The ST6 runs on a proprietary battery platform, and this unit matches that voltage rail and form factor exactly. Capacity is rated at 25.92Wh.\u003c\/p\u003e\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eST6 compatibility:\u003c\/strong\u003e The ST6 hedge trimmer draws from a fixed 7.2V rail with a specific connector and BMS pairing — this battery matches that configuration without modification.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e We ran full charge\/discharge cycles — the BMS held voltage under load across the cutting cycle and released cleanly at the low-voltage cutoff.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eFirst-cycle conditioning for Ni-MH:\u003c\/strong\u003e Run the battery through two or three full charge and discharge cycles before expecting full capacity — Ni-MH cells need this to reach rated output.\u003c\/li\u003e\n  \u003c\/ul\u003e\n  \u003chr class=\"bpw-desc-divider\"\u003e\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy Ni-MH suits a hedge trimmer like the ST6\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNi-MH cells tolerate the high-current bursts a hedge trimmer draws when blades hit thick stems. The chemistry is also more forgiving of partial charges than older Ni-Cd packs. At 3600mAh, this unit delivers more stored energy than the original factory rating on many ST6 variants. That headroom matters when cutting dense or mature hedgerow.\u003c\/p\u003e\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBattery not charging after storage — here is the cause and fix\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNi-MH cells that sit discharged for extended periods can drop below the threshold a charger will recognize, triggering a no-charge state. This is called voltage depression, not cell failure. Connect the battery and leave the charger running — many chargers will trickle charge below the detection threshold and recover the pack within a few hours. If the charger has a refresh or recovery mode, use it first.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43175825670234,"sku":"BWCS-GRA600PW-1","price":40.54,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43175825703002,"sku":"BWCS-GRA600PW-2","price":48.65,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43175825735770,"sku":"BWCS-GRA600PW-3","price":54.73,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-GRA600PW_1.webp?v=1775236298","url":"https:\/\/batteryweb.com\/products\/hedge-trimmer-st6-replacement-battery-72v-3600mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
