Medical device battery JWST480

medicallithiumcompact

<b>Overview</b><br>12V LiFePO4 (lithium iron phosphate) starter batteries from the JWST series, designed as lightweight rechargeable replacements for lead-acid starters on motorcycles, ATVs and small vehicles. ABS hard-case models provide compact dimensions and high cranking power.<br><br><b>Competitive Advantage</b><br><ul><li>Significantly lower weight and volume — about one third of equivalent lead-acid batteries</li><li>Fast recharge capability — supports high charge currents (up to 5C for cells)</li><li>Long cycle life — >2000 cycles (JISD standard) compared with 150–300 cycles for lead-acid</li><li>Maintenance-free and leak-proof — no liquid acid inside</li><li>Environmentally friendlier — no heavy metals such as lead, cadmium or mercury</li></ul><br><b>Description</b><br>Nominally marketed as 12V starter batteries (13.2V nominal cell configuration) offering superior cranking performance—typically up to twice the cranking power of equivalent lead-acid units. Cells use LiFePO4 chemistry for thermal stability and long service life. Units are supplied in robust ABS enclosures and are suitable for restricted-space installations.<br><br><b>Models (table)</b><br>JWST120 | Case: ABS | Nominal Voltage: 13.2 V | Capacity: 2.5 Ah | Max charge voltage: 14.4–14.6 V | Min discharge voltage: 8 V | Max charge current: 5 A | Max starter current: 120 A | Dimensions (mm): 113×70×85 | Weight: 590 g | PbEq: 7 Ah | Temp: -30℃–70℃ | Self-discharge: 1.5%/month | Recommended engine: <125CC<br>JWST240 | Case: ABS | Nominal Voltage: 13.2 V | Capacity: 5.0 Ah | Max charge voltage: 14.4–14.6 V | Min discharge voltage: 8 V | Max charge current: 10 A | Max starter current: 240 A | Dimensions (mm): 150×87×93 / 135×65×92 / 150×65×92 | Weight: 1000 g | PbEq: 10 Ah | Temp: -30℃–70℃ (one variant 30℃–70℃) | Self-discharge: 1.5%/month | Recommended engine: 125–250CC<br>JWST360 | Case: ABS | Nominal Voltage: 13.2 V | Capacity: 7.5 Ah | Max charge voltage: 14.4–14.6 V | Min discharge voltage: 8 V | Max charge current: 15 A | Max starter current: 360 A | Dimensions (mm): 150×87×105 | Weight: 1300 g | PbEq: 20 Ah | Temp: -30℃–70℃ | Self-discharge: 1.5%/month | Recommended engine: 500–1100CC<br>JWST480 | Case: ABS | Nominal Voltage: 13.2 V | Capacity: 10 Ah | Max charge voltage: 14.4–14.6 V | Min discharge voltage: 8 V | Max charge current: 20 A | Max starter current: 480 A | Dimensions (mm): 175×87×153 | Weight: 1900 g | PbEq: 35 Ah | Temp: -30℃–70℃ | Self-discharge: 1.5%/month | Recommended engine: >1100CC<br><br><b>Additional package sizes</b><br>4-cell 12V 2500mAh — 110×28×75 mm; 8-cell 12V 5000mAh — 110×55×75 mm; 12-cell 12V 7500mAh — 110×80×75 mm; 16-cell 12V 10Ah — 110×110×75 mm<br><br><b>Applications</b><br><ul><li>Motorcycles and scooters</li><li>All-terrain vehicles (ATV) and UTV</li><li>Karts and small recreational vehicles</li><li>Golf carts and light utility vehicles</li><li>Outboard combustion engines, light aircraft auxiliary power, UAVs</li></ul><br><b>Technical specifications</b><br><ul><li>Chemistry: LiFePO4 (Lithium Iron Phosphate)</li><li>Nominal voltage: 13.2 V (marketed as 12V starter batteries)</li><li>Available capacities: 2.5 Ah, 5.0 Ah, 7.5 Ah, 10 Ah</li><li>Max charge voltage: 14.4–14.6 V</li><li>Min discharge voltage: 8 V</li><li>Max charge current: 5 A / 10 A / 15 A / 20 A depending on model</li><li>Max starter (cranking) current: 120 A / 240 A / 360 A / 480 A depending on model</li><li>Dimensions and weights as listed per model</li><li>Equivalent lead-acid rating (PbEq): 7 Ah / 10 Ah / 20 Ah / 35 Ah</li><li>Operating temperature: typically -30℃ to 70℃</li><li>Self-discharge: approx. 1.5% per month</li><li>Case: ABS hard case</li></ul>
