In a business environment where remote collaboration is part of daily operations, the communication equipment powering your conference rooms, huddle spaces, and executive offices needs to be reliable without exception. A weak or failing battery in any piece of that setup introduces exactly the kind of unreliability that erodes confidence in a meeting before a single agenda item gets covered.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eWe carry replacement batteries for the full range of professional communication and conferencing equipment used in modern business environments — Polycom speakerphones, Jabra wireless conference units, Plantronics headsets, Konftel conference phones, Logitech collaboration devices, and the portable Bluetooth conference speakers that travel with professionals from office to client site and back again. Whether you are running a dedicated Teams room or Zoom room setup that needs to perform flawlessly every single day, managing a fleet of wireless headsets across a contact center, or simply keeping a portable conference speaker charged and ready for meetings on the go, finding the right replacement battery here keeps every piece of your communication stack performing at the level your business depends on. Browse by brand or device model, get the right battery in place, and make sure the next time someone dials in, your room sounds as professional as the work happening inside it.\u003c\/p\u003e","products":[{"product_id":"yamaha-rm-wgl-replacement-battery-37v-1800mah-li-polymer","title":"Yamaha RRC1120 Wireless Microphone Replacement Battery 3.7V 1800mAh","description":"\u003cdiv class=\"bpw-desc\"\u003e\n  \u003ch2 class=\"bpw-desc-h2\"\u003eYamaha RM-WGL \/ RM-WGS — 3.7V Li-Polymer Replacement Battery (RRC1120)\u003c\/h2\u003e\n\n  \u003cp class=\"bpw-desc-lead\"\u003eThis 3.7V 1800mAh (6.66Wh) lithium-polymer battery replaces the original pack in Yamaha RM-WGL and RM-WGS wireless directional tabletop microphone units.

When a new pack goes in, the unit has no charge history for those cells, so the threshold mapping starts from zero. The indicator can show full, empty, or a static mid-level until the system observes a complete charge-to-discharge cycle. One full charge followed by normal use resets the mapping and brings the display in line with actual cell state.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWireless connection dropping mid-meeting after battery replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eIf the Conference Max Plus loses its wireless link partway through a session, voltage sag under combined audio processing and wireless transmitter draw is usually the cause. Ni-MH cells that have not yet been conditioned show a sharper voltage dip under this dual load than a fully cycled pack. The unit's RF module is sensitive to voltage floor — if the pack dips below its operating threshold, the wireless link drops before the unit fully powers off. Charge the pack to 100% before the session and run one full cycle to condition the cells.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43339864277082,"sku":"BWCS-CMW592SL-1","price":33.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43339864309850,"sku":"BWCS-CMW592SL-2","price":38.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43339864342618,"sku":"BWCS-CMW592SL-3","price":42.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-CMW592SL-1.webp?v=1778366843"},{"product_id":"clearone-max-replacement-battery-72v-2000mah-ni-mh","title":"ClearOne Max 7.2V Ni-MH Replacement Battery 220AAH6SMLZ","description":"\u003cdiv class=\"bpw-desc\"\u003e\n  \u003ch2 class=\"bpw-desc-h2\"\u003eClearOne Max \/ Max Wireless — 7.2V Ni-MH Replacement Battery (220AAH6SMLZ)\u003c\/h2\u003e\n\n  \u003cp class=\"bpw-desc-lead\"\u003eThis is a 7.2V, 2000mAh Ni-MH replacement battery for ClearOne Max and Max Wireless conferencing systems.

The Max series maps battery state against voltage thresholds during normal operation. A fresh pack that hasn't completed one full cycle may display inaccurate charge warnings for the first session — this corrects itself after that initial cycle.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWireless connection drops under combined audio and transmitter draw\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe Max Wireless unit runs both an audio processing circuit and a wireless transmitter from the same 7.2V cell stack. When the pack is aged or stored for months before installation, internal resistance climbs. Under that combined load, voltage sags briefly below the radio module's operating threshold — enough for the wireless link to drop even though the unit still appears powered. This is different from a dead battery; the unit looks fine at rest but cuts out during active use. Fitting a new pack with low internal resistance eliminates the sag, and the connection holds through the full session.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCharging dock not recognising a freshly installed pack\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eIf the dock LED doesn't change state after seating the unit, the most common cause is contact resistance between the battery terminals and the dock's charge pins — not a faulty pack. Storage dust and oxidation on the gold contacts can block the low-current sense signal the dock uses before it begins charging. Remove the unit, wipe the battery contacts and dock pins with a dry cloth, then reseat firmly. If the dock still doesn't respond, check that pack voltage is above 5.0V with a multimeter — a pack that dropped below that threshold during storage may need a conditioning charge before the dock will accept it.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43339864375386,"sku":"BWCS-CMW592SL-1","price":33.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43339864408154,"sku":"BWCS-CMW592SL-2","price":38.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43339864440922,"sku":"BWCS-CMW592SL-3","price":42.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-CMW592SL-1.webp?v=1778366843"}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/collections\/BW-CS-HMS330CL-6.webp?v=1780884723","url":"https:\/\/batteryweb.com\/collections\/communication-conferencing.oembed?page=2","provider":"BatteryWeb","version":"1.0","type":"link"}
