It replaces OEM part SE-15-43 Rev C. Both instruments use this pack to power optical measurement and ink density analysis during portable field and press-side use.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003e331C and 341C compatibility:\u003c\/strong\u003e\n    Both models share the same battery bay, connector pinout, and 4.8V supply rail. The BMS handshake is identical across the two, so one pack covers either instrument without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through measurement sequences on the 331C, monitoring BMS response at sensor initialisation. The pack handled repeated optical module power-up draws without tripping the protection circuit.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eCalibration cycle after install:\u003c\/strong\u003e\n    Run a full calibration cycle through the instrument menu before field deployment. The 331C maps battery state during calibration — skipping this step causes premature low-battery warnings during your first measurement session, even when the pack is fully charged.\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 331C sat unused in a carry case for months\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNi-MH cells self-discharge during storage. If the pack drops below roughly 3.6V total, the protection circuit locks out to prevent cell reversal. When you plug in the charger, nothing happens — the BMS is blocking charge current, not the charger itself. Place the pack on a Ni-MH compatible charger that supports a low-current recovery mode, typically 100–200mA, and hold it there until the circuit releases. Once voltage climbs above 4.0V, the BMS re-enables normal charge current and the instrument accepts the pack again.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003e331C shuts down mid-measurement even though the battery indicator showed full\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe 331C's voltage threshold indicator reads resting voltage, not voltage under load. During an active optical measurement, the sensor and display draw sustained current that causes a brief voltage sag. If cell capacity has degraded — even in a pack that reads full at rest — that sag trips the low-voltage cutoff and the instrument shuts off mid-sequence. The fix is a full charge followed by a complete discharge cycle to reset the instrument's voltage reference. After one conditioning cycle, the low-battery warning should align accurately with actual remaining capacity.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43360434618458,"sku":"BWCS-XRT331SL-1","price":43.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43360434651226,"sku":"BWCS-XRT331SL-2","price":51.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43360434683994,"sku":"BWCS-XRT331SL-3","price":56.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-XRT331SL-1.webp?v=1778614781","url":"https:\/\/batteryweb.com\/products\/x-rite-331c-densitometer-replacement-battery-48v-2000mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
