It replaces the original pack when cells have degraded and the tool can no longer hold a working charge. Capacity is 1500mAh (18Wh), matching the original pack specification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eCHT 300, CLT100, CMT200 platform:\u003c\/strong\u003e\n    These three Cyklop models share the same 12V battery platform — same connector format, same voltage rail, and the same BMS handshake protocol. One pack fits all three without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this pack through charge and load cycles on a CHT 300. The BMS responded correctly to inrush current at trigger pull and held the voltage rail stable under sustained drill load without nuisance tripping.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-use break-in for Ni-MH cells:\u003c\/strong\u003e\n    Run the tool at half load for two cycles before applying maximum torque. Ni-MH cells benefit from a conditioning period — this allows the BMS to profile the motor's inrush draw before setting its overcurrent thresholds accurately.\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 with the CHT 300\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eEvery time you pull the trigger on a cordless drill, the motor draws a spike of current far above its steady running load — this is inrush current. On the CHT 300, this spike can reach three to five times the continuous draw for a fraction of a second. A new Ni-MH pack that hasn't been conditioned may have its BMS threshold set conservatively, causing it to interpret that spike as a fault. Two break-in cycles at reduced load teach the BMS what a normal trigger pull looks like, stopping false cutoffs during full-torque applications.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eTool bogs under load and feels underpowered mid-task\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eIf the CHT 300 feels slow or loses torque when driving fasteners, the most likely cause is voltage sag from high contact resistance at the battery terminals. Dirty or corroded contacts between the pack and tool body increase resistance, which drops the rail voltage under load even when the cells are healthy. Clean the battery contacts and the tool's battery bay contacts with isopropyl alcohol and a clean cloth. After cleaning, check that the resting pack voltage reads at least 13.5V on a multimeter — anything lower after a full charge points to a cell issue, not the contacts.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43416085397594,"sku":"BWCS-BS3455PW-1","price":76.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43416085430362,"sku":"BWCS-BS3455PW-2","price":89.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43416085463130,"sku":"BWCS-BS3455PW-3","price":98.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-BS3455PW-1.webp?v=1779760222","url":"https:\/\/batteryweb.com\/products\/cyklop-cht-300-replacement-battery-12v-1500mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
