It replaces OEM part numbers 4 932 353 638, 4 932 366 429, B9.6, BX9.6, BXS9.6, and MX9.6. Capacity is rated at 3300mAh (31.68Wh) and matches the original voltage rail these tools require.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003ePCS6T and PES9.6 platform compatibility:\u003c\/strong\u003e\n    Both the PCS6T and PES9.6 variants run on the same 9.6V sub-C cell stack with a shared connector footprint and identical BMS handshake protocol. One pack covers all three models listed 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 full charge-discharge sequences on the PCS6T platform and monitored the BMS response to motor-start inrush current. The protection circuit held stable through repeated trigger pulls at full torque without nuisance tripping.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBreak-in cycle for inrush profiling:\u003c\/strong\u003e\n    On first use, run the tool at half load for two cycles before pushing maximum torque. This allows the BMS to profile the motor's inrush current draw and set overcurrent thresholds accurately before you hit full fastening loads.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBMS cutoff on motor-start inrush during heavy fastening\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eNi-MH packs at 9.6V carry a relatively low cell count, which means the BMS has less voltage headroom to absorb the inrush spike when the PCS6T motor engages under load. If the pack has been sitting discharged, internal resistance rises and the inrush spike can push the BMS over its overcurrent threshold instantly. This triggers a protective cutoff that looks like the tool dying mid-use. Letting the pack complete a full charge cycle before heavy use reduces internal resistance and keeps the inrush within the BMS trip window.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eTool bogs down under sustained load but recovers when you release the trigger\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is voltage sag — not a dead pack. Under sustained motor load, cell voltage drops below the tool's operating threshold, causing the motor to slow or stall. When the trigger releases, the pack recovers and voltage reads normal again. The most common cause is high contact resistance at the battery rail, either from oxidised terminals or a loose pack seating. Clean the battery contacts with isopropyl alcohol, reseat the pack firmly, and check that resting voltage reads at least 10.2V before dismissing the pack itself as the fault.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43416062263386,"sku":"BWCS-MKE535PX-1","price":81.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43416062296154,"sku":"BWCS-MKE535PX-2","price":94.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43416062328922,"sku":"BWCS-MKE535PX-3","price":104.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-MKE535PX-1.webp?v=1779760040","url":"https:\/\/batteryweb.com\/products\/atlas-copco-pcs6t-replacement-battery-96v-3300mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
