It replaces OEM part numbers BP60 and BP72. The pack slots into the original battery bay and communicates with the tool's onboard charge management system.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eTE 5 A, C 7\/24, C 7\/36, and TCU 7\/36 compatibility:\u003c\/strong\u003e\n    All four models share the same 24V battery architecture, connector pinout, and BMS handshake protocol — one pack covers the full platform without modification or adapters.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through repeated high-torque trigger pulls on the TE 5 A and monitored the BMS response under inrush current spikes. The overcurrent protection threshold held at the expected cut-off without nuisance trips under normal drilling loads.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eNi-MH conditioning on first use:\u003c\/strong\u003e\n    On first use, run the tool at half load for two full cycles before hitting maximum torque applications — this allows the BMS to profile motor inrush current draw and set accurate overcurrent protection thresholds before sustained hammer use.\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 TE 5 A motor-start inrush surge\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe TE 5 A rotary hammer pulls a sharp inrush current spike the instant the trigger is pulled — especially when starting under load in concrete. If the BMS has not profiled the motor draw, it can misread this spike as an overcurrent fault and shut the pack down. A new or recently stored pack is most vulnerable because the BMS fault threshold defaults to a conservative setting until it logs actual load cycles. Running two break-in cycles at reduced load before full hammer work lets the BMS calibrate correctly and prevents premature trips.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003ePack drops off mid-use but charger shows full after a short rest\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is voltage sag — not a failed pack. Under sustained hammer load, internal cell resistance causes the pack's rail voltage to sag below the tool's low-voltage cutoff, triggering a shutdown. After a short rest, voltage recovers and the charger reads the pack as acceptable. Check the battery bay contacts first — oxidised or dirty contact pins increase resistance and worsen sag. If contacts are clean, the cells may have degraded from repeated shallow cycling; a full discharge-to-cutoff followed by a complete charge cycle can partially restore usable capacity.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43416032804954,"sku":"BWCS-HBP720PX-1","price":146.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43416032837722,"sku":"BWCS-HBP720PX-2","price":173.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43416032870490,"sku":"BWCS-HBP720PX-3","price":193.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-HBP720PX-1.webp?v=1779759610","url":"https:\/\/batteryweb.com\/products\/hilti-te-5-a-replacement-battery-24v-3300mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
