It replaces OEM part numbers LB13H040 and HYLB-1370. The cell pack matches the original voltage rail and connector to restore normal device operation.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eG3H and G3HI30028-1 compatibility:\u003c\/strong\u003e\n    Both models run the same 11.1V three-cell Li-ion architecture with a shared BMS handshake protocol and identical connector pinout, which is why one pack covers both. Swapping between these two device variants carries no electrical risk.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through charge, full load, and BMS cutoff verification. The protection circuit tripped correctly at low-voltage threshold and recovered cleanly on reconnect. Charge acceptance was consistent across the first three cycles.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-installation self-test protocol:\u003c\/strong\u003e\n    After installation, allow the device to complete its power-on self-test cycle without interruption. The G3H runs BMS verification at startup, and cutting power during this sequence causes a false battery fault that persists until the next full reboot.\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 after battery swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe G3H runs a BMS learn cycle during its first few power-on sequences after a new cell is installed. If the device halts mid-boot, the BMS has not yet confirmed the new cell's state-of-charge profile against its internal thresholds. This is not a defective battery — it is the device's firmware protecting against unverified power sources in a clinical context. Complete one full charge-discharge cycle before placing the unit back into clinical use.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCharge indicator stalls below 100% on first charge\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eOn a fresh cell, the G3H charge IC applies a conservative current limit until it maps the new pack's internal resistance. This causes the charge indicator to plateau — typically between 85% and 95% — before the algorithm steps up to complete the cycle. The cell is not faulty and the capacity is not reduced. Leave the device on charge until the indicator advances; this self-corrects after the first complete charge cycle and does not repeat.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381439660122,"sku":"BWCS-GNL300MD-1","price":43.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381439692890,"sku":"BWCS-GNL300MD-2","price":51.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381439725658,"sku":"BWCS-GNL300MD-3","price":56.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-GNL300MD-1.webp?v=1778900838","url":"https:\/\/batteryweb.com\/products\/general-g3h-replacement-battery-111v-2600mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
