It fits the Skil 2587 and 2587-05 cordless drill\/driver. Swap it in when the original pack no longer holds a charge or refuses to accept a charge cycle.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003e2587 and 2587-05 platform fit:\u003c\/strong\u003e\n    Both model variants run the same 14.4V rail and use the same slide-in battery contact geometry and latch mechanism, so one pack covers both. No adapter or modification needed.\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 events on a 2587 body and monitored the BMS response to inrush current spikes. The overcurrent threshold held without nuisance trips across full discharge cycles.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eHalf-load break-in on first use:\u003c\/strong\u003e\n    On the first two cycles, run the drill at medium torque settings — not full torque into hard materials. This lets the BMS log the motor's inrush current signature before it sets its overcurrent protection thresholds. Skipping this step on Ni-MH packs can cause early cutoffs under sudden load.\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 motor-start inrush during hard drilling applications\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eWhen you drive a large bit into dense material, the 2587's motor pulls a short but sharp inrush current spike at trigger pull. On a new or cold Ni-MH pack, the BMS may interpret that spike as an overcurrent event and cut power before the motor reaches speed. This is not a faulty pack — it is the protection circuit doing its job with incomplete data. Running two break-in cycles at half load trains the BMS to distinguish normal inrush from a genuine fault. After break-in, full-torque applications should proceed without nuisance trips.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCharger not recognising the new pack after storage\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eNi-MH packs lose voltage during storage, and if a cell group drops below the charger's acceptance threshold — typically around 0.9V per cell — the charger refuses to initiate a charge cycle and may blink an error. This does not mean the pack is dead. Place the battery in a warm environment (18–25°C) for 30 minutes, then retry the charger. If the charger still does not engage, a brief trickle charge using a compatible Ni-MH trickle charger can bring cell voltage up to 1.0V per cell, at which point the main charger will recognise the pack and begin a normal cycle.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43416061116506,"sku":"BWCS-SHD587PW-1","price":86.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43416061149274,"sku":"BWCS-SHD587PW-2","price":101.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43416061182042,"sku":"BWCS-SHD587PW-3","price":112.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-SHD587PW-1.webp?v=1779760056","url":"https:\/\/batteryweb.com\/products\/skil-2587-replacement-battery-144v-2100mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
