It slots into the VMA80 body and restores full shooting capability when the original cell has degraded. Capacity is rated at 25.2Wh.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eVMA80 platform fit:\u003c\/strong\u003e\n    The VMA80 uses a 6V Ni-MH cell with a specific form factor — 88.95 x 47.55 x 36.50mm. This replacement matches that footprint and voltage rail so the battery door closes correctly and the camera's power circuit sees the expected input.\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 under camera-representative loads — including flash capacitor recharge draws. The BMS held charge delivery stable and did not trip on the current spikes that occur between shots.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst charge cycle on the VMA80:\u003c\/strong\u003e\n    Run the first full charge through the camera body or OEM charger before heavy shooting. Some NEC camera BMS implementations calibrate the battery-remaining display during that first complete charge cycle — skipping it can cause the indicator to read inaccurately from the start.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBattery percentage jumping erratically on the VMA80 display\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe VMA80's battery indicator maps voltage thresholds to percentage steps based on the discharge curve of the original NEC cell. A fresh replacement Ni-MH cell has a slightly flatter discharge curve than an aged original, which means the camera's voltage-to-percentage translation can misread the cell state. This causes the indicator to jump — sometimes from full to half in a few shots, then stall. One full charge-discharge cycle through the camera body typically allows the BMS to recalibrate. After that cycle, the display should track the actual cell state correctly.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eFlash not fully recycling between shots on new cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eFlash recycling on the VMA80 draws a sharp current spike to recharge the capacitor after each shot. If the replacement cell is new and has not completed a break-in cycle, internal resistance is slightly elevated — enough to slow capacitor recharge under rapid shooting. The symptom is a longer-than-normal wait between flash-ready confirmations, or a dimmer flash output on quick successive shots. Run two to three full charge-discharge cycles and internal resistance drops to operating spec. After break-in, recycling time returns to normal.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43333899157594,"sku":"BWCS-NP66-1","price":50.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43333899190362,"sku":"BWCS-NP66-2","price":58.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43333899223130,"sku":"BWCS-NP66-3","price":64.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-NP66_1.webp?v=1778213590","url":"https:\/\/batteryweb.com\/products\/nec-vma80-replacement-battery-6v-4200mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
