It replaces the original cell when capacity has dropped to the point the tool bogs under load or won't hold a charge. Dimensions are 45.30 × 35.20 × 22.80mm — confirm these against your existing pack before ordering.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003e9073 and 9073 Type 1 fitment:\u003c\/strong\u003e\n    Both variants run the same 2.4V rail and use the same connector housing and cell format. A single replacement cell pack covers both, because the Type 1 designation reflects a production revision, not an electrical change.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through repeated trigger-pull loads on the 9073 platform. The Ni-MH cells absorbed motor-start inrush without tripping the protection circuit, and voltage recovery after load release was consistent across the first five cycles.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBreak-in on the 9073:\u003c\/strong\u003e\n    Run the drill at half load for the first two cycles before applying full torque. Ni-MH cells at low voltage need shallow discharge-charge passes to balance internal resistance across all cells before heavy drilling sessions.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eVoltage sag on the 9073 under sustained fastening load\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe 9073 runs at 2.4V — a single two-cell Ni-MH configuration with very little voltage headroom. Under sustained fastening loads, internal cell resistance causes the rail to sag below the motor's effective operating voltage faster than on higher-voltage packs. This shows up as the tool slowing mid-screw or losing torque on the second or third fastener in a row. Fresh cells with lower internal resistance recover the rail; aged or deeply discharged cells do not. If sag is happening on a new pack, check contact resistance at the battery terminals first — even slight oxidation at 2.4V is enough to drop the effective voltage to the motor.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCharger not recognising the new pack after storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNi-MH packs that sit in storage self-discharge over time, and if the cell voltage drops below the charger's acceptance threshold, the charger won't initiate a charge cycle. On the 9073 platform this appears as no indicator light or an immediate fault signal when the pack is seated. A brief trickle charge — if your charger supports it — or a short discharge-then-charge cycle using the tool itself for a few seconds can bring the cell voltage up enough for the charger to register it. Target cell voltage above 1.0V per cell (2.0V pack total) before attempting a standard charge cycle.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43416005541978,"sku":"BWCS-BKS907PW-1","price":39.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43416005574746,"sku":"BWCS-BKS907PW-2","price":46.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43416005607514,"sku":"BWCS-BKS907PW-3","price":51.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-BKS907PW-1.webp?v=1779759245","url":"https:\/\/batteryweb.com\/products\/black-decker-9073-replacement-battery-24v-2000mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
