It replaces OEM part 584 84 28-02 and cross-references across more than 30 Husqvarna part numbers. Voltage and form factor match the original pack exactly.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003e115H, 305, 310 and 315 2020 series:\u003c\/strong\u003e\n    These models share the same 18V battery rail, connector pinout, and BMS handshake protocol. One pack covers the full range — no adapter or firmware change needed.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this pack through a full charge-discharge cycle on the 115H platform. The BMS communicated correctly with the charger, accepted a full charge without fault codes, and delivered consistent voltage under simulated blade load.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eSeasonal start-up care:\u003c\/strong\u003e\n    Before the first cut of the season, bring the battery indoors overnight if temperatures are below 10°C. Cold Li-ion cells carry higher internal resistance, and the blade motor's inrush current can trip the BMS on a cold pack before it even starts cutting.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBMS cutoff during thick or wet hedge cutting\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eDense branches and wet growth force the blade motor to draw significantly more current than normal cutting load. If that spike exceeds the BMS current threshold, the pack shuts down as a protection response — not a fault. The battery resets once it cools. Keeping the blade clean and moving at a consistent pace reduces the load spikes that trigger this cutoff.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCharger rejecting the pack after sitting unused all winter\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-ion cells self-discharge over months of storage. If the pack drops below roughly 2.5V per cell, most chargers will refuse to accept it — the charger reads the voltage as outside the safe charge window and shows a fault light. Some chargers include a recovery or \"wake-up\" mode that applies a low-current trickle to bring the cells back into range. If yours does not, measure cell voltage with a multimeter — individual cells above 2.0V can often be recovered; below that, replacement is the safer call.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381293940826,"sku":"BWCS-HTA115PW-1","price":81.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381293973594,"sku":"BWCS-HTA115PW-2","price":95.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381294006362,"sku":"BWCS-HTA115PW-3","price":106.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-HTA115PW_1.webp?v=1778899901","url":"https:\/\/batteryweb.com\/products\/husqvarna-115h-2020-replacement-battery-18v-2500mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
