It fits models listed as 5600 and TL-5600. Swap it in when the original battery no longer holds a charge long enough to be useful away from a power outlet.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eM5600 \/ TL-5600 fit:\u003c\/strong\u003e\n    Both model designations run the same 3.7V battery rail and use the TBL-45A1000 form factor — same connector, same BMS handshake, same physical footprint at 58.24 × 40.00 × 4.50mm.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this battery through charge and discharge on the M5600 platform. The BMS accepted the cell without error flags, and the device reported accurate charge state through the full cycle.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eVentilation during extended sessions:\u003c\/strong\u003e\n    Keep the M5600 on a hard, flat surface during long sessions — the cellular radio runs at full output power when connected devices are farther away, and trapping heat against soft surfaces accelerates cell stress.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eM5600 dropping connected devices mid-session on a new battery\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe M5600 runs two power-hungry systems simultaneously — the cellular modem and the Wi-Fi radio. When several devices are connected and the cellular signal is weak, both radios push to maximum output at the same time. That combined draw creates a brief voltage sag at the battery terminals. If the sag drops below the BMS cutoff threshold, the hotspot resets to protect the cell. A new battery with a fully charged cell handles the sag better than a degraded original, but the underlying cause is peak simultaneous draw — not a fault with the battery itself.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eM5600 not powering on after sitting unused in a drawer\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eLi-ion cells self-discharge over time — typically 1–2% per week at room temperature. Left unused for several months, the M5600 battery can fall below the minimum boot voltage the BMS requires to allow a startup sequence. The device will appear completely dead even when placed on charge. Connect it to the original charger and leave it for at least 30 minutes before attempting to power on — most BMS circuits begin a trickle-recovery charge once the cell reaches approximately 2.5V, after which normal charging resumes.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43377834950746,"sku":"BWCS-TTR560SL-1","price":23.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43377834983514,"sku":"BWCS-TTR560SL-2","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43377835016282,"sku":"BWCS-TTR560SL-3","price":28.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-TTR560SL-1.webp?v=1778773895","url":"https:\/\/batteryweb.com\/products\/tp-link-5600-replacement-battery-37v-1000mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
