It replaces OEM part number 68305001. These remotes are used in industrial lifting and material handling — the battery is the only power source for all control signals sent to the hoist or crane.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eHH-S, HH-M, and HH-L compatibility:\u003c\/strong\u003e\n    All three models run the same 3.6V single-cell Ni-MH architecture with identical connector placement and BMS handshake protocol. One battery pack covers the full HH series without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through repeated solenoid-activation sequences on the HH-S platform. The BMS held stable through inrush current spikes and returned to nominal voltage within expected recovery windows.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eMonthly charge during idle periods:\u003c\/strong\u003e\n    Crane remotes often sit unused for weeks between jobs. Ni-MH cells self-discharge at roughly 1–3% per day. A battery left uncharged for two months can drop below the BMS recovery threshold — charge the pack once a month even when the remote is shelved.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eSolenoid activation causing power dropout on a freshly installed battery\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eWhen the HH-S remote triggers a solenoid or relay on the crane, inrush current spikes hard and fast. A Ni-MH cell at storage voltage — around 1.1V — has limited peak-current delivery and the BMS may interpret the sag as a fault and cut output. This is not a defective battery. The fix is to fully charge the pack before the first activation cycle. A full charge brings internal resistance down and allows the cell to supply the brief current surge without tripping the protection circuit.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eRemote showing low battery immediately after swapping in a new cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eA new Ni-MH pack ships at storage voltage, typically 1.1–1.2V per cell — below the threshold the HH remote firmware reads as \"full.\" The remote reports low battery because that reading is accurate at that voltage. This is not a fault with the pack. Connect the remote to its charger and run a complete charge cycle before use; the low-battery indicator should clear once the cell reaches 1.4V or above.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43360045269082,"sku":"BWCS-HTR683BL-1","price":53.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43360045301850,"sku":"BWCS-HTR683BL-2","price":63.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43360045334618,"sku":"BWCS-HTR683BL-3","price":70.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-HTR683BL-1.webp?v=1778610710","url":"https:\/\/batteryweb.com\/products\/hetronic-hh-s-replacement-battery-36v-2000mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
