Uniross ML1225 lithium-aluminium rechargeable coin cells deliver 28 mAh at 3V in a 12.5mm diameter, 2.5mm profile — 56% more capacity than the ML1220 in the same footprint diameter with a marginally increased 0.5mm height. The ML1225 is the preferred specification for 12.5mm rechargeable coin cell sockets where maximum energy storage is the design objective and the 2.5mm height is mechanically acceptable. Rated for 300 cycles at 10% DOD and operating reliably from -20°C to +60°C, it is suitable for OEM embedded systems, backup power applications, and any 12.5mm rechargeable coin cell socket requiring extended cycle life. Available in bulk from European stock.
