Received product. Yet to test. Hope that product is good.
I bought this battery to replace my faulty battery for wireless vaccum cleaner. My faulty battery's specification was 7.4VDC, 4000mAh. So I ordered 7.4V, 5000mAh battery from. When I received a battery, I tested it by connecting to motor. It was running normal for less than a minute and then become slow running (low RPM) and stop due to low battery. I tried to recharge the battery but unable to recharge. Suspected that battery quality is not good or may be sent me lower mAh battery.
not arrived slow communication,i don't know whil they go back the money?
