It matches the OEM footprint at 68.45 × 48.00 × 4.20mm and connects directly to the existing charge IC and fuel gauge circuit. Voltage and capacity figures come from the product data, not estimated from third-party listings.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003e5213 and 5216d compatibility:\u003c\/strong\u003e\n    Both models share the same battery bay dimensions, connector pinout, and BMS handshake logic. Either OEM part number — CPLD-111 or CPLD-106 — will seat and communicate correctly with the charge controller on both devices.\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 under modem-active load conditions. The BMS held cutoff at the correct lower threshold and the charge IC accepted the full 1500mAh without tripping a fault flag.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration on first use:\u003c\/strong\u003e\n    On first use after installation, disable fast charging and run one complete discharge-charge cycle to the charger's natural cutoff. This lets the coulomb counter recalibrate its discharge curve against the new cell before high-current charging pushes current into an uncalibrated state.\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 Coolpad 5213 after a cell swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe Coolpad 5213's fuel gauge IC retains the discharge curve of the old, degraded cell after a swap. When the modem transmits or the screen brightness spikes, current draw pulls the new cell's terminal voltage below what the fuel gauge expects at that state-of-charge, triggering an emergency shutdown. The phone reads 20–30% but the fuel gauge IC has already hit its voltage floor under load. One full uninterrupted discharge cycle — down to automatic shutdown, then charged to 100% without interruption — forces the coulomb counter to remap the curve against the replacement cell.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003ePhone will not power on after the replacement battery sat in storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-ion cells self-discharge at roughly 2–3% per month in storage. If this cell dropped below 2.5V per cell before installation, the BMS enters a lockout state and blocks normal charging to prevent thermal runaway on an over-discharged cell. Plugging into a standard charger shows nothing — no charging indicator, no boot. Connect to a 5V USB charger and leave it undisturbed for 20–30 minutes; at that point the BMS trickle-charges the cell back above the 2.5V recovery threshold and normal charging resumes. If the phone still does not respond after 45 minutes, check that the battery connector is fully seated on the motherboard.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43404218826842,"sku":"BWCS-CPD106SL-1","price":23.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43404218859610,"sku":"BWCS-CPD106SL-2","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43404218892378,"sku":"BWCS-CPD106SL-3","price":28.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-CPD106SL-1.webp?v=1779369390","url":"https:\/\/batteryweb.com\/products\/coolpad-5213-replacement-battery-37v-1500mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
