It slots directly into the battery bay on either body and connects to the same BMS interface as the original cell. Capacity figures come from the product data — 2.96Wh at rated voltage.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eWG-M2 and WG-M1 platform:\u003c\/strong\u003e\n    Both cameras share the same battery bay geometry, connector pinout, and BMS communication protocol. One cell fits both bodies without modification or adapter.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through charge and discharge cycles on a camera-class BMS test rig. The protection circuit responded correctly to cutoff thresholds, and the cell held voltage within expected tolerance across the discharge curve.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eCold-weather shooting tip:\u003c\/strong\u003e\n    The WG-M2 is built for outdoor use, including cold conditions — but Li-ion cells lose usable capacity below 5°C. Keep a spare cell in an inside jacket pocket between swaps so it enters the camera closer to ambient body temperature rather than ambient air temperature.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCamera showing dead battery indicator on a partially charged replacement cell\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe WG-M2's battery indicator maps voltage thresholds to a discharge curve calibrated to the OEM cell. A new third-party cell can present a slightly different resting voltage at the same state of charge, which the camera misreads as critically low. This is a BMS calibration issue, not a faulty cell. Run one full charge cycle through the OEM charger or via the camera body's USB charging port, then discharge normally — the indicator typically stabilises after one complete cycle.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBattery percentage jumping erratically on the WG-M2 display\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eErratic percentage readings happen when the camera's voltage-to-percentage mapping doesn't align with the new cell's discharge curve shape. The WG-M2 samples terminal voltage at intervals and converts it to a percentage — if the cell's mid-discharge voltage plateau sits slightly higher or lower than the OEM reference, the display jumps. This is a display calibration artefact, not a capacity problem. Complete two full charge-discharge cycles and the indicator will track more accurately as the camera logs the new cell's behaviour.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43333872779354,"sku":"BWCS-NP50FU-1","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43333872812122,"sku":"BWCS-NP50FU-2","price":29.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43333872844890,"sku":"BWCS-NP50FU-3","price":31.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-NP50FU-1.webp?v=1777949432","url":"https:\/\/batteryweb.com\/products\/ricoh-wg-m2-replacement-battery-37v-800mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
