It fits the ZT3326AP, ZT3355US, ZT3019AP, ZT3300, and 248 additional models sharing the same connector and voltage rail. OEM part numbers covered include 337607-001, 337607-003, DG103A, and DL615A.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eZT3300 series compatibility:\u003c\/strong\u003e\n    These Pavilion models share a 14.8V four-cell Li-ion architecture with the same connector pinout and BMS handshake protocol. The BIOS identifies the cell pack by EEPROM data, so the replacement pack must match voltage and chemistry exactly — this one does.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through charge and discharge on ZT3300 series hardware. The BMS held steady across the full voltage window — no premature cutoff, no overcurrent trip during full CPU and display load.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-install recalibration on ZT3300:\u003c\/strong\u003e\n    After fitting this battery, run one full discharge until the laptop hibernates at cutoff, then charge uninterrupted to 100%. This resets the BIOS battery learn cycle and clears the inaccurate health warning that appears after a cell swap.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBIOS reporting poor battery health after replacing the ZT3300 cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe HP Pavilion ZT3300 BIOS reads health data from the battery's EEPROM — specifically the charge cycle count and design capacity stored on the old cell. A new pack arrives with zeroed or default EEPROM values that don't match what the BIOS expects. This triggers a \"Battery health is poor\" or similar warning even when the cell is brand new. One complete discharge-to-hibernate followed by a full uninterrupted charge gives the BIOS enough data to re-evaluate the pack correctly.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eLaptop shuts down at 20–30% charge shown on the ZT3300\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the fuel gauge IC hasn't calibrated against the new cell's actual voltage curve. The IC is still mapping capacity percentages against the old cell's degraded discharge profile, so it miscalculates where the voltage cliff sits. Under full CPU plus display load, actual cell voltage drops faster than the gauge predicts — the laptop hits the hardware cutoff before the displayed percentage reaches zero. Two to three full calibration cycles bring the fuel gauge IC into sync; shutdowns at false percentages stop once the IC has learned the new cell's curve down to the 3.0V per-cell cutoff.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43411620429914,"sku":"BWCS-CNX7000-1","price":81.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43411620462682,"sku":"BWCS-CNX7000-2","price":95.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43411620495450,"sku":"BWCS-CNX7000-3","price":106.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-CNX7000-1.webp?v=1779581402","url":"https:\/\/batteryweb.com\/products\/hp-pavilion-zt3326ap-pc997pa-replacement-battery-148v-4400mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
