It slots into the handset battery compartment and restores wireless operation when the original cell no longer holds a usable charge. Dimensions are 50.36 × 28.11 × 14.33mm — confirm against your existing pack before ordering.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eCS6128 and CS6129 compatibility:\u003c\/strong\u003e\n    Both models run the same 2.4V two-cell NiMH pack on a shared handset platform. Voltage rail, connector pinout, and compartment dimensions are identical across this pair, so one replacement covers both.\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 the CS6128 handset. The base station accepted the battery without error and the BMS reached full charge termination cleanly on each cycle.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-charge protocol for NiMH handsets:\u003c\/strong\u003e\n    After installing, seat the handset in the base and leave it untouched for a full 16 hours before the first call. NiMH cells ship partially discharged — skipping this slow initial charge limits capacity and the battery will never reach its rated 1200mAh.\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\n  \u003cp class=\"bpw-desc-p\"\u003eNiMH cells need three to five full charge-discharge cycles to reach rated capacity — this is normal chemistry, not a fault. A fresh pack pulled from storage has a depressed charge ceiling that lifts gradually with each full cycle. Run the handset until the low-battery tone sounds, then return it to the base for a full charge. By cycle five, capacity should be at or near the rated 1200mAh.\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\"\u003eNiMH packs discharged below roughly 0.9V per cell during storage can fall outside the voltage window the base uses to detect a valid battery. The base charges only when it sees a minimum input voltage — if the pack is too flat, charging never starts. Remove the handset, wait 10 seconds, then reseat it firmly. If the light still does not activate, use a compatible external NiMH charger to bring the pack above 2.0V total, then return it to the base cradle.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43339995643994,"sku":"BWCS-BPT50CL-1","price":12.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43339995676762,"sku":"BWCS-BPT50CL-2","price":13.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43339995709530,"sku":"BWCS-BPT50CL-3","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-BPT50CL-1.webp?v=1778367024","url":"https:\/\/batteryweb.com\/products\/v-tech-cs6128-replacement-battery-24v-1200mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
