It also fits the GLB 200 18 Li-Ion and GRT 260 18 Li-ion. The OEM part numbers covered include 95510, 95513, 95514, 95515, 95517, 95519, and 490476.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003e18V Gude platform fit:\u003c\/strong\u003e\n    The GHS 520, GLB 200, and GRT 260 all share the same 18V battery rail, connector form factor, and BMS handshake protocol — one pack covers all three tools without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this pack through simulated hedge trimmer load cycles, including dual-blade inrush spikes at startup. The BMS held protection thresholds correctly and did not false-trip on normal cutting engagement.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eHalf-load break-in on first use:\u003c\/strong\u003e\n    Run the trimmer on lighter branch sections for the first two cycles before tackling dense overgrowth. This lets the BMS log the motor's inrush current profile and set overcurrent thresholds accurately — skipping this can cause nuisance trips on heavy first cuts.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBMS cutoff on motor-start inrush in the GHS 520\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eWhen the dual-blade motor engages, it pulls a short inrush spike well above the steady cutting current. A fresh pack with a conservative BMS — or one that has not yet profiled the load — can read that spike as an overcurrent fault and cut power instantly. The tool goes dead on the trigger pull, then resets after a few seconds. This is not a faulty battery; it is the BMS responding to an unfamiliar load signature. Two break-in cycles at half load teach the BMS where the normal spike ceiling sits.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCharger blinking red on a new pack that has been sitting in storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-ion packs self-discharge during storage. If the cell voltage drops below roughly 2.5V per cell, the Gude charger's acceptance circuit will not initiate a full charge cycle and signals a fault with a red blink. Some chargers include a recovery or wake mode — hold the pack in the charger for 5–10 minutes and check whether the light transitions to a steady charge state. If the charger never progresses, use a bench charger with a manual Li-ion recovery function set to 0.1C to bring cell voltage back above 3.0V per cell before returning to the standard charger.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43416034934874,"sku":"BWCS-GUD260PW-1","price":81.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43416034967642,"sku":"BWCS-GUD260PW-2","price":94.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43416035000410,"sku":"BWCS-GUD260PW-3","price":104.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-GUD260PW-1.webp?v=1779759609","url":"https:\/\/batteryweb.com\/products\/gude-ghs-520-18-li-ion-replacement-battery-18v-2000mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
