It fits the DMC-TZ41, DMC-ZS30, DMC-TS5, DMC-TZ40, and over 30 additional Lumix models sharing the same battery bay and BMS handshake. Voltage and physical dimensions match OEM spec exactly — 41.50 × 34.00 × 8.50mm.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eDMW-BCM13 platform compatibility:\u003c\/strong\u003e\n    These Lumix models share the same 3.7V rail, locking tab position, and BMS communication protocol. A single cell design covers the full range because Panasonic standardised the connector and charge termination logic across this compact series.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through the DMC-TZ41 body and a DMW-BTC10 charger. The BMS accepted the cell on first insertion, reported charge state correctly, and terminated charge cleanly at full voltage without thermal flags.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-cycle calibration on the Lumix body:\u003c\/strong\u003e\n    Run the first full charge cycle through the camera body itself, not a third-party charger. The Lumix BMS maps the discharge curve to the battery-remaining indicator during that first in-body charge — skipping it can cause the percentage display to read incorrectly for several cycles.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eFlash recycling lag on a new DMW-BCM13 cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe built-in flash draws a sharp recharge current spike after each firing. At mid-discharge, the cell's internal resistance rises enough to slow the capacitor recharge — you'll see the flash-ready indicator take longer than usual between shots. This is normal cell behaviour, not a fault with the replacement. If recycling lag appears early in a charge cycle, check that the battery contacts on the camera body are clean and making full contact.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBattery percentage jumping around after fitting a replacement cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Lumix battery-remaining display uses voltage thresholds calibrated to the OEM cell's discharge curve. A new third-party cell with a slightly different curve can cause the percentage to jump — for example, dropping from 80% to 50% without warning. This is a calibration mismatch, not a faulty battery. Run two full charge-discharge cycles through the camera body and the indicator will stabilise as the BMS learns the new cell's actual discharge profile.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43333760909402,"sku":"BWCS-BCM13MC-1","price":22.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43333760942170,"sku":"BWCS-BCM13MC-2","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43333760974938,"sku":"BWCS-BCM13MC-3","price":27.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-BCM13MC_1.webp?v=1778213067","url":"https:\/\/batteryweb.com\/products\/panasonic-lumix-dmc-tz41-replacement-battery-37v-950mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
