It fits the rugged outdoor watch platform that combines multi-GNSS tracking with solar charging. Swap it when the original cell no longer holds charge through a full day of GPS-active use.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eInstinct Solar GPS fit:\u003c\/strong\u003e\n    The Instinct Solar GPS runs a single-cell Li-Po rail at 3.8V nominal. This cell matches the original footprint at 27.00 × 19.90 × 3.50mm and carries the same BMS handshake expected by the fuel gauge IC on this platform.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through GPS-active and solar-supplemented charge states on the Instinct Solar platform. The BMS accepted the cell without fault codes, and the fuel gauge IC reported accurately after a full calibration charge.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-swap charge cycle on the Instinct Solar:\u003c\/strong\u003e\n    Place the watch on its magnetic charger immediately after fitting this cell and charge to 100% before use. The fuel gauge IC on this platform loses its reference point during a cell swap and cannot report accurately without completing one full charge cycle from near-zero.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the Instinct Solar GPS reads 0% right after a battery swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Instinct Solar uses a coulomb-counting fuel gauge IC that tracks charge state relative to a stored reference. Removing the old cell clears that reference entirely. When a new cell is fitted, the IC has no baseline, so it defaults to 0% or a random low value regardless of actual cell voltage. This is not a fault with the replacement cell. Charging to 100% on the magnetic charger immediately after the swap resets the IC and restores accurate percentage readings.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCharge contacts not making on the magnetic charger after reassembly\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Instinct Solar's magnetic charge contacts sit flush against the rear case, and reassembly pressure can shift their alignment by a fraction of a millimetre. If the watch does not begin charging when placed on the charger post-swap, the contacts are likely misaligned rather than faulty. Remove the watch from the charger, re-seat the rear case firmly, and recheck contact position. A correctly seated watch will show the charging icon within 10 seconds of contact at the standard 5V charge input.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43416155127898,"sku":"BWCS-GMS100SL-1","price":35.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43416155160666,"sku":"BWCS-GMS100SL-2","price":41.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43416155193434,"sku":"BWCS-GMS100SL-3","price":45.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-GMS100SL-1.webp?v=1779760505","url":"https:\/\/batteryweb.com\/products\/garmin-instinct-solar-gps-replacement-battery-38v-200mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
