It fits the compact palm-form-factor device used in retail, warehouse, and field data collection workflows. Voltage and capacity match OEM spec exactly — 3.7V, 3350mAh (12.4Wh).\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003ePS20 and PS20J compatibility:\u003c\/strong\u003e\n    Both models share the same battery bay geometry, connector pinout, and BMS handshake protocol. One cell fits either unit — no hardware modification required.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through scan-burst and wireless-transmission loads on the PS20 platform. The BMS held voltage regulation steady across combined radio and imager draw without tripping prematurely.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-shift preparation:\u003c\/strong\u003e\n    After installing, seat the scanner in its cradle for a full charge cycle before picking up a shift. Scan trigger inrush current peaks when the cell is near minimum — a fully charged pack prevents false BMS trips on the opening scans of a shift.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCradle charging error on a new PS20 battery pack\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe PS20 cradle reads pack state through spring-loaded dock contacts on the battery base. Oxidation or shipping residue on those contacts raises resistance enough for the dock to report a charging fault before the charge cycle even starts. Wipe the gold contacts on both the battery and cradle insert with a dry cloth, then reseat the scanner firmly until the dock LED changes state. If the error clears, the cell was never the problem — contact resistance was.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eScanner losing wireless connection during rapid scan bursts\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eDuring a rapid scan sequence, the PS20 pulls current from two sources simultaneously — the 2D imager and the Wi-Fi or Bluetooth radio. That combined inrush can cause a momentary voltage sag on an aged or deeply discharged cell, dropping below the radio module's minimum operating threshold and forcing a reconnect. A fresh, fully charged pack delivers enough headroom to sustain both loads without the sag. If drop-outs persist after a full charge, check the wireless polling interval in the scanner's device settings before assuming a battery fault.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43324695576666,"sku":"BWCS-ZPS200BL-1","price":55.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43324695609434,"sku":"BWCS-ZPS200BL-2","price":63.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43324695642202,"sku":"BWCS-ZPS200BL-3","price":70.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-ZPS200BL-1.webp?v=1778122648","url":"https:\/\/batteryweb.com\/products\/zebra-ps20-replacement-battery-37v-3350mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
