It matches the OEM part number BS2E7.2T and fits the PES7.2T platform's battery bay and connector layout. Capacity is 3300mAh — confirmed from product data, not estimated.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003ePES7.2T platform fit:\u003c\/strong\u003e\n    The PES7.2T runs a 7.2V rail with a proprietary slide connector. This pack matches that voltage rail and connector pinout. A mismatch in either triggers a no-power condition — this pack avoids that.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this pack through charge and discharge cycles on the PES7.2T platform. The BMS handled motor-start inrush current without tripping on trigger pull, and cell temperature stayed within range under sustained rotary load.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBreak-in protocol for this tool:\u003c\/strong\u003e\n    On first use, run the drill at half load for two cycles before full-torque applications. This allows the BMS to profile the motor's inrush current draw and set overcurrent thresholds accurately before heavy use begins.\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 the PES7.2T during motor-start inrush surge\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eWhen you pull the trigger on the PES7.2T, the motor draws a sharp current spike before it reaches running speed. On a new or cold pack, the BMS may read that spike as an overcurrent event and cut power before the motor even starts turning. Ni-MH chemistry handles inrush better than Li-ion at low temperatures, but a BMS that hasn't yet profiled the motor load will still trip conservatively. Running two break-in cycles at half load teaches the BMS where normal inrush sits, so it stops interrupting on full-trigger pulls.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCharger not recognising the new BS2E7.2T pack after storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNi-MH cells that sit discharged for extended periods can drop below the voltage threshold the charger uses to confirm a valid pack is connected. The charger sees a voltage too low to distinguish a real pack from a short, so it refuses to begin charging. Place the pack in the charger and watch for any response — even a brief blink — within the first two minutes. If there's no response at all, try a different Atlas Copco-compatible charger that supports a trickle pre-charge mode to recover cells sitting below 0.9V per cell.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43416064098394,"sku":"BWCS-MKE720PX-1","price":65.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43416064131162,"sku":"BWCS-MKE720PX-2","price":75.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43416064163930,"sku":"BWCS-MKE720PX-3","price":83.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-MKE720PX-1.webp?v=1779760040","url":"https:\/\/batteryweb.com\/products\/atlas-copco-pes72t-replacement-battery-72v-3300mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
