The slim 63 × 42 × 4.5mm form factor matches the original cell's footprint exactly. Voltage and capacity are matched to what Panasonic specified for this camera line.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eHX-A series compatibility:\u003c\/strong\u003e\n    The HX-A100, HX-A1M, HX-A100-H, and HX-A500 all run on the same 3.7V rail with the same VSB0526 connector footprint and BMS handshake. One cell covers the full wearable range without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through the HX-A100 body and monitored BMS communication. The protection circuit responded correctly to charge termination and low-voltage cutoff — no false trips under normal camera load.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst charge cycle on camera body:\u003c\/strong\u003e\n    Charge this cell in the HX-A100 body via the OEM charger before your first recording session. Some Panasonic wearable BMS systems need one full in-body charge cycle to correctly map the battery-remaining percentage display to the new cell's discharge curve.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the HX-A100 runs warm during sustained video recording\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe HX-A100 stacks image sensor readout, video encoding, image stabilisation, and wireless output into a body smaller than most phones. That combined draw pulls more continuous current from the cell than a still-photo session ever would. Li-Polymer cells generate heat as internal resistance rises under sustained load — especially in a sealed housing with no active airflow. Keeping the camera out of direct sunlight during long clips reduces heat buildup and slows voltage sag at the cell level.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBattery percentage jumping erratically on the HX-A100 display\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe HX-A100's fuel gauge maps voltage thresholds to percentage steps that were calibrated against the original cell's discharge curve. A new Li-Polymer cell has a slightly flatter discharge curve early in its life, so the camera's indicator can read 80% one moment and drop to 50% after a short clip. This is a gauge calibration issue, not a cell fault. Run two or three full charge-and-discharge cycles in the camera body and the BMS will re-map the thresholds — the readout will stabilise to within a few percentage points.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43333613617242,"sku":"BWCS-PNA100MC-1","price":28.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43333613650010,"sku":"BWCS-PNA100MC-2","price":32.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43333613682778,"sku":"BWCS-PNA100MC-3","price":35.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-PNA100MC-1.webp?v=1778212994","url":"https:\/\/batteryweb.com\/products\/panasonic-hx-a100-replacement-battery-37v-1500mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
