical battery replacements for toys, laser pointers, and LED novelties by matching voltage, size, and chemistry.
CR2032 CMOS / motherboard backup cells
Replace a PC CMOS or RTC backup battery safely by identifying the correct 3V lithium coin cell, connector style, polarity, and physical fit.
Sizes 10, 13, 312, and 675 zinc-air equivalents
Match hearing-aid tab colors and zinc-air sizes — not interchangeable with silver oxide watch cells.
CR2450, CR2032 and clinical device battery notes
High-capacity coin cells used in monitors, thermometers, and portable medical electronics — with safety caveats.
CR123A, CR2, 18650 and photo/lighting replacements
Lithium cylindrical cells for cameras, security lights, and high-drain flashlights — with Li-ion safety notes.
CR2032, CR2025 and button cells for remotes and scales
Choose everyday battery replacements for TV remotes, digital scales, and small household electronics by matching voltage, size, chemistry, and device load.
Coin cells and cylindrical packs for low-power IoT
Choose CR2450, CR2032, AA, or lithium-ion battery packs for wireless sensors by comparing voltage, pulse load, capacity, size, and expected runtime.
