It powers the camera's imaging sensor, drive motor, and flash system. Voltage and cell format match the original specification exactly.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003e8-308 and 8-406 series compatibility:\u003c\/strong\u003e\n    These models share a common 6V power rail, identical battery bay dimensions, and the same connector orientation. The BMS handshake across this series reads cell voltage rather than an encoded chip signal, so a correctly spec'd Ni-MH replacement is accepted without an authentication conflict.\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 the 8-308 platform. The BMS accepted the cell on the first charge, reported a stable voltage curve throughout discharge, and the flash capacitor recycled consistently across the full cycle.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFlash system charge tip:\u003c\/strong\u003e\n    Ni-MH cells at rest self-discharge faster than Li-ion. If this camera sits unused for more than a few weeks, the flash will take noticeably longer to recycle on the first shots — charge the battery fully before any shoot session, not just before storage.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eFlash output dropping mid-shoot on a new Ni-MH cell\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eNi-MH cells deliver voltage on a flat discharge curve that drops sharply near the end of capacity. The 8-308's flash capacitor draws a concentrated burst of current to recharge between shots. As cell voltage begins that final drop, the capacitor takes longer to reach full charge — and if you shoot before it does, flash output is reduced. This isn't a fault with the cell; it's the normal end-of-discharge behaviour of Ni-MH chemistry. Watch for flash recycle time increasing as your signal to charge — don't wait for the camera to report low battery.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBattery percentage jumping erratically on the display after fitting a new cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Minolta 8-series battery indicator maps display segments to fixed voltage thresholds calibrated against the original cell's discharge curve. A new Ni-MH replacement — especially one that hasn't been through a full charge cycle — sits at a slightly different resting voltage than the camera expects at each segment boundary. This causes the indicator to skip segments or read higher than actual on first use. Run one complete charge-to-discharge cycle through the camera body or OEM charger. After that cycle, the indicator will track the new cell's curve accurately and the jumping will stop.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43333890146394,"sku":"BWCS-NP55-1","price":35.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 2 Year","offer_id":43333890179162,"sku":"BWCS-NP55-2","price":41.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 3 Year","offer_id":43333890211930,"sku":"BWCS-NP55-3","price":45.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-NP55-1.webp?v=1778213590","url":"https:\/\/batteryweb.com\/products\/minolta-8-308-replacement-battery-6v-2100mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
