The ACS800 uses this battery pack to deliver portable intermittent pneumatic compression therapy for DVT prevention and patient mobility. Voltage and capacity match the OEM specification: 14.8V, 5200mAh (76.96Wh).\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eFlowtron ACS800 platform fit:\u003c\/strong\u003e\n    The ACS800 uses a 14.8V four-cell Li-ion configuration with a specific BMS handshake that governs charge acceptance and discharge cutoff. This pack matches that voltage rail and connector pinout so the device's charge circuit communicates correctly with the battery from first power-on.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this battery through the ACS800's full charge-to-discharge profile. The BMS reported state-of-charge accurately across all test cycles, and the pack held voltage under the compression pump's load surges without triggering low-voltage cutoff prematurely.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePower-on self-test after installation:\u003c\/strong\u003e\n    After fitting this battery, allow the ACS800 to complete its full power-on self-test cycle without interruption. The device runs a BMS verification sequence at startup — cutting power mid-sequence registers 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\"\u003eWhy the ACS800 alarms low battery immediately after a confirmed full charge\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe ACS800's charge IC applies a conservative acceptance threshold calibrated to the OEM cell's chemistry fingerprint. A new replacement cell hasn't yet established a charge history the BMS recognises, so the device reports low battery even when the pack is fully charged. This isn't a fault with the battery — it resolves after one complete charge-discharge cycle. Run the device through a full cycle before clinical use, and the BMS will re-register the pack's actual capacity correctly.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eACS800 won't power on after battery sat unused in storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-ion cells self-discharge during storage, and if the pack drops below the ACS800's BMS recovery threshold — typically around 2.5V per cell — the device will not power on and the charger may show no activity. Place the battery on charge for at least 30 minutes before attempting to power the device. Most BMS circuits include a trickle-recovery mode that brings the cell voltage back above the 3.0V-per-cell threshold needed to re-enable full charging. If the charger shows no response after 30 minutes, check the pack voltage directly — below 10.0V total, the BMS may need a recovery charge from a compatible external source before the ACS800 charger takes over.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381438218330,"sku":"BWCS-ARH400MD-1","price":69.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381438251098,"sku":"BWCS-ARH400MD-2","price":82.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381438283866,"sku":"BWCS-ARH400MD-3","price":91.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-ARH400MD-1.webp?v=1778900837","url":"https:\/\/batteryweb.com\/products\/arjo-flowtron-acs800-replacement-battery-148v-5200mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
