It matches the OEM TB-800Li specification and fits the G1 battery compartment directly. Voltage and capacity are sourced from the original part data, not estimated.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eGOTOP G1 compatibility:\u003c\/strong\u003e\n    The G1 uses a compact single-cell Li-ion pack at 3.7V nominal. The TB-800Li form factor — 35.02 × 33.62 × 10.20mm — matches the OEM bay. The BMS on this camera checks voltage presence at insertion, not a proprietary handshake, so a correctly sized cell at the right voltage is accepted without special pairing.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through charge and discharge under G1-class loads. The protection circuit triggered correctly at the low-voltage cutoff and the camera's battery indicator tracked the discharge curve without jumping on the first full cycle.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-cycle calibration on the G1:\u003c\/strong\u003e\n    After installing a new TB-800Li, run one complete charge through the camera body or OEM charger before your first shoot. Some G1 units map the battery-remaining display against a baseline charge profile stored from the first cycle — skipping this step can cause the indicator to read inaccurately for the first few sessions.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBattery percentage jumping on the G1 display after fitting a new cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe G1's battery gauge maps voltage thresholds from its OEM discharge curve to generate a percentage readout. A new replacement cell has a slightly different discharge profile, especially in the mid-range between 3.6V and 3.9V. This mismatch causes the indicator to skip steps or jump backward during the first few cycles. After two or three full charge-discharge cycles, the gauge stabilises and tracks the new cell accurately.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eG1 showing dead battery icon on a replacement cell with charge remaining\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the camera reads the cell's resting voltage immediately after a discharge event and interprets it as critically low before the cell has recovered. Li-ion cells at 850mAh capacity show a temporary voltage dip under load that can touch the camera's low-battery threshold. Remove the battery, wait 60 seconds, and reinsert — resting voltage typically recovers to above 3.5V and the camera resumes normal operation. If the icon persists after recovery time, put the cell on charge until it reaches a full 4.2V before shooting again.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43333644681306,"sku":"BWCS-GTP100MC-1","price":31.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43333644714074,"sku":"BWCS-GTP100MC-2","price":34.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43333644746842,"sku":"BWCS-GTP100MC-3","price":38.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-GTP100MC-1.webp?v=1778213017","url":"https:\/\/batteryweb.com\/products\/gotop-g1-replacement-battery-37v-850mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
