These are compact portable Wi-Fi hotspot devices that share the same battery bay and connector. Capacity is 7.77Wh — identical to the original specification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eSpot 4G and Apollo 4G shared battery platform:\u003c\/strong\u003e\n    Both the Spot 4G and Apollo 4G variants use the same 3.7V cell, connector pinout, and BMS handshake — the hardware is nearly identical under the lid, which is why Clear used one battery SKU across the range.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through charge and discharge cycles with the hotspot active under a four-device Wi-Fi load. The BMS reported clean state-of-charge data to the firmware, and no low-voltage cutoff trips occurred during normal draw.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eVentilation during active sessions:\u003c\/strong\u003e\n    Keep the hotspot on a hard, open surface when running extended sessions. When connected devices are far from the unit, the cellular radio ramps to full output power — that sustained RF load generates heat that sits directly against the battery if airflow is blocked.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the Spot 4G drops connected devices mid-session on a new battery\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eWhen all four Wi-Fi client slots are active and the cellular signal is weak, the modem and Wi-Fi radio draw power simultaneously at close to peak load. A cell with any internal resistance — even a new one that hasn't been fully conditioned — can sag below the BMS cutoff threshold under that combined spike. The hotspot firmware interprets this as a low-battery event and resets the radio stack, dropping all clients. Running the first two charge cycles without a heavy device load lets the cell stabilise its internal resistance before full deployment.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eHotspot shows a charge level but won't boot after sitting unused\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eAfter several weeks in storage, the cell can self-discharge below the minimum boot voltage — typically under 3.0V for this chemistry. The device may show a low battery icon or nothing at all, even though the battery isn't physically dead. Plug the hotspot into a USB wall charger rated at least 1A and leave it connected for 30–45 minutes before attempting to power on. If the device still won't boot, check the charging port and cable — the BMS needs a sustained input above 4.0V to re-initialise from deep discharge.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43377869455450,"sku":"BWCS-HPS400RC-1","price":24.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43377869488218,"sku":"BWCS-HPS400RC-2","price":27.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43377869520986,"sku":"BWCS-HPS400RC-3","price":30.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-HPS400RC-1.webp?v=1778773918","url":"https:\/\/batteryweb.com\/products\/clear-hotspot-spot-4g-replacement-battery-37v-2100mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
