It stores the charge captured by the fixture's solar panel during the day and powers the light through the night. Capacity is 3600mAh (11.52Wh) — use the figure from the product data, not estimates from third-party sources.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eGS-97F-GE, GS-97N, GS-104, and GS-103 compatibility:\u003c\/strong\u003e\n    These fixtures share the same battery bay dimensions, 3.2V voltage rail, and BMS handshake protocol. The XML-323-GS cell fits all of them without modification to the holder or wiring harness.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through full solar-simulated charge and discharge runs. The BMS held the charge cutoff at the correct upper voltage and protected the cell against over-discharge at the low-voltage threshold — both critical for outdoor fixtures left unattended through seasonal changes.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePanel angle before installation:\u003c\/strong\u003e\n    Adjust the solar panel face to point directly at the sun's path — not just skyward. The fixture's BMS has a minimum input threshold; indirect or partial-shade light generates insufficient current to trigger charging, even on a bright day. Get the angle right before assuming the battery is at fault.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the GS-97F-GE dims or shuts off before dawn\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eLiFePO4 cells in solar fixtures operate on a fixed discharge curve. If the panel didn't push enough current during the day — due to cloud cover, shading, or a poor angle — the cell starts the night at 70–80% capacity instead of full. The fixture's controller doesn't know this; it drives the LED at normal output until the cell voltage drops below the cutoff threshold, then the light shuts off. Replacing a degraded cell that can no longer hold 3600mAh is the fix, but first confirm the panel is actually delivering adequate charge current.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eNew battery installed but the light still won't turn on at night\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eA fresh LiFePO4 cell ships at a storage voltage — typically around 3.0V — which may sit below the controller's operating threshold. The fixture needs a full daytime charge cycle before it will activate the LED output circuit. Place the unit in direct sunlight for a full day, then check at dusk. If the light still doesn't activate, measure the cell voltage with a multimeter: a healthy, charged LiFePO4 cell should read between 3.2V and 3.35V.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43416176033882,"sku":"BWCS-GNS970FT-1","price":30.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43416176066650,"sku":"BWCS-GNS970FT-2","price":35.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43416176099418,"sku":"BWCS-GNS970FT-3","price":39.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-GNS970FT-1.webp?v=1779760588","url":"https:\/\/batteryweb.com\/products\/gama-sonic-gs-97f-ge-replacement-battery-32v-3600mah-lifepo4","provider":"BatteryWeb","version":"1.0","type":"link"}
