It matches the OEM NP-900 form factor, voltage, and connector. Fits the EZ 4033 body directly — no adapters or modification needed.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eEZ 4033 battery slot compatibility:\u003c\/strong\u003e\n    The NP-900 format is shared across Kyocera's compact EZ-series cameras because they run the same 3.7V single-cell architecture. Same connector orientation, same BMS handshake voltage, same physical footprint at 43.70 × 31.30 × 7.00mm.\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 EZ 4033 platform. The BMS accepted the cell without error flags, and protection circuits tripped correctly at low-voltage cutoff — no runaway discharge on the bench.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-use charge cycle on the EZ 4033:\u003c\/strong\u003e\n    Run one full charge cycle through the camera body or OEM charger before shooting. The EZ 4033's battery-remaining indicator maps to the cell's discharge curve — skipping this step can cause the indicator to read inaccurately from the first shot.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eEZ 4033 showing a dead-battery indicator on a partially charged replacement cell\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe EZ 4033 estimates remaining charge by reading cell voltage against a stored discharge curve. A new replacement cell's curve doesn't always match that stored reference on the first install. The camera interprets the voltage offset as a low or dead cell and shuts down early. One full charge-discharge cycle through the camera body re-aligns the BMS reference points, and the indicator normalises from the next session onward.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBattery percentage jumping erratically on the EZ 4033 display\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the camera's voltage-threshold map doesn't match the discharge curve of the replacement cell. The indicator jumps because it's hitting thresholds out of sequence — 60% dropping to 20% with no warning, for example. It's a calibration issue, not a faulty cell. Discharge the battery fully until the camera shuts off, then charge it to 100% uninterrupted — the threshold map resets and the display stabilises at 4.2V full charge.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43333825232986,"sku":"BWCS-NP900-1","price":22.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43333825265754,"sku":"BWCS-NP900-2","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43333825298522,"sku":"BWCS-NP900-3","price":27.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-NP900-1.webp?v=1778213259","url":"https:\/\/batteryweb.com\/products\/kyocera-ez-4033-replacement-battery-37v-600mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
