It matches the OEM part CIW32ZBR and fits directly into the battery compartment of both models. Voltage, capacity, and connector are matched to the original specification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eWIP300 and WIP320 compatibility:\u003c\/strong\u003e\n    Both handsets run off the same 3.7V cell with the same connector footprint and BMS handshake. One battery covers both models without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through charge and discharge on the WIP300 platform. The BMS accepted full charge without fault flags, and voltage held steady across the RF transmit load during active calls.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-charge protocol for Li-ion cordless handsets:\u003c\/strong\u003e\n    After installing, seat the handset in the base cradle and leave it for a full uninterrupted charge cycle before first use. The WIP300 base charger uses a trickle-top-up method — cutting the charge short on the first cycle can result in the BMS logging a lower full-charge threshold than the cell is actually rated for.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the WIP300 base station shows no charge indicator on a new battery\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eA Li-ion cell shipped from storage often sits at 3.4V or lower. The WIP300 base charger checks cell voltage before starting the charge circuit — if the voltage reads below its acceptance threshold, the charge indicator stays dark. This is not a fault with the battery or the base. Place the handset in the cradle and leave it for 15–20 minutes; the charger's pre-charge stage will bring the cell up to the 3.6V threshold, after which the normal charge indicator will activate.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eTalk time noticeably shorter than the original battery after replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eA new Li-ion cell does not always deliver full rated capacity on the first cycle. The internal chemistry needs two to three full charge-discharge cycles before the cell reaches its rated 1000mAh output. If talk time still feels short after three full cycles, check that the handset is fully seated in the base between calls — a poor cradle contact causes incomplete charges that compound over time. After conditioning, a fully charged cell should hold voltage above 3.6V at rest.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43339920572506,"sku":"BWCS-CIP320CL-1","price":22.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43339920605274,"sku":"BWCS-CIP320CL-2","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43339920638042,"sku":"BWCS-CIP320CL-3","price":27.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-CIP320CL-1.webp?v=1778366983","url":"https:\/\/batteryweb.com\/products\/cisco-linksys-wip300-replacement-battery-37v-1000mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
