Both tools run on the same 6V battery platform and share connector and cell format. Swap it in when the original pack no longer holds a charge or cuts out under blade load.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eCHS6000 and CHS6000 Recip-Saw platform:\u003c\/strong\u003e\n    Both models share the same 6V rail, connector pitch, and BMS handshake. One battery covers both tools — no adapter or wiring change 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 blade-load starts on the CHS6000. The BMS held through inrush current spikes on trigger pull and did not trip under sustained trimming loads at rated voltage.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eNi-MH cycling discipline for hedge trimmer use:\u003c\/strong\u003e\n    Ni-MH chemistry suffers from voltage depression when repeatedly charged after short use sessions. Run the pack down through a full trimming session before recharging — partial cycles build up memory effect in Ni-MH cells faster than in lithium chemistry.\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 CHS6000 blade-start inrush\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe CHS6000 blades draw a short inrush spike the moment the trigger fires. On a degraded or deeply discharged Ni-MH pack, internal resistance is high enough that this spike causes a voltage drop the BMS reads as an overcurrent fault. The tool cuts out immediately after trigger pull — not mid-session. A fresh, fully charged pack with low internal resistance handles the inrush without tripping. Charge the new battery to full before first use to ensure cell impedance is at its lowest before the BMS encounters that startup spike.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eTool bogs and slows mid-session under steady trimming load\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eIf the CHS6000 starts strong but loses blade speed after a few minutes of continuous cutting, the cause is voltage sag — not a BMS trip. As the cells discharge, terminal voltage drops under sustained motor current draw, and the tool loses torque before the pack is actually empty. Check the battery contact rails on both the tool and pack for oxidation or debris, since contact resistance makes sag worse. Clean contacts with isopropyl alcohol and confirm resting pack voltage reads at least 6.6V before a session.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43416003936346,"sku":"BWCS-BHC600PW-1","price":43.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43416003969114,"sku":"BWCS-BHC600PW-2","price":51.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43416004001882,"sku":"BWCS-BHC600PW-3","price":56.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-BHC600PW-1.webp?v=1779759244","url":"https:\/\/batteryweb.com\/products\/black-decker-chs6000-replacement-battery-6v-2000mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
