It replaces OEM part IS588 and restores power to terminals that have become unreliable due to a degraded original cell. Voltage and capacity match the original spec exactly.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eAMP9000 platform fit:\u003c\/strong\u003e\n    The AMP9000 uses a dedicated battery bay with a connector and BMS handshake tied to the IS588 specification. This replacement matches the voltage rail and physical dimensions (66.20 × 21.70 × 18.60mm) the terminal expects, so the charge IC recognises the cell and completes initialisation normally.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through the AMP9000 boot sequence and a simulated transaction load — display on, wireless active, receipt printer firing. The BMS held without triggering an overcurrent cutoff across repeated print cycles.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-use calibration tip:\u003c\/strong\u003e\n    Complete one full transaction cycle after installation before deploying the terminal in a live environment. The AMP9000 maps battery capacity during normal operation and needs at least one complete power cycle to report the charge indicator accurately on screen.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the AMP9000 reboots mid-transaction after a battery swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe receipt printer motor draws a sharp current spike the moment it fires — on a new cell, the BMS can interpret this as an overcurrent event and cut power to protect the cell. This is more common in the first few cycles before the BMS has profiled the cell's internal resistance. Running several test transactions off a live environment allows the BMS to register the printer's load signature and stop tripping. If reboots continue past five cycles, check that the battery connector is fully seated.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eAMP9000 not powering on after sitting unused in storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-ion cells self-discharge slowly during storage. If the terminal has sat unused for several months with a depleted battery inside, the cell voltage may have dropped below the BMS recovery threshold — typically under 2.5V — and the terminal will not respond to the power button. Connect the terminal to a working charger and leave it for 20–30 minutes without pressing anything. Most BMS circuits include a trickle-charge recovery mode that brings the cell back above the 3.0V threshold needed to boot.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43415926964314,"sku":"BWCS-NEP6210BL-1","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43415926997082,"sku":"BWCS-NEP6210BL-2","price":28.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43415927029850,"sku":"BWCS-NEP6210BL-3","price":31.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-NEP6210BL-1.webp?v=1779758086","url":"https:\/\/batteryweb.com\/products\/amp-amp9000-replacement-battery-37v-2600mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
