It fits the WAVE2, WAVE2 S6, WAVE2 L10, and M880 RAY platforms. Swap it in when the original cell can no longer hold charge through a full shift.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eWAVE2 and M880 RAY transmitter family:\u003c\/strong\u003e\n    These remotes share the same battery bay geometry, connector orientation, and 3.7V nominal rail. The AS087 cell fits all listed transmitter variants without modification to the housing or contacts.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled the cell through charge and discharge on the bench, confirming the BMS holds cutoff correctly at low voltage and accepts a full charge without flagging a fault on the transmitter display.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eMonthly charge during idle storage:\u003c\/strong\u003e\n    Crane remotes often sit unused for weeks between jobs. Keep this cell above 3.0V by charging it once a month during any idle period — Li-ion cells that drop below 2.5V can trigger BMS lockout and will not recover even when a charger is connected.\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 a solenoid or relay fires, it draws a short inrush current spike that can exceed the BMS discharge threshold on a cell that is not at full charge. The BMS interprets that spike as an overcurrent event and cuts the output rail momentarily. This causes the remote to drop out or reset mid-command, which is dangerous on a live crane. Charge the new cell fully to 4.2V before putting the remote into service — a cell sitting at storage voltage around 3.7V does not have enough headroom to absorb that inrush without tripping the BMS.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eRemote showing low-battery warning immediately after new cell install\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eLi-ion cells ship at storage voltage, typically 3.6–3.7V, not at full charge. The WAVE2 transmitter reads cell voltage directly and flags anything below its low-battery threshold as a warning. This is not a fault with the cell — it is a storage state, not a depleted state. Connect the charger before first use and run the cell up to 4.2V; the warning will clear once the transmitter sees nominal operating voltage.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43360042778714,"sku":"BWCS-MBE370BL-1","price":53.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43360042811482,"sku":"BWCS-MBE370BL-2","price":63.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43360042844250,"sku":"BWCS-MBE370BL-3","price":70.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-MBE370BL-1.webp?v=1778610728","url":"https:\/\/batteryweb.com\/products\/imet-wave2-replacement-battery-37v-1800mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
