It uses an INR18650 cell configuration and matches the voltage and capacity of the original pack. The WGI-1020 is used in clinical and home healthcare settings for patient monitoring and treatment support.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eWGI-1020 cell compatibility:\u003c\/strong\u003e\n    The WGI-1020 draws a consistent low-to-moderate load profile typical of portable medical equipment. The INR18650 cell chemistry handles that load without the voltage sag issues that older NiMH packs introduced in earlier-generation equivalents.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this pack through charge, idle, and active-load cycles on the WGI-1020. The onboard BMS communicated correctly with the device charge IC, and the protection circuit responded normally to both end-of-charge and low-voltage cutoff thresholds.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-swap self-test cycle:\u003c\/strong\u003e\n    After installing this battery, allow the WGI-1020 to complete its full power-on self-test without interruption. The device runs a BMS verification sequence at startup — cutting power mid-sequence flags a false battery fault that persists until the next complete reboot.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWGI-1020 not completing boot sequence on a new battery\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe WGI-1020 runs a startup verification check that reads cell voltage and BMS status before completing its boot cycle. A new cell shipped at partial state of charge can sit just below the threshold the device expects at power-on, causing the boot sequence to stall or restart. Charge the replacement battery fully before the first power-on. If the device still stalls, disconnect the battery, wait 30 seconds, reconnect, and allow a full uninterrupted boot.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCharge indicator not reaching 100% on first charge\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eOn the first charge cycle with a new cell, the WGI-1020 charge IC applies a conservative current limit while it profiles the pack. This is normal — the indicator can plateau at 90–95% before the charge IC confirms the cell is within expected parameters and releases the final top-up stage. Do not interrupt the charge. Complete two full charge-discharge cycles and the indicator will reach 100% as the charge IC learns the pack's actual capacity curve.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381363343450,"sku":"BWCS-WGR102MD-1","price":43.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381363376218,"sku":"BWCS-WGR102MD-2","price":51.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381363408986,"sku":"BWCS-WGR102MD-3","price":56.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-WGR102MD-1.webp?v=1778900304","url":"https:\/\/batteryweb.com\/products\/wego-wgi-1020-replacement-battery-74v-2600mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
