It fits the Pentax Optio X90 and MX-1 compact cameras. The battery slots into the same compartment as the original and draws power through the same contact layout.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eOptio X90 and MX-1 compatibility:\u003c\/strong\u003e\n    Both cameras run off the same D-LI106 footprint — shared voltage rail at 3.7V, identical connector orientation, and the same BMS handshake protocol. One cell covers both bodies without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through the Optio X90 body and tracked BMS behaviour across charge and discharge. The protection circuit tripped correctly at low-voltage cutoff and accepted full recharge without fault codes.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-install charge cycle:\u003c\/strong\u003e\n    Insert this cell into the camera body or OEM charger and run one complete charge before heavy shooting. Some Pentax BMS builds only begin accurate battery-remaining display after a full charge cycle is completed inside the camera body itself.\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 on the Optio X90 display after fitting a new cell\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe Optio X90 maps its battery indicator to a fixed voltage-threshold table calibrated against the original cell's discharge curve. A new replacement cell — even at the correct capacity — may discharge along a slightly different voltage slope. The camera reads those voltage points and maps them to the wrong percentage segments, producing visible jumps. Running one full charge-discharge cycle inside the camera body allows the BMS to resample the curve and stabilise the indicator. After that cycle, the display should track consistently down to the low-battery cutoff near 3.0V.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eFlash not fully recycling between shots on a new D-LI106 cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe built-in flash on the Optio X90 pulls a short high-current spike to recharge its capacitor between frames. If the cell's internal resistance is slightly elevated — common in a new cell that hasn't been cycled yet — that current draw causes a momentary voltage sag the BMS interprets as marginal charge. The camera then throttles flash recharge to protect the circuit, extending recycle time. Cycle the battery fully once and retest; internal resistance drops after the first complete cycle and recycle time returns to normal.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43333811634266,"sku":"BWCS-DLI106MC-1","price":22.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43333811667034,"sku":"BWCS-DLI106MC-2","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43333811699802,"sku":"BWCS-DLI106MC-3","price":27.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-DLI106MC_1.webp?v=1778213246","url":"https:\/\/batteryweb.com\/products\/pentax-optio-x90-replacement-battery-37v-1000mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
