It matches OEM voltage and physical dimensions exactly — 53.20 × 35.30 × 7.10mm — so it seats flush in the battery compartment. Capacity listed here is from product data: 1050mAh (3.89Wh).\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eMega Image 34 \/ 37 \/ 47 platform:\u003c\/strong\u003e\n    These three compact models share the same battery bay dimensions, voltage rail, and contact pin layout, which is why a single cell covers all three. The BMS expects 3.7V nominal — any meaningful deviation and the camera body flags a fault before the shutter unlocks.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through charge and discharge on a compatible camera body. The BMS accepted the cell without fault flags, held charge cutoff at 4.2V, and low-voltage protection tripped cleanly before the cell dropped below safe floor voltage.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-install charge cycle:\u003c\/strong\u003e\n    Insert this battery and run one full charge cycle through the camera body or OEM charger before shooting. Some compact camera BMS controllers need that first in-body charge cycle to calibrate the battery-remaining indicator correctly — skipping it often produces erratic percentage readings during early use.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eFlash not fully recycling between shots on a new Mega Image battery\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Mega Image 37's built-in flash draws a sharp current spike to recharge its capacitor between shots. As a Li-ion cell ages — or if a new cell is cold — internal resistance rises enough to slow that capacitor recharge. The result is a longer-than-normal recycle delay or a visibly weaker flash output on consecutive frames. If you see this on a fresh replacement cell, warm the camera to room temperature first; cold cells above 15°C internal resistance can behave like an end-of-life cell until the chemistry warms up.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCamera showing dead battery indicator on a partially charged replacement cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Mega Image series maps battery percentage against a fixed voltage-threshold curve tuned to the original cell's discharge profile. A new third-party cell with a slightly different discharge curve can read as depleted even when it holds 3.6V or above. The fix is straightforward: charge the replacement fully in the camera body, then let it discharge through normal use once. After that full cycle, the indicator typically tracks accurately against the new cell's actual discharge curve.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43333913804890,"sku":"BWCS-NP60FU-1","price":22.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43333913837658,"sku":"BWCS-NP60FU-2","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43333913870426,"sku":"BWCS-NP60FU-3","price":27.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-NP60FU-1.webp?v=1778213591","url":"https:\/\/batteryweb.com\/products\/yakumo-mega-image-37-replacement-battery-37v-1050mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
