It slots into cameras where the original Ni-MH pack has lost the ability to hold a working charge. Capacity is rated at 12.6Wh.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eKyocera 8KX-1 series compatibility:\u003c\/strong\u003e\n    These camera models share a common 6V Ni-MH pack format with matching connector pinout and physical dimensions of 88.95 x 47.55 x 20.73mm. The BMS in each body reads cell voltage at insertion — the same nominal 6V rail satisfies the check across the full compatibility list.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through full charge and discharge runs on camera-class draw loads. The BMS accepted the cell without faulting, and voltage held consistently above the low-battery cutoff threshold through the discharge curve.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-charge protocol for Ni-MH camera cells:\u003c\/strong\u003e\n    Charge this battery fully inside the OEM charger or camera body before your first shoot. Kyocera camera bodies map the battery-remaining indicator against a charge curve — skipping this step causes the display to show incorrect levels until the cell has completed one full cycle from within the system.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the Kyocera 8KX-1 shows a dead battery indicator on a partially charged replacement cell\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eKyocera camera bodies track remaining charge by mapping voltage readings to a pre-set discharge curve stored in firmware. A new Ni-MH replacement cell has a slightly different discharge profile compared to the aged original — the body reads an unfamiliar voltage slope and flags it as depleted. This is not a fault with the battery. Running one complete charge cycle inside the camera body or OEM charger re-anchors the indicator to the new cell's actual curve. After that cycle, the remaining-battery display behaves correctly.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBattery percentage jumping erratically on the Kyocera camera display\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNi-MH cells have a flatter discharge curve than Li-ion, which makes voltage-based fuel gauging less precise — especially mid-charge when the curve plateaus. If the indicator jumps between readings during a shoot, the camera body is sampling at a flat region of the curve and losing reference. This is more pronounced in cold conditions, where Ni-MH terminal voltage dips temporarily under load. Charge the battery fully to 6V nominal before shooting, and let the body re-sample after the first full cycle.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43333892866138,"sku":"BWCS-NP55-1","price":35.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 2 Year","offer_id":43333892898906,"sku":"BWCS-NP55-2","price":41.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 3 Year","offer_id":43333892931674,"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\/kyocera-8kx-1-replacement-battery-6v-2100mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
