It fits the A5, A6, A8, and Q3 platforms. Voltage and cell count match the original pack exactly.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eA5 \/ A6 \/ A8 \/ Q3 platform compatibility:\u003c\/strong\u003e\n    These four models share the same 11.1V three-cell architecture, identical connector pinout, and BMS communication protocol — which is why one pack covers the range. The protection circuit responds to the same charge termination signals as the OEM unit.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through charge, load draw, and BMS cutoff verification. The protection circuit tripped correctly at low-voltage cutoff and recovered cleanly on reconnection to the charger. Charge termination voltage hit within 0.05V of spec.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-installation self-test cycle:\u003c\/strong\u003e\n    After fitting this battery, allow the device to complete its full power-on self-test without interruption. Bolate medical devices run a BMS verification routine at startup — cutting power mid-sequence flags a false battery fault that persists until the next full reboot.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eDevice not completing boot sequence on new battery\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eBolate devices run a startup BMS handshake that checks cell voltage before completing the boot sequence. A new cell that has partially self-discharged during storage may present a resting voltage just below the threshold the device expects at power-on. The device interprets this as a degraded or incompatible pack and halts boot. Charge the battery fully — to at least 12.4V resting — before the first power-on attempt.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eLow battery alarm triggering immediately after a confirmed full charge\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens because the device's charge IC applies a conservative capacity estimate on the first cycle with a new cell — the BMS has not yet learned the actual capacity curve of the replacement pack. The alarm threshold is calculated against an incomplete state-of-charge map, so it triggers early even when the cell is genuinely full. Run one complete charge-to-discharge-to-charge cycle before relying on the battery indicator. After that first full cycle, the BMS recalibrates and the alarm threshold aligns correctly.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381475999834,"sku":"BWCS-BLA500MD-1","price":154.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381476032602,"sku":"BWCS-BLA500MD-2","price":180.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381476065370,"sku":"BWCS-BLA500MD-3","price":199.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-BLA500MD-1.webp?v=1778901051","url":"https:\/\/batteryweb.com\/products\/bolate-a5-replacement-battery-111v-5200mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
