It fits the 1060, 6430, 5050, and 5070 series, among others. OEM part numbers 2960.21 and 525832D00 cross-reference directly to this pack.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003e1060 \/ 6430 \/ 5050 \/ 5070 compatibility:\u003c\/strong\u003e\n    These models share the same 9.6V rail, connector footprint, and BMS handshake protocol — one pack covers the full group without modification or adapter.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack under sustained sensor and probe load. The BMS held steady through probe initialisation spikes and sustained logging draws without tripping into cutoff.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-install calibration step:\u003c\/strong\u003e\n    After fitting this pack, run a full calibration cycle through the instrument menu before field use. The instrument maps battery state during calibration — skipping it causes premature low-battery warnings on the 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\n  \u003cp class=\"bpw-desc-p\"\u003eNi-MH cells self-discharge during storage. If the pack drops below approximately 0.9V per cell, the BMS enters a protective sleep state and the instrument shows no response on power-up. A standard charger may refuse to initiate a charge cycle because it reads the pack voltage as too low to be a valid battery. Most smart chargers have a recovery or \"boost\" mode that applies a low-current trickle until the pack reaches a safe threshold — typically around 8.0V — before switching to normal charge. Once the pack recovers to that level, a standard charge cycle completes normally.\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\"\u003eUnder sustained sensor load — particularly when multiple probe channels are active simultaneously — pack voltage can sag momentarily below the instrument's operating floor. The instrument interprets this voltage dropout as a shutdown event rather than a transient, which resets the active logging session. This is more common with aged cells but can also occur with a new pack that has not been fully conditioned. Run two full charge-discharge cycles before a long field session, and confirm resting voltage sits at or above 9.6V before deployment.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43360727564378,"sku":"BWCS-AMC650SL-1","price":75.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43360727597146,"sku":"BWCS-AMC650SL-2","price":88.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43360727629914,"sku":"BWCS-AMC650SL-3","price":97.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-AMC650SL-1.webp?v=1778616209","url":"https:\/\/batteryweb.com\/products\/chauvin-arnoux-1060-replacement-battery-96v-3500mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
