It matches the original voltage rail and connector used in the Mack Link platform. Swap it in when the original cell no longer holds a charge or triggers persistent low-battery warnings during patient examinations.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eMack Link platform fit:\u003c\/strong\u003e\n    The Mack Link uses a single-cell 3.7V Li-ion pack with a BMS that handshakes with the device firmware at startup. This replacement uses the same cell chemistry and connector pinout, so the BMS negotiation completes without error flags.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through charge, full-load discharge, and BMS verification. The protection circuit held voltage within spec under continuous draw, and the charge IC accepted a full charge cycle without triggering fault codes.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-swap startup protocol:\u003c\/strong\u003e\n    After installing this battery, let the Mack Link complete its full power-on self-test without interruption. The BMS runs a chemistry verification at boot — cutting power mid-sequence creates a false battery fault that sticks until the next clean reboot cycle.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eDevice not completing boot sequence on a new Mack Link battery\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Mack Link BMS runs a verification pass during the boot sequence to confirm cell chemistry and state-of-charge. A new cell arriving partially discharged from storage may read below the firmware's minimum boot threshold, which halts startup before the device reaches the home screen. This is a BMS gate, not a faulty battery. Charge the replacement fully before the first boot — confirmed full charge reads 4.2V at the cell terminals — then power on and allow the self-test to finish uninterrupted.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCharge indicator not reaching 100% on the first charge cycle\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eOn the first charge, the Mack Link's charge IC applies a conservative current limit to an unrecognised cell, which causes the indicator to stall below 100% or take significantly longer than expected. This is normal behaviour — the IC is profiling the new cell before committing to a full-rate charge. Complete one full charge-discharge cycle, and the charge IC recalibrates its upper limit. After that first cycle, the indicator will reach 100% at the standard rate.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381399486554,"sku":"BWCS-GML170MD-1","price":45.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381399519322,"sku":"BWCS-GML170MD-2","price":53.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381399552090,"sku":"BWCS-GML170MD-3","price":59.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-GML170MD-1.webp?v=1778900536","url":"https:\/\/batteryweb.com\/products\/ge-mack-link-replacement-battery-37v-2600mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
