It fits the P2000L directly and uses OEM part number 335880. Swap it in when the original cell no longer holds charge through a full merchant shift.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eP2000L platform fit:\u003c\/strong\u003e\n    The P2000L uses a fixed 7.4V two-cell Li-ion pack with a BMS that validates cell voltage and connector polarity at boot. This replacement matches that voltage rail and connector pinout, so the terminal completes its PCI boot handshake without errors.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this battery through repeated boot sequences and simulated transaction loads — receipt printer pulses, card reader draws, and wireless pings together. The BMS held the voltage rail steady and did not trip under combined draw.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst deployment tip for POS terminals:\u003c\/strong\u003e\n    After installation, complete one full transaction cycle before going live. The P2000L maps battery capacity during normal operation and needs at least one complete power cycle to calibrate the charge indicator correctly.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003ePayment terminal rebooting mid-transaction after battery swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe P2000L's receipt printer motor pulls a short current spike — typically 1.5–2A — each time it fires. On a new battery with a conservative BMS, that spike can trip the overcurrent threshold before the BMS learns the load profile. This usually clears after two or three full transaction cycles as the BMS adjusts its overcurrent window. If reboots continue past five transactions, check that the battery contacts are fully seated and the terminal firmware is current.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eP2000L not powering on after sitting unused in storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-ion cells left uncharged for several months can drop below 2.5V per cell — the point where most BMS circuits lock the pack into a protection state and refuse to discharge or charge normally. Plug the terminal into its dock and leave it on charge for at least 90 minutes before attempting to power it on. Most BMS circuits will accept a slow trickle charge from the dock and recover the cell voltage above the 3.0V unlock threshold. If the terminal still shows no response after two hours on the charger, the original cell is likely below recovery voltage — this replacement pack starts at a safe storage charge and will not exhibit this fault.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43415919263834,"sku":"BWCS-TLP200BL-1","price":53.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 2 Year","offer_id":43415919296602,"sku":"BWCS-TLP200BL-2","price":63.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 3 Year","offer_id":43415919329370,"sku":"BWCS-TLP200BL-3","price":70.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-TLP200BL-1.webp?v=1779757974","url":"https:\/\/batteryweb.com\/products\/tactilion-p2000l-replacement-battery-74v-2000mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
