It replaces part number TBT5957 when the original cell can no longer hold a usable charge. Dimensions are 72.00 x 57.06 x 4.36mm — measure your existing cell before ordering if you are unsure.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eHighscreen Spider fit:\u003c\/strong\u003e\n    The Spider uses a direct-connect flat cell with a three-pin flex connector carrying voltage, ground, and a thermistor line. The BMS on this replacement matches that pin layout and the charge voltage ceiling the Spider's PMIC expects at 4.35V.\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 Spider platform. The BMS accepted the charge handshake without tripping the PMIC's overcurrent threshold, and the protection circuit cut correctly at the low-voltage floor.\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 full discharge-charge cycle at standard rate. This lets the fuel gauge IC map its coulomb counter against the new cell's discharge curve before any 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\"\u003eWhy the Highscreen Spider reports wrong battery percentage after a cell swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Spider's fuel gauge IC stores a learned discharge curve from the original cell. When you fit a new cell, that stored curve no longer matches the actual voltage-to-capacity relationship of the replacement. The gauge reads voltage and maps it to a percentage using stale data, so the number on screen drifts. One full discharge to auto-off followed by a complete charge cycle rewrites the reference curve and brings the percentage display back in line.\u003c\/p\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\"\u003eThis happens when the cell voltage drops sharply under modem or display load — a voltage cliff the fuel gauge did not predict. The Spider's PMIC shuts the device down to protect the cell before the displayed percentage reaches zero. It is not a faulty battery; it means the coulomb counter has not yet calibrated the new cell's internal resistance profile. Run two full discharge-charge cycles and the shutdowns typically stop. If they persist past three cycles, check that the flex connector is fully seated — a high-resistance contact causes the same voltage sag symptom.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43392064880730,"sku":"BWCS-KTT310SL-1","price":23.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43392064913498,"sku":"BWCS-KTT310SL-2","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43392064946266,"sku":"BWCS-KTT310SL-3","price":29.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-KTT310SL-1.webp?v=1779143561","url":"https:\/\/batteryweb.com\/products\/highscreen-spider-replacement-battery-38v-2200mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
