It fits the Pantech Reveal C790 Aladdin, C530, C530 Slate, Link P7040, and six additional Pantech handsets sharing the same connector and voltage rail. Dimensions are 44.05 × 39.27 × 5.51mm — measure your bay before ordering if you're unsure of your exact variant.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eC530 and C790 platform compatibility:\u003c\/strong\u003e\n    These models share the same single-cell 3.7V Li-ion architecture, connector pinout, and BMS communication protocol. One cell fits across the lineup 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 charge and discharge on a C530 body. The BMS handshake initialised correctly on first insertion, charge IC accepted the cell without rejecting it, and protection circuits tripped at expected voltage thresholds.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration on first use:\u003c\/strong\u003e\n    On first install, run one full discharge down to auto-shutoff, then charge uninterrupted to 100% without pulling the phone off charge early. The Pantech fuel gauge IC reads coulomb data against a stored discharge curve — skipping this step causes the percentage display to drift against the new cell's actual capacity.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eSudden shutdown at 20–30% on the C790 and C530\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe C790 and C530 run a modem radio and display backlight simultaneously during calls or video — two high-draw loads that spike current demand instantly. A cell with any internal resistance above spec cannot sustain voltage under that combined load, and the BMS reads the resulting sag as a hard undervoltage condition. The phone cuts out even though the fuel gauge still shows charge remaining. Completing one full calibration cycle after install reduces this — the fuel gauge IC learns the actual voltage cliff of the new cell and adjusts its cutoff estimate accordingly.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003ePhone won't power on after the battery sat in storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-ion cells left uncharged for extended periods drop below 2.5V per cell, which triggers a BMS lockout to prevent unsafe charging into a depleted cell. The Pantech C530 and C790 will not boot from this state — the screen stays dark and the charge indicator may not respond. Connect the phone to a wall adapter, not a PC USB port, and leave it for 20–30 minutes before attempting to power on. Once voltage recovers above the BMS reinitialisation threshold — typically around 2.9V — the phone will begin a normal charge cycle.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43405073252442,"sku":"BWCS-PTC530SL-1","price":22.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43405073285210,"sku":"BWCS-PTC530SL-2","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43405073317978,"sku":"BWCS-PTC530SL-3","price":27.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-PTC530SL-1.webp?v=1779369934","url":"https:\/\/batteryweb.com\/products\/pantech-reveal-c790-aladdin-replacement-battery-37v-800mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
