It slots directly into the KD-300Z battery compartment and powers the image sensor, LCD, and processing circuits. Voltage and connector match the original cell exactly.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eRevio KD-300Z compatibility:\u003c\/strong\u003e\n    The KD-300Z uses the DR-LB1 form factor — a slim 68.20 × 24.85 × 6.50mm cell with a fixed voltage rail at 3.7V. The camera's power circuit expects this profile. Any deviation in dimension or nominal voltage causes rejection at the battery door or during BMS initialisation.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through the KD-300Z charge and discharge sequence. The BMS accepted the cell without error flags, and the protection circuit triggered correctly at the low-voltage cutoff threshold — no premature shutdown during continuous image playback or LCD-on standby draw.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-charge protocol for the KD-300Z:\u003c\/strong\u003e\n    Run the first charge cycle through the camera body or OEM charger rather than a generic third-party adapter. The KD-300Z BMS maps its battery-remaining display against a charge curve calibrated on the first cycle — skipping this step causes the indicator to read inaccurately for several subsequent cycles.\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 KD-300Z display\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe KD-300Z maps its battery-remaining indicator against fixed voltage thresholds set for the original DR-LB1 discharge curve. A new replacement cell — even a correctly specced one — can discharge at a slightly different rate across its first few cycles. The camera reads the voltage at those thresholds and translates it into percentage steps, so the display jumps rather than stepping down smoothly. Run two or three full charge-discharge cycles and the indicator stabilises. If jumping persists after three cycles, check that charge voltage at the terminal is reaching 4.2V.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eKD-300Z showing dead-battery indicator on a partially charged replacement cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the camera body has not completed an initial handshake charge cycle with the new cell. The KD-300Z's power management circuit expects the cell to have been charged from within the camera or OEM charger at least once before it trusts the reported state-of-charge. Insert the battery and charge fully via the camera body before shooting. After one complete in-camera charge cycle, the dead-battery flag clears and the indicator reports accurately. Target a full charge termination at 4.2V before the first use.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43333866586202,"sku":"BWCS-BP800-1","price":22.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 2 Year","offer_id":43333866618970,"sku":"BWCS-BP800-2","price":25.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 3 Year","offer_id":43333866651738,"sku":"BWCS-BP800-3","price":27.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-BP800-1.webp?v=1778213288","url":"https:\/\/batteryweb.com\/products\/konica-revio-kd-300z-replacement-battery-37v-1000mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
