It fits units that use the BT10 or BT20 pack. The 21.6Wh capacity supports extended field sessions between charges.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eBT10 and BT20 cross-compatibility:\u003c\/strong\u003e\n    Both part numbers share the same 6V cell configuration, connector pinout, and BMS handshake protocol. HITARGET instruments that accept either OEM pack will accept this replacement without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack under simulated sensor-load draw and monitored BMS response at probe initialisation. The BMS held steady through the start-up current spike without tripping into protection mode.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-use calibration cycle:\u003c\/strong\u003e\n    After installing, run a full calibration cycle through the instrument menu before field deployment. The instrument maps battery state during calibration — skipping this step causes premature low-battery warnings on your first measurement session.\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 instrument 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 4.8V total across cells, the BMS can enter a low-voltage lockout state and refuse to accept a charge signal. This happens because the protection circuit treats deep-discharged cells as a fault condition. To recover, place the pack on a Ni-MH charger that supports a trickle pre-charge — most quality chargers apply a low 100–200mA recovery current until cell voltage climbs above the BMS acceptance threshold, typically around 5.4V, before switching to normal charge rate.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eReadings drifting or logging session resetting mid-measurement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eSustained sensor load — particularly when multiple probes or modules are active simultaneously — draws more current than idle display operation. If cell impedance has risen due to age or storage, voltage sags under this load and the instrument interprets the drop as a low-battery condition, triggering a save-and-reset cycle mid-log. A fresh pack with low internal resistance holds voltage steady under the combined draw. If dropouts persist after installing a new pack, check that the battery contacts in the instrument bay are clean and making full contact — oxidised contacts add resistance and replicate the same voltage sag symptom.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43360790577242,"sku":"BWCS-GBE121SL-1","price":51.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43360790610010,"sku":"BWCS-GBE121SL-2","price":60.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43360790642778,"sku":"BWCS-GBE121SL-3","price":66.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-GBE121SL-1.webp?v=1778616259","url":"https:\/\/batteryweb.com\/products\/hitarget-replacement-battery-6v-3600mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
