It also fits the BHR261RDE, MUB360DZ, and MUH550DZ. Use the OEM part numbers BL3626, 194874-0, or BL3622A to confirm compatibility with your existing pack.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eBHR261 and MU-series compatibility:\u003c\/strong\u003e\n    These models share the same 36V battery rail, slide-in connector, and BMS handshake protocol. The same pack slides into the rotary hammer and the hedge trimmer or brushcutter variants without adaptation.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this pack through repeated motor-start trigger cycles on a BHR261. The BMS handled inrush current correctly on each pull, held the voltage rail steady through sustained concrete drilling, and tripped thermal cutoff only when cell temperature reached the expected threshold.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBreak-in on first use:\u003c\/strong\u003e\n    On first use, run the drill at half load — light concrete or masonry — for two full cycles before pushing maximum torque. This lets the BMS profile the motor's inrush draw and calibrate overcurrent thresholds before heavy-duty chiseling.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBMS overcurrent trip on motor-start inrush in the BHR261\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eRotary hammer drills draw a sharp current spike the moment you pull the trigger — particularly in hammer mode. If the BMS hasn't profiled the motor yet, that inrush can exceed the default overcurrent threshold and trip the pack before the bit starts turning. A freshly installed replacement pack is most vulnerable on the first few pulls. Running two break-in cycles at reduced load lets the BMS log the inrush pattern and raise its threshold accordingly.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCharger shows blinking red on a new BL3626 pack after storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-ion cells discharged below roughly 2.5V per cell will be rejected by most Makita chargers as a safety measure. A pack that sat in storage can drop below charger acceptance voltage. To recover it, check cell voltage with a multimeter — if the pack reads below 30V total, try a compatible charger with a recovery or wake-up mode. Once cells are back above the acceptance floor, the charger will recognise the pack and begin the normal charge cycle.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43416055382106,"sku":"BWCS-MKT261PW-1","price":155.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43416055414874,"sku":"BWCS-MKT261PW-2","price":184.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43416055447642,"sku":"BWCS-MKT261PW-3","price":205.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-MKT261PW-1.webp?v=1779759859","url":"https:\/\/batteryweb.com\/products\/makita-bhr261-replacement-battery-36v-3000mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
