It replaces OEM part numbers HHR-P103, HHR-P103A, N4HHGMB00001, N4HHGMB00005, and N4HHGMN00001. Dimensions are 47.00 × 32.00 × 11.50mm — check yours before ordering if the compartment is tight.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eKX-TGA271 and KX-TGA272 handset family:\u003c\/strong\u003e\n    These models share the same 3.6V single-cell Ni-MH battery bay, physical clip connector, and base-station charge circuit. One battery part number covers the full range, including the KX-TGA271A, KX-TGA271W, KX-TGA272, and KX-TGA272S variants.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through charge and discharge on a Ni-MH compatible test rig, confirming the cell holds voltage within spec across the full discharge curve. The base station handshake completed normally — no charge-error light triggered.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-charge protocol for Ni-MH cordless handsets:\u003c\/strong\u003e\n    After installing, seat the handset in the base and leave it for a full 16 hours before the first call. Ni-MH cells in cordless phones arrive partially discharged from storage. Skipping the slow first charge is the leading cause of short talk time complaints in the first week of use.\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 rated after battery swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNi-MH cells do not reach full rated capacity on the first cycle. Fresh cells typically deliver 60–75% of rated capacity on cycle one, stepping up with each full charge and discharge. The KX-TGA271 base station delivers a trickle charge once the handset is seated — it does not fast-charge. Allow three to five full cycles before judging capacity. After cycle five, a healthy pack holds 3.6V through most of the discharge curve.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBase station charge light stays red or shows error after new battery installed\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eA Ni-MH pack stored in a warehouse can drop below the voltage floor the Panasonic base station accepts before starting a charge cycle. The base reads the pack as faulty and stops charging. Remove the handset, wait 30 seconds, then reseat it firmly — the base will retry the charge-start handshake. If the error persists, check that the handset contacts and base cradle contacts are clean and making full metal-to-metal contact; a film of oxidation on either contact blocks the circuit.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43340104990810,"sku":"BWCS-CPB9034-1","price":22.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43340105023578,"sku":"BWCS-CPB9034-2","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43340105056346,"sku":"BWCS-CPB9034-3","price":27.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-CPB9034-1.webp?v=1778367187","url":"https:\/\/batteryweb.com\/products\/panasonic-kx-tga271a-replacement-battery-36v-700mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
