It replaces OEM part number L02442001. Fits model references CQ720A and the eStation Zeen series directly.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eeStation Zeen and C510 platform fit:\u003c\/strong\u003e\n    Both the Zeen tablet and the C510 all-in-one share the same battery bay dimensions and connector pinout. The BMS handshake voltage thresholds are identical across CQ720A variants, so one cell covers the full model range listed.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through charge and discharge cycles on the eStation Zeen platform. The BMS accepted charge initiation without fault flags, held cutoff at the correct low-voltage threshold, and passed full capacity through the fuel gauge without tripping protection.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration after swap:\u003c\/strong\u003e\n    After fitting this battery, run the tablet down to automatic shutoff, then charge uninterrupted to 100% before use. The eStation's fuel gauge IC calibrates against the old cell profile — one full cycle resets it to the new cell and eliminates inaccurate percentage readings from the start.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eeStation Zeen shutting down at 15–25% remaining\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe eStation Zeen drives a backlit display and active WiFi simultaneously, which creates a combined load spike that the fuel gauge IC misreads as a voltage cliff. When the stored cell profile is stale — common after a battery swap — the IC triggers shutdown early rather than accurately tracking remaining charge. This is a calibration issue, not a cell defect. Run one full discharge-to-shutoff cycle followed by an uninterrupted charge to 100%, and the early-shutdown behaviour clears.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eFast charging unavailable on the eStation Zeen after a battery replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe eStation Zeen's charge IC negotiates charge rate during the first accepted cycle after a new cell is installed. Until that cycle completes, the system defaults to standard charge rate as a protection measure. This is not a fault with the replacement cell. Charge the tablet fully once without interruption — after that initial accepted cycle, the charge IC re-establishes the correct rate profile for subsequent sessions.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43425941880922,"sku":"BWCS-HCQ720SL-1","price":42.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43425941913690,"sku":"BWCS-HCQ720SL-2","price":49.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43425941946458,"sku":"BWCS-HCQ720SL-3","price":54.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-HCQ720SL-1.webp?v=1779930008","url":"https:\/\/batteryweb.com\/products\/hp-estation-zeen-replacement-battery-37v-5000mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
