It slots directly into the same battery bay and communicates with the same BMS handshake the charger expects. Capacity figures come from the product data, not manufacturer marketing sheets.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003e82V platform compatibility:\u003c\/strong\u003e\n    All listed models run the same 80V nominal rail, share the same battery connector, and use the same BMS communication protocol — which is why one pack covers the full range 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 blade-motor inrush cycles on the 82V platform. The BMS held cutoff thresholds within spec and recovered correctly after load spikes consistent with thick-grass engagement.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eSeasonal storage before first mow:\u003c\/strong\u003e\n    If the battery sat in an unheated garage through winter, bring it indoors for at least 12 hours before the first spring charge. Cold Li-ion cells have elevated internal resistance, and the blade motor's inrush current can trip the BMS on a pack that hasn't warmed to room temperature.\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 thick-grass or wet-grass blade load\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eWhen the blade hits dense or wet grass, motor inrush current spikes sharply — sometimes two to three times the steady-state draw. The BMS on the 82V platform is set to cut power if that spike exceeds the pack's rated discharge threshold. This protects the cells from a single high-current event that would otherwise cause permanent capacity loss. If the mower shuts off mid-row and the battery LED flashes, set it down for five minutes to let the BMS thermal sensor reset before restarting.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCharger shows fault light after the pack sat unused all winter\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-ion cells self-discharge slowly over months. If the pack drops below roughly 2.5V per cell during storage, most chargers will refuse to begin a charge cycle — they read the voltage as a fault condition rather than a deeply discharged pack. Some Cramer 82V chargers include a recovery mode: hold the charge button for five seconds to force a low-current pre-charge that brings cell voltage back above the acceptance threshold. If the charger has no recovery mode, check cell voltage with a multimeter — anything above 2.0V per cell is usually recoverable with a compatible recovery charger set to 80V.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381303705690,"sku":"BWCS-GWP800PW-1","price":68.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381303738458,"sku":"BWCS-GWP800PW-2","price":80.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381303771226,"sku":"BWCS-GWP800PW-3","price":88.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-GWP800PW-1.webp?v=1778899964","url":"https:\/\/batteryweb.com\/products\/cramer-82v-82b900-replacement-battery-80v-2000mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
