It also fits the KX-T1232, KX-T308, and KX-T123210, along with ten additional models in the same series. Install it when the original pack no longer holds a charge and the handset dies mid-call or won't leave the base.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eKX-T308 series compatibility:\u003c\/strong\u003e\n    These models share a 2.4V two-cell Ni-MH pack with the same footprint and connector orientation. The base station charges at a trickle rate matched to this chemistry — swapping in a different voltage or chemistry will confuse the charge circuit.\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 discharge cycles on the KX-A16 handset. The BMS accepted charge immediately from the base station, and the handset registered full signal strength through each cycle without voltage sag cutting the RF output.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst charge on KX-series handsets:\u003c\/strong\u003e\n    After installing, seat the handset in the base and leave it for a full 16 hours before first use. Ni-MH packs in KX-series phones arrive partially discharged from storage — a slow first charge lets the cells reach rated capacity. Skipping this step means the first few talk sessions will be noticeably shorter than expected.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eTalk time shorter than the original battery after replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNi-MH cells don't deliver rated capacity on the first cycle — they need three to five full charge-discharge cycles to reach the 300mAh spec. If talk time feels short after the first day, this is normal. Run the handset until it signals low battery, return it to the base for a full 16-hour charge, and repeat. By cycle five, capacity should match or beat the original worn pack.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBase station shows no charge or error light after new pack is installed\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNi-MH packs stored in a warehouse can drop below the voltage threshold the KX-series base station expects before it starts a charge cycle. If the base light stays off or flashes an error, the pack voltage is too low for the base to accept. Briefly connect the handset to a USB charger set to 5V for 30 seconds to nudge the cell voltage up, then seat it back in the base — the charge indicator should engage normally after that.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43340077138010,"sku":"BWCS-T308CL-1","price":22.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43340077170778,"sku":"BWCS-T308CL-2","price":24.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43340077203546,"sku":"BWCS-T308CL-3","price":26.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-T308CL-1.webp?v=1778367047","url":"https:\/\/batteryweb.com\/products\/panasonic-kx-a16-replacement-battery-24v-300mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
