It fits the original battery housing and connector without modification. Capacity is 1500mAh (14.4Wh), matching the stock specification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eCTH962K and HP961 platform fit:\u003c\/strong\u003e\n    These models share the same 9.6V battery rail, connector pinout, and housing latch. One battery covers the full compatible range listed — no adapter needed.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this pack through full charge and discharge cycles on a CTH962K chassis. The BMS held cutoff voltage correctly and the charger completed charge without fault codes.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eNi-MH storage precaution:\u003c\/strong\u003e\n    Unlike lithium packs, Ni-MH cells self-discharge at roughly 1–2% per day at room temperature. If the trimmer sits unused for more than three weeks, put the battery on charge before the next session — a fully depleted Ni-MH pack left flat for extended periods can develop cell reversal that permanently reduces capacity.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the CTH962K blade stops mid-cut on dense hedging\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eDense or woody stems force the dual-action blade to stall momentarily, which spikes current draw well above the normal cutting load. Ni-MH cells at 9.6V have limited headroom for sustained high-current bursts — internal resistance rises as the pack depletes, and voltage sags enough to trigger the tool's undervoltage cutoff. The trimmer stops not because the battery is dead, but because the voltage rail dropped below the motor controller's minimum threshold. Start with fresh, fully charged packs when cutting thicker material.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCharger shows no activity after the battery has been in storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNi-MH chargers for this series check cell voltage before initiating the main charge cycle. If the pack has self-discharged below the charger's acceptance threshold — typically around 0.9V per cell — the charger may show no lights or a fault state. Leave the pack connected for 10–15 minutes; many chargers in this range include a trickle pre-charge that slowly raises the cell voltage to the acceptance window before switching to full charge. If the charger remains unresponsive after 20 minutes, check that the terminal contacts on both the battery and charger are clean and fully seated.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43416079466586,"sku":"BWCS-RTH962PW-1","price":74.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43416079499354,"sku":"BWCS-RTH962PW-2","price":87.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43416079532122,"sku":"BWCS-RTH962PW-3","price":96.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-RTH962PW-1.webp?v=1779760143","url":"https:\/\/batteryweb.com\/products\/ryobi-cth962k-replacement-battery-96v-1500mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
