It matches the OEM part number A0356 and fits directly into the S70 battery compartment. Capacity is rated at 6.29Wh — identical to the original specification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eNevo S70 compatibility:\u003c\/strong\u003e\n    The S70 uses a single flat Li-ion cell at 3.7V nominal. The BMS inside the remote expects this voltage rail to operate the IR emitter and onboard processor. Swapping to any other voltage or chemistry causes the remote to under-perform or fail to power on.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through the S70's power circuit and confirmed the BMS handshake completes correctly. The IR output stage activated at expected voltage levels without triggering the low-battery shutoff prematurely.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eLi-ion storage tip for the S70:\u003c\/strong\u003e\n    If the S70 sits unused for several weeks, the Li-ion cell can drop below the BMS's minimum re-charge threshold. Remove the battery and store it separately if the remote won't be used for more than a month — Li-ion cells store better outside a device drawing any standby current.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the Nevo S70 shows no response immediately after a new battery install\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe most common cause is reversed polarity during install. The S70 battery compartment label can be easy to misread, and Li-ion cells installed backwards apply no voltage to the circuit — the remote stays completely dark. Remove the cell, check the positive terminal against the compartment diagram, and reseat it correctly. If the remote still doesn't respond, hold the power button for 10 seconds to clear any residual charge in the capacitors before retrying.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eNevo S70 needing to be aimed directly at devices that used to respond at an angle\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when battery voltage drops below the IR LED's minimum output threshold — the emitter still fires, but the signal is too weak to bounce off walls or reach sensors at wider angles. It's a capacity fade symptom, not a remote fault. A fresh cell at 3.7V nominal restores full IR output range. If the issue persists with a new battery, check for a stuck button creating a parasitic drain that's already pulling the new cell down.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43416103354458,"sku":"BWCS-NVS70RC-1","price":23.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43416103387226,"sku":"BWCS-NVS70RC-2","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43416103419994,"sku":"BWCS-NVS70RC-3","price":28.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-NVS70RC-1.webp?v=1779760285","url":"https:\/\/batteryweb.com\/products\/nevo-s70-replacement-battery-37v-1700mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
