It fits the TPS2012B, TPS2014B, TPS2024B, and related TPS2000B variants. Capacity and voltage match the original NI2040 specification exactly.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eTPS2000B series compatibility:\u003c\/strong\u003e\n    All TPS2000B-series scopes share the same 11.1V three-cell Li-ion architecture, physical battery bay, and BMS communication protocol. One pack covers the full line because the charge IC and connector pinout are identical across TPS2012B, TPS2014B, and TPS2024B variants.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through charge and discharge on a TPS2014B. The BMS accepted the cell stack without fault codes, balanced across all three cells within the first full charge, and the scope reported battery status correctly throughout the test sequence.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePower-on self-test after installation:\u003c\/strong\u003e\n    After fitting this battery, let the TPS2000B complete its full startup self-test without interruption. The instrument runs a BMS verification pass at boot. Cutting power during this sequence logs a false battery fault that persists until the next complete reboot cycle.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the TPS2000B reports a battery fault after a fresh cell is installed\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe TPS2000B charge IC applies conservative acceptance thresholds calibrated to a known OEM cell profile. A new third-party cell can present slightly different internal resistance and initial resting voltage, which the BMS flags as out-of-range on first contact. This is not a hardware fault — it clears after one full charge-discharge cycle as the BMS maps the actual cell characteristics. Run one complete charge to full, then discharge under normal scope use before trusting the battery status indicator for field work.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCharge indicator stalls below 100% on the first charge\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eOn the first charge, the TPS2000B charge IC holds the cell at a reduced current ceiling until it confirms cell chemistry matches expected parameters. This causes the on-screen indicator to plateau at 90–95% and stop climbing. The cell is still taking charge — the IC is running a slow top-up verification pass, not stalling. Leave the scope on charge undisturbed; the indicator typically reaches 100% once internal resistance drops below the IC's acceptance threshold, usually after the resting voltage stabilises above 12.4V.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381497856090,"sku":"BWCS-HVA710MD-1","price":208.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381497888858,"sku":"BWCS-HVA710MD-2","price":248.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381497921626,"sku":"BWCS-HVA710MD-3","price":277.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-HVA710MD-1.webp?v=1778901266","url":"https:\/\/batteryweb.com\/products\/tektronix-tps2000b-replacement-battery-111v-7800mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
