It fits the T7400, T7500, and T7800 series. Install it when the original pack no longer holds a charge and the handset dies quickly off the base.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eT7400, T7500, and T7800 compatibility:\u003c\/strong\u003e\n    All three models share the same handset PCB layout, 3.6V charging rail, and three-cell AAA Ni-MH pack format. The connector pinout and physical dimensions are identical across the series — no modification needed.\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 T7400 handset. The base station accepted the battery without error, the charge indicator activated normally, and the BMS held voltage within the expected Ni-MH window throughout.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst charge on a Ni-MH cordless handset:\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 cells shipped in partial charge state need this slow initial charge to reach rated capacity — skipping it shortens talk time for the first several cycles.\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 full rated capacity straight out of the box. The electrochemical structure needs three to five full charge and discharge cycles before capacity stabilises at 700mAh. If talk time seems short in the first few days, that's the conditioning process — not a fault with the cell. Run the handset to low battery on the base, then charge fully each time, and capacity will increase with each cycle.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBase station charge light not activating after battery swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNi-MH batteries stored before sale can drop below the threshold the base station expects to see before starting a charge cycle. If the charge light stays off or shows an error, remove the handset, hold the power button for five seconds to fully discharge any residual voltage, then re-seat it in the base. This prompts the base to re-detect the pack. If the light still doesn't activate, check the handset contacts and base cradle pins are clean and making firm contact.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43340003410010,"sku":"BWCS-SPR5060CL-1","price":22.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43340003442778,"sku":"BWCS-SPR5060CL-2","price":24.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43340003475546,"sku":"BWCS-SPR5060CL-3","price":26.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-SPR5060CL-1.webp?v=1778367047","url":"https:\/\/batteryweb.com\/products\/thomson-t7400-replacement-battery-36v-700mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
