It fits the 1050D, 1050DA, 1050DRA, 1050DWA, and over 147 other Makita 12V platform tools. The connector, latch geometry, and cell voltage match the original pack specification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003e12V Makita platform fit:\u003c\/strong\u003e\n    The 1050D series shares its battery slot with a wide range of Makita 12V tools — same three-post connector, same latch release, same BMS handshake protocol. Any tool accepting part numbers 1220, 1222, or 192598-2 will accept this pack without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack on a 1050D under repeated trigger-pull loads. The BMS handled motor-start inrush without tripping, and cell temperature stayed within spec through ten consecutive charge-discharge cycles.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBreak-in on the 1050D:\u003c\/strong\u003e\n    On first use, run the drill at half load — light driving, no high-torque fastening — for two full discharge and charge cycles. This lets the BMS establish accurate overcurrent thresholds for the motor's inrush profile before you push it to maximum torque.\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 1050D motor-start inrush surge\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eEvery trigger pull on a cordless drill sends a current spike into the motor before it reaches running speed. On a 12V Ni-MH pack, that inrush spike can briefly hit three to four times the steady-state draw. If the BMS overcurrent threshold is set conservatively — common on new or freshly restored packs — it will cut the circuit the instant you pull the trigger. Running two break-in cycles at low torque trains the BMS to the actual inrush profile of the 1050D motor and stops nuisance trips under normal use.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eMakita charger flashing red and refusing to accept the new pack\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eMakita 12V chargers check cell voltage before entering charge mode. If the pack has sat in a warehouse below the charger's acceptance threshold — typically around 1V per cell — the charger signals a fault instead of charging. To recover, place the pack in the charger and leave it for 15 minutes without removing it; some Makita chargers include a trickle pre-charge stage that activates automatically once the handshake times out. If the light stays red after 20 minutes, check that the terminal contacts are clean and making firm contact — oxidised posts will read as a dead cell to the charger. A clean contact and a second attempt usually brings the pack into normal charge mode.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43416084578394,"sku":"BWCS-MKT105HW-1","price":90.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43416084611162,"sku":"BWCS-MKT105HW-2","price":106.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43416084643930,"sku":"BWCS-MKT105HW-3","price":117.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-MKT105HW-1.webp?v=1779760241","url":"https:\/\/batteryweb.com\/products\/makita-1050d-replacement-battery-12v-3000mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
