It replaces OEM part number C533457105T directly. Swap it in when the original cell no longer holds a charge or causes unexpected shutdowns.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eDIVA and T350 platform compatibility:\u003c\/strong\u003e\n    These models share the same battery bay dimensions (53.00 × 33.90 × 5.70mm), voltage rail, and connector pinout. One cell covers the whole 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 the DIVA platform and confirmed the BMS handshake completes correctly — no false low-battery flags and no premature charge termination on the first cycle.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration on first use:\u003c\/strong\u003e\n    On the first charge after installation, disable fast charging and run the battery from 100% down to below 10% before plugging back in. This gives the fuel gauge IC one clean pass against the new cell's discharge curve before fast-charge current is applied to an uncalibrated cell.\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 replacement cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe DIVA's fuel gauge IC stores a charge curve calibrated to the original cell. A fresh replacement cell has a slightly different internal impedance profile, so the IC underestimates remaining capacity and triggers a low-voltage cutoff too early. This looks like a sudden shutdown while the percentage still reads 20–30%. One full discharge-charge cycle — without interruption — forces the coulomb counter to relearn the new curve. After that cycle, shutdowns at falsely high percentages stop.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003ePhone warm near the battery during the first charge\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eA new Li-ion cell arrives with higher internal impedance than a broken-in cell. During the first charge, the phone's charge IC pushes current into this higher-resistance cell, and the extra energy dissipates as heat near the battery compartment. This is expected on the first one or two cycles and fades as the cell's impedance settles. If the phone stays warm beyond the third full charge, check that the charging current has dropped by confirming the phone's charge mode indicator is showing standard charge, not a fast-charge session.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43404179308634,"sku":"BWCS-JTP127SL-1","price":23.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43404179341402,"sku":"BWCS-JTP127SL-2","price":27.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43404179374170,"sku":"BWCS-JTP127SL-3","price":29.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-JTP127SL-1.webp?v=1779369289","url":"https:\/\/batteryweb.com\/products\/blu-diva-replacement-battery-37v-1200mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
