              Exactly what we needed.
              After we endured a 7 day power outage a few weeks ago due to an ice storm, we wanted extended protection for our sump pump.

              Easy to connect. Have not had a power outage since installing it, but I have no reason to believe that it won’t double my sump pump backup time.

                Cables are of good quality imho and long enough for me as my batteries are next to each by plan for easier maintenence. Cables are an easy install btw. You'll need another battery box and home depot sells the NOCO HM318BK Group 24-31 Snap-Top Battery Box as a great option for your second battery and compatible with watch Dog batteries. The their agm battery is a group 24, so you can use the included divider if you like as the agm battery is a little smaller than their standard lead acid battery which is a group 31 btw and fits oerfectly, so stop looking and consider the noco battery box i nentioned for your 2nd battery box. They have easy returns if you really dint like it, but I'm confident you will, especially with their great price and free shipping.

                By installing The Basement Watchdog Parallel Battery Cable, you instantly double your battery back up for your 12 volt emergency sump pump. I installed the parallel battery cable last month, to extend the run time of my emergency back up pump. The quality of the cable is excellent, and I would definitely recommend this product!

                Product is well made with quality materials and I have no complaints with the way it's put together. However, it's a bit short to bridge two batteries if they are in separate battery boxes. There is not enough slack to work with in order the close both battery boxes.
