It matches OEM part numbers CAB32E0000C1, CAB32E0002C1, TLiB32E, CAB32E0000C2, and TLiB5AF. Swap it in when the original cell no longer holds a usable charge through a normal day of calls, messages, and basic apps.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eOT-997 and OT-997D compatibility:\u003c\/strong\u003e\n    Both handsets run the same 3.7V single-cell architecture with the same connector pinout and BMS handshake requirements. This cell satisfies both variants without any modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through full charge and discharge on the OT-997 platform. The BMS accepted the cell on first insertion and the charge IC reached termination voltage cleanly without false cutoff events.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration on first cycle:\u003c\/strong\u003e\n    After installing this cell, run one complete discharge down to auto-shutdown and then charge uninterrupted to 100% before normal use. The OT-997 fuel gauge IC was calibrated to your old degraded cell — it needs one full cycle against the new cell's discharge curve to report accurate percentages.\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 OT-997 after a cell swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe OT-997's fuel gauge IC holds a coulomb-counter model built from the old cell's degraded discharge curve. A fresh 1650mAh cell has a steeper voltage cliff in the low-charge region than the worn cell the phone learned from. When the modem fires up for a call or the screen brightness spikes, current draw pulls the cell voltage below the BMS cutoff threshold — even though the displayed percentage still reads 20% or higher. One full discharge-to-shutdown and uninterrupted recharge resets the counter model against the actual cell. After that cycle, the reported percentage and the real state of charge align.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eOT-997 not powering on after the replacement cell sat in storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-ion cells self-discharge during storage. If this battery shipped or sat on a shelf for several months, cell voltage may have dropped below 2.5V — the threshold where the BMS locks out to prevent damage. The phone will show nothing when you press the power button. Connect the handset to a wall charger rather than a USB port on a PC, since the charge IC needs a stable 5V source to push the trickle current required to recover a locked-out cell. Leave it on charge undisturbed for 20–30 minutes before attempting to power on; the BMS will release its lockout once the cell recovers to approximately 3.0V.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43404337905754,"sku":"BWCS-OT997SL-1","price":23.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43404337938522,"sku":"BWCS-OT997SL-2","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43404337971290,"sku":"BWCS-OT997SL-3","price":29.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-OT997SL-1.webp?v=1778773940","url":"https:\/\/batteryweb.com\/products\/alcatel-ot-997-replacement-battery-37v-1650mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
