CR17280, 600mAh, 3.7V batteries for the RELAY G10 wireless system. These are a perfect match in size to the genuine, hard-to-find batteries. (The battery removed from the device is on top in the second photo, and the battery for sale is on the bottom.) Due to the MOQ (Minimum Order Quantity), I ended up with more stock than I needed, so I'm selling the surplus. 【Product Condition】 ・New / Unused ・Operation not confirmed (as the product is unused) ※ I have confirmed the operation of the ones I replaced myself. 【Notes】 ・As this is a personal sale, there is no manufacturer's warranty. ・If there is an initial defect, please contact me before rating the product. ・Please be sure to check the model number and specifications before purchasing. ・This listing will end when the stock runs out. ・Only the battery is for sale (as shown in the fourth photo). ・You can find instructions on how to replace the battery by searching online, but I can offer some advice after purchase. Please feel free to ask any questions in the comments. 〇 Details - Model: For RELAY G10T - Type: CR17280 - Capacity: 600mAh - Voltage: 3.7V - Color: Green Thank you. ※ I try to ship as quickly as possible, but please note that shipping may be slightly delayed due to the year-end and New Year holidays.
