It matches the OEM part numbers LG144 and 510001-144. The Renasys Go draws consistent power during wound therapy cycles, and a depleted or degraded original battery will interrupt treatment.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eRenasys Go platform fit:\u003c\/strong\u003e\n    The Renasys Go uses a 14.4V battery rail with a BMS handshake that authenticates cell chemistry at startup. This replacement uses the same Li-ion chemistry and connector configuration so the device controller accepts it through its self-test sequence without flagging an incompatible source alarm.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through the Renasys Go power-on self-test and full charge cycle on the bench. The BMS initialised correctly, accepted the charge without fault codes, and held voltage within the expected range across a full discharge profile matching typical therapy load.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-installation self-test protocol:\u003c\/strong\u003e\n    After fitting this battery, let the Renasys Go complete its full power-on self-test cycle without interrupting it. The device runs BMS verification at startup, and cutting power mid-sequence can register a false battery fault that persists until the next clean reboot.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the Renasys Go alarms low battery immediately after a confirmed full charge\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Renasys Go BMS applies a charge-acceptance threshold calibrated to the OEM cell's internal resistance profile. A new replacement cell has a slightly different resistance signature on its first cycle, which can cause the BMS to report capacity below the alarm threshold even when the cell is physically full. This is a BMS learning behaviour, not a fault with the battery. Run one complete charge-discharge cycle on the device and the BMS recalibrates its threshold to the new cell's actual profile.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eRenasys Go not powering on after battery has been in storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-ion cells self-discharge over time, and if a replacement battery has sat in storage, its resting voltage may drop below the Renasys Go BMS recovery threshold — typically around 10V on a 14.4V pack. Below that threshold, the BMS enters deep-discharge protection and blocks startup entirely. Place the battery on a compatible 14.4V Li-ion charger and allow a trickle charge to bring the cell above the recovery floor before reinserting it into the device. Once the pack reads above 11V, normal charging resumes.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381392932954,"sku":"BWCS-SNR144MD-1","price":63.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381392965722,"sku":"BWCS-SNR144MD-2","price":75.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381392998490,"sku":"BWCS-SNR144MD-3","price":83.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-SNR144MD-1.webp?v=1778900565","url":"https:\/\/batteryweb.com\/products\/smith-nephew-renasys-go-replacement-battery-144v-2600mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
