It replaces the original handset battery when the existing cell no longer holds a useful charge. Dimensions are 50.43 × 42.54 × 14.40mm — measure your existing pack before ordering if you are unsure.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003ePC3310, PC3320, PC3330 compatibility:\u003c\/strong\u003e\n    These three ITT handsets share the same battery bay dimensions, connector orientation, and nominal 3.6V supply rail, which is why a single cell fits all three. The base charging circuit in each model expects the same charge acceptance curve from a Ni-MH pack.\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 to confirm the cell accepts a trickle charge without tripping the base unit's error state, and that voltage holds above 3.4V under handset RF transmit load.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst charge on ITT DECT 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 cells shipped in storage-state charge up unevenly on a fast cycle — the slow first charge lets each cell in the pack reach balanced capacity.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy ITT PC3310 handsets show reduced range after a battery swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eDECT transmitters in handsets like the PC3310 draw a burst of current during each RF pulse. If the replacement Ni-MH pack hasn't been through two or three full conditioning cycles, its internal resistance is still high. That resistance causes voltage to sag during each transmit burst, which the handset's RF circuit reads as low power — it reduces transmit strength to compensate. After three to five full charge and discharge cycles, internal resistance drops and voltage sag narrows, restoring normal transmit behaviour.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBase station shows no charge light on a freshly installed Ni-MH pack\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eITT base units detect a new battery by measuring resting voltage before starting the charge cycle. A Ni-MH cell that has sat in storage can drop to 3.0V or below, which falls outside the base unit's acceptance window — the charger stays off and no light triggers. To recover, apply a brief external charge using a standalone Ni-MH charger until the pack reads at least 3.3V, then seat the handset in the base. The base unit should recognise the pack and begin the standard charge cycle from that point.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43340029460570,"sku":"BWCS-P502CL-1","price":23.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43340029493338,"sku":"BWCS-P502CL-2","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43340029526106,"sku":"BWCS-P502CL-3","price":28.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-P502CL_1.webp?v=1778367047","url":"https:\/\/batteryweb.com\/products\/itt-pc3310-replacement-battery-36v-1200mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
