用户：我们公司在2013年采购的理士蓄电池DJ300(2V300AH)型号的108只，给直流屏GZDW系统供电，近期停了一次电，直流屏直接关机了，用电压万能表测量电池电压都在1.5V左右，电池存不了电了我想更换一批蓄电池，请问理士：能依旧换新吗?

理士客服：您好，谢谢您一直以来对我们的支持，我们可以依旧换新的方式销售，旧电池会根据当时的铅价定价，可以折扣成新理士电池的货款。

用户：请问你们能上门安装，做充放电测试，回收吗？

理士客服：我们有专门的安装工程师，可以上门安装，充放电测试，回收等服务。

用户：如果订货的话，几天可以到货并安装？

理士客服：不是偏远地区我会在7个工作日内把货送到并安装好。

用户：好的谢谢，定下来联系你们。

Customer: 108 of the Reyes batteries DJ300(2V300AH) purchased by our company in 2013 supply power to the GZDW system of the DC screen. Recently, the dc screen was shut down, and the DC screen was directly turned off. The battery voltage measured by the voltage multimeter was about 1.5V, so the batteries could not store power. Can you still renew it?

Customer service of Reese: Hello, thank you for your support all the time. We can still change to a new way of sales. The old batteries will be priced according to the lead price at that time, and we can discount them into the payment for the new Reese batteries.

User: can you install, charge and discharge test, recycle?

Customer service: we have a special installation engineer, can door installation, charge and discharge test, recycling and other services.

Customer: If we place an order, how long will it take for delivery and installation?

Customer service: It's not a remote area. I will deliver the goods and install them in 7 working days.
