These compact screwdrivers are common on fastening and light drilling work where a small, handheld form factor matters. Slot this pack in when the original cell block can no longer hold a working charge.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003e6722DW, 6723DW, and 6722D compatibility:\u003c\/strong\u003e\n    All three models run the same 4.8V rail with an identical battery housing and contact layout. The cell block dimensions — 50.86 × 28.96 × 28.96mm — match the original cavity without modification. No adapter, no rewiring.\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 load sequences on a 6722D. The Ni-MH cells recovered voltage quickly between bursts, and the internal protection circuit held steady across motor-start inrush without tripping.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBreak-in procedure for Ni-MH cells:\u003c\/strong\u003e\n    Run two full discharge-and-charge cycles at light fastening load before using the screwdriver at maximum torque. Ni-MH cells need conditioning cycles to reach rated capacity — skipping this leaves measurable capacity on the table in early use.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the 6722DW stalls or cuts out on trigger pull\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eAt trigger pull, a cordless screwdriver draws a short inrush spike — often three to five times the running current — before the motor reaches speed. On a degraded or deeply discharged Ni-MH pack, internal resistance is high enough that this spike collapses the cell voltage below the protection circuit's cutoff threshold. The tool stops instantly, even though the battery showed a charge. A fresh, fully conditioned pack keeps internal resistance low and handles that inrush without a voltage drop that triggers the cutoff.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCharger light stays red and never switches to green on a new pack\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eMakita's original chargers for this voltage range use a delta-peak detection method — they look for a small voltage drop that signals the cells are full. If a new Ni-MH pack has sat in storage, cell voltage can drift low enough that the charger won't begin a standard charge cycle. To recover it, place the battery in the charger and leave it for 30 minutes; some chargers apply a trickle pre-charge to bring the pack above the acceptance threshold before switching to full charge. If the light stays red beyond that, check the pack contacts are clean and seated — corrosion on the terminal strip is a common cause. A correctly seating pack at 4.8V nominal should trigger charge acceptance within a few minutes.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43416050860122,"sku":"BWCS-MKT672PW-1","price":31.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43416050892890,"sku":"BWCS-MKT672PW-2","price":36.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43416050925658,"sku":"BWCS-MKT672PW-3","price":39.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-MKT672PW-1.webp?v=1779759860","url":"https:\/\/batteryweb.com\/products\/makita-6722dw-replacement-battery-48v-2000mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
