It replaces OEM part numbers KNB-14, KNB-14A, KNB-14N, KNB-15, KNB-15A, KNB-15H, KNB-20, KNB-20N, and KNB-21. Dimensions match the original pack at 110.68 × 60.88 × 20.91mm.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eCP-213 and ProTalk TK-2200 platform fit:\u003c\/strong\u003e\n    These models share the same 7.2V voltage rail, battery bay dimensions, and contact pin layout. Any pack in the KNB-14 family slots directly into the same bay without modification — the radio's BMS handshake reads cell chemistry and voltage on insertion.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this pack through a full charge-discharge cycle on a KSC-15 dock. The BMS accepted the cell voltage on first insertion, the dock LED moved to charge, and the pack held voltage within spec across sustained PTT load.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eNi-MH conditioning on the KSC-15 dock:\u003c\/strong\u003e\n    Kenwood's KSC-15 and KSC-16 chargers include a conditioning mode — if the battery has sat unused for several months, initiate one full conditioning cycle before field use. Skipping this step with a storage-voltage Ni-MH pack can cause the radio to read one fewer bar than the actual charge state.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the CP-213 cuts out mid-transmission on a fresh Ni-MH pack\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNi-MH cells at storage voltage deliver lower instantaneous current than a fully conditioned pack. When PTT is pressed, transmit current spikes sharply — typically above 1.5A on the TK-2200 platform. If the cell hasn't completed a full charge cycle, that spike can drag cell voltage below the BMS cutoff threshold, causing the radio to cut audio mid-transmission. The fix is a complete charge cycle on the dock before first use, not a partial top-up. A fully charged pack sustains the TX current spike without tripping the cutoff.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eDock shows fault LED after inserting the new pack\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the gold contact strip on the battery or dock terminals has surface contamination that interrupts the BMS handshake signal. The charger interprets a broken handshake as a faulty or incompatible pack and throws the fault LED. Remove the battery, wipe the gold contacts on both the pack and the dock with a dry cloth, then reseat firmly. If the LED still doesn't switch to charge, check that cell voltage is above 5.0V — a pack stored for an extended period may have dropped below the dock's acceptance threshold and needs a recovery charge first.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43426356559962,"sku":"BWCS-KNB140TW-1","price":46.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43426356592730,"sku":"BWCS-KNB140TW-2","price":54.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43426356625498,"sku":"BWCS-KNB140TW-3","price":60.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-KNB140TW-1.webp?v=1779930808","url":"https:\/\/batteryweb.com\/products\/kenwood-cp-213-replacement-battery-72v-2000mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
