It matches the original voltage rail, connector, and BMS communication protocol those platforms require. Also cross-references OEM part numbers LI202S-NT-4600 and LI202S-NT-46A.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eCMA-5000 and CMA-5000A compatibility:\u003c\/strong\u003e\n    Both models share the same battery bay geometry, 14.4V supply rail, and BMS handshake protocol — a single pack covers both. The connector pinout and charge termination signalling are identical across the CMA-5000 and CMA-5000A hardware revisions.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this pack under sustained RF signal analysis load and confirmed that the BMS holds the voltage rail stable through repeated probe-module initialisation cycles without triggering an overcurrent cutoff.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePre-deployment calibration cycle:\u003c\/strong\u003e\n    After installing this pack, run a full calibration cycle through the CMA-5000 instrument menu before taking it into the field. The instrument maps battery state during calibration — skipping this step causes premature low-battery warnings during your first measurement session, even at near-full charge.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBMS lockout after the CMA-5000 sat unused in a carry case for months\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eLi-ion packs in test instruments self-discharge during storage. If the CMA-5000 sits unused long enough, the pack drops below the BMS recovery threshold — typically around 10–11V for a 14.4V four-cell series string. At that point the BMS latches into protection mode and the instrument will not respond to the power button or the charger. The fix is to apply a trickle charge to the pack directly using a bench supply set to 12V at 200mA for 15–20 minutes until the BMS releases, then transfer to the standard charger. Once the pack reads above 12.5V on the charger, normal CC\/CV charge resumes.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCMA-5000 display showing an inconsistent battery percentage at every reboot\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe CMA-5000 reads battery state against voltage thresholds stored during previous pack use — when a new or replacement pack is installed, those stored thresholds no longer match the new cell's charge curve. The instrument reports wildly different percentages on successive boots because it is still referencing the old calibration map. Running the full instrument calibration sequence from the system menu forces the CMA-5000 to remap its voltage-to-percentage thresholds against the new pack's actual discharge curve. After one complete calibration cycle, the percentage readout stabilises across reboots.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43360669794394,"sku":"BWCS-AMT500SL-1","price":65.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43360669827162,"sku":"BWCS-AMT500SL-2","price":76.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43360669859930,"sku":"BWCS-AMT500SL-3","price":84.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-AMT500SL-1.webp?v=1778616161","url":"https:\/\/batteryweb.com\/products\/anritsu-nettest-cma-5000-replacement-battery-144v-5200mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
