The ASOL 523450 is a 1000mAh ultra-flat lithium polymer battery engineered specifically for instrumentation, smart cards, and portable medical devices. With a distinctive flat-wide form factor (52.5mm long × 34.5mm wide × only 5.3mm thick), this cell fills a unique niche between standard prismatic cells and custom-shaped batteries — offering a naturally flat profile that aligns with the internal cavity dimensions of digital meters, diagnostic instruments, and card-form electronic devices.
At 1000mAh (3.7Wh) with a clean 200mΩ internal resistance, the 523450 delivers stable, low-noise power essential for precision measurement equipment and medical diagnostics where voltage stability directly impacts accuracy. Its -20°C to +60°C discharge temperature range exceeds consumer-grade LiPo standards, making it suitable for field-deployed instruments and medical devices that must operate reliably across diverse environmental conditions.
