It fits the Talkman A500, T5, and Talkman T5 models used in warehouse pick-and-pack and inventory operations. OEM part numbers covered: 730022, 136020805B, 730040, and BT700.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eA500 and T5 platform fit:\u003c\/strong\u003e\n    Both the A500 and T5 share the same battery bay geometry, connector pin-out, and BMS handshake protocol — one cell covers both units without any modification or adapter.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through repeated scan-trigger and wireless polling loads. The BMS held voltage within spec across burst events and did not trip on the combined radio-plus-imager draw.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-shift preparation on the Talkman:\u003c\/strong\u003e\n    After installing the pack, seat the Talkman in its cradle and run a full charge cycle before starting a pick shift. The scan trigger inrush is highest when the cell sits near minimum charge, and a fully charged cell prevents false BMS cutoffs on the first burst of the day.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the Talkman A500 drops wireless mid-shift during heavy scan bursts\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe A500 fires the imager and the 802.11 radio almost simultaneously during active picking. Each event draws a short current spike, and back-to-back bursts stack those spikes without recovery time. On a degraded or partially charged cell, this combined draw pulls the pack voltage below the BMS low-voltage threshold, triggering a momentary cutoff. The radio drops first because the wireless subsystem is the first load shed when the BMS protects the cell — the imager stays active a fraction longer before the unit resets.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCradle showing a charging error after fitting a new pack\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eA charging error on a new pack is almost always a contact resistance issue at the dock, not a fault with the battery itself. Dust and oxidation on the cradle's charging pins or the battery's contact pads raise resistance enough that the dock's charge controller reads an incomplete circuit. Wipe the battery contacts and the cradle pins with a dry cloth, reseat the pack firmly, and check that the Talkman clicks fully into the dock. If the error clears, the pack was not fully seated; if it persists, check the cradle pins for physical damage or corrosion.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43324712222810,"sku":"BWCS-VTM500BX-1","price":77.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43324712255578,"sku":"BWCS-VTM500BX-2","price":91.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43324712288346,"sku":"BWCS-VTM500BX-3","price":100.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-VTM500BX-1.webp?v=1778122647","url":"https:\/\/batteryweb.com\/products\/vocollect-talkman-a500-replacement-battery-37v-5200mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
