It matches OEM part number 82-133770-01 and slots directly into both scanner models. Capacity is rated at 2.59Wh, consistent with the original specification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eCS3300 and CS3070 shared platform:\u003c\/strong\u003e\n    Both scanners run the same 3.7V battery rail with an identical connector footprint and BMS handshake protocol. One replacement cell covers both models without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through charge and discharge cycles on the CS3300 platform. The BMS accepted the pack cleanly, voltage held stable across simulated scan-trigger bursts, and the cradle reported a normal charge state throughout.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-shift charge protocol for CS3300 and CS3070:\u003c\/strong\u003e\n    After installing, seat the scanner in its cradle for a full charge cycle before starting pick-and-pack work. Scan trigger inrush current peaks when the cell is near minimum charge — a pre-charged cell stops the BMS from tripping on the first heavy scanning burst of the shift.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCradle showing a charging error on a freshly installed pack\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eA charging error on the cradle display after fitting a new battery almost always points to contact resistance at the dock pins, not a fault with the cell itself. The CS3300 cradle uses spring-loaded gold contacts that oxidise over time. Oxidation raises resistance enough that the dock misreads the pack's charge state and throws an error. Wipe the battery contacts and the cradle pins with a dry lint-free cloth, reseat the scanner firmly, and the error typically clears within one charge cycle.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eScanner losing wireless connection during a rapid scan burst\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eDuring fast back-to-back scanning, the CS3300 draws simultaneously from its wireless radio and its imager — two high-draw loads hitting the cell at the same time. If the battery voltage sags below the radio's minimum threshold, the wireless link drops mid-session even though the scanner still appears powered on. This is more common late in a shift when cell voltage is already trending down. Starting the shift with a fully charged pack keeps voltage above the 3.4V floor that the radio module needs to hold its connection.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43324860465242,"sku":"BWCS-MC330SL-1","price":22.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43324860498010,"sku":"BWCS-MC330SL-2","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43324860530778,"sku":"BWCS-MC330SL-3","price":27.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-MC330SL_1.webp?v=1778123334","url":"https:\/\/batteryweb.com\/products\/zebra-cs3300-replacement-battery-37v-700mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
