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 standard Lithium Polymer expectations, making it suitable for field-deployed instruments and medical devices that must operate reliably across diverse environmental conditions.
Form Factor Comparison — Why the Flat-Wide Shape Matters
| Feature | ASOL 523450 | Standard 1000mAh Round Cell | Standard Prismatic (e.g., 703048) |
|---|---|---|---|
| Dimensions | 52.5 × 34.5 × 5.3 mm | Dia.20×H3.2mm (coin) or larger | 48×30×7 mm typical |
| Thickness | 5.3mm (ultra-flat) | N/A (cylindrical) | 6~8 mm |
| Width | 34.5mm (wide-flat) | N/A | 25~30 mm |
| Shape Profile | Flat rectangular slab | Cylinder / Coin | Block / Brick |
| Best For | Meters, Cards, Instruments | Wearables, small IoT | General portable electronics |
| Cavity Match | ✓Wide instrument bays | Too small / wrong shape | May not fill wide cavities |
Key Insight: Most 1000mAh Lithium Polymer cells are designed in “tall-narrow” configurations (~25mm wide). The 523450’s 34.5mm width makes it uniquely suited for wide-shallow device cavities found in digital multimeters, clamp meters, smart card enclosures, and handheld diagnostic tools.
Temperature Capability Comparison
| Operating Range | Typical Use Case | 523450 Support |
|---|---|---|
| 0°C ~ +45°C (Charge) | Indoor consumer charging | ✓Full support |
| -20°C ~ +60°C (Discharge) | Field instruments, outdoor medical, cold-chain logistics | Exceeds standard (-20~+55°C) |
| >+45°C ambient (Hot climate) | Desert / tropical deployment | ✓Up to +60°C safe discharge |
