It fits the 38DL Plus series using OEM part numbers 38-BAT, CW-38-BAT, and Epoch4. The pack slots into the same battery bay and connects via the original interface without modification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003e38DL Plus and Epoch4 platform compatibility:\u003c\/strong\u003e\n    These instruments share the same 10.8V battery rail, connector pinout, and BMS handshake protocol. A single pack covers both device families without any adapter or wiring change.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this pack through the 38DL Plus power-on sequence, probe initialisation, and sustained measurement logging. The BMS held stable across the current spike at transducer power-up and did not trip during continuous scan sessions.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eCalibration cycle after installation:\u003c\/strong\u003e\n    After fitting a new pack, run a full calibration cycle through the instrument menu before field deployment. The 38DL Plus maps battery state during calibration — skipping this step causes premature low-battery warnings to appear during your first measurement session, even with a 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 cutoff when the transducer initialises on power-up\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe 38DL Plus sends a short high-current pulse to the probe module during initialisation. On a degraded or deeply discharged pack, this spike can trip the BMS overcurrent threshold before the instrument reaches its home screen. The pack is not faulty — the BMS has latched into protection mode. Charge the battery to at least 11.5V before reinserting, then power on without a probe attached first to let the instrument boot fully before connecting the transducer.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eReadings resetting or drifting mid-session during continuous logging\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eDuring extended logging runs, sustained sensor load can cause a brief voltage dropout if the cell is below 50% capacity. The 38DL Plus interprets this dropout as a power event and resets the active measurement session. This is not a firmware fault — it is a voltage sag issue at the cell level. Keep the pack above 11.1V during long field sessions, or carry a second charged battery and swap at the halfway point rather than running the pack to depletion.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43360532529242,"sku":"BWCS-OPS380SL-1","price":37.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43360532562010,"sku":"BWCS-OPS380SL-2","price":43.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43360532594778,"sku":"BWCS-OPS380SL-3","price":47.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-OPS380SL-1.webp?v=1778615946","url":"https:\/\/batteryweb.com\/products\/olympus-38dl-plus-ultrasonic-thickness-gauge-replacement-battery-108v-2600mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
