It fits professional surveying instruments, handheld measurement devices, and field diagnostic tools that run on the DR10 form factor. Voltage and capacity match the original spec: 6V, 2100mAh (12.6Wh).\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eSurvey and measurement instrument fit:\u003c\/strong\u003e\n    These tools share the DR10 because they run the same 6V rail with a BMS handshake tuned to Ni-MH discharge curves. The connector layout and cell geometry are matched to the original housing, so the pack seats correctly 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 charge and discharge under a sustained sensor load. The BMS held within expected cutoff thresholds and recovered correctly from a simulated low-voltage state without requiring a manual reset.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eCalibration cycle after install:\u003c\/strong\u003e\n    After fitting this pack, run a full calibration cycle through the instrument menu before field deployment. The instrument maps battery state during calibration, and skipping this step causes premature low-battery warnings during 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 — typically 1–3% per day depending on temperature. If the pack sat long enough, cell voltage can drop below the BMS recovery threshold, and the pack will appear dead even when placed on a charger. Most chargers detect this as a fault and stop the charge cycle immediately. Connect the pack to a known-good Ni-MH charger that supports a trickle or recovery mode, which pushes a low current (around 0.1C) until cell voltage rises back above the 5.4V recovery floor before switching to full charge.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eInstrument shuts down mid-measurement with no low-battery warning\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eWhen a probe or sensor module initialises, it draws a short current spike that can exceed the BMS overcurrent threshold — especially if cell impedance has risen after partial discharge. The BMS trips as a protective cutoff, and the instrument loses power without any prior warning on the display. This is not a faulty pack; it is the BMS responding correctly to an instantaneous load it was not expecting. Charge the pack to full before the session and verify cell voltage sits above 6.0V before powering on sensor-heavy modules.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43360787791962,"sku":"BWCS-PMB02SL-1","price":39.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43360787824730,"sku":"BWCS-PMB02SL-2","price":46.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43360787857498,"sku":"BWCS-PMB02SL-3","price":51.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-PMB02SL-1.webp?v=1778616277","url":"https:\/\/batteryweb.com\/products\/duracell-replacement-battery-6v-2100mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
