I'm sorry to say that we do not offer any separate components from any battery backup systems. You might try calling Basement Watchdog tech support at 800-991-0466 for further assistance.

Per the instructions for the Basement Watchdog battery backup systems, DO NOT use a maintenance-free or a sealed battery. They are made of different materials and
will trigger a false “Battery problem” alarm.
A new Basement Watchdog 7.5 Hour Standby Battery, model 30HDC140S will run this system for a minimum of 7.5 hours continuously. However, most of the time the pump will turn on and off, and the battery will run the pump intermittently for days. In addition, the unique materials in the battery enable it to last for five to seven years in standby service.

Yes, the controller will keep the battery charging and the pump running indefinitely if needed. This is true for the Basement Watchdog model BWE and the BWSP stand alone battery backup systems as well.

If you are at all handy around the house and are somewhat familiar with plumbing and PVC, it's not all that difficult. The OWNERS MANUAL is available to download by clicking on the "SPECS" tab and looking on the right side of the page in the "Download Documents" section. There you will find all the installation instructions to give you an idea of what's needed to perform the complete installation.

The Model 30HDC140S is available for $139.99 (without acid) and will run this pump for approximately 12 hours. The battery is also sold with the acid for $249.99.

To be completely sure your backup system is fully functional during a power outage or weather event, these systems need to stay plugged in at all times.

You can use any deep cycle marine battery, as long as it is not maintenance-free. However, there are several advantages to using a Basement Watchdog battery. The Watchdog battery accommodates the system’s fluid sensor which will sound an alarm when the battery needs water…a very important feature, since a dry battery will not perform. In addition, Basement Watchdog batteries run longer per charge, and last years longer. A typical marine battery will last 2-4 years, while the Watchdog battery will last approximately 5-7 years. Basement Watchdog batteries are shipped dry (without acid) so they stay fresh on the shelf indefinitely, while wet batteries have a short shelf life.

Update 11/16/15: Basement Watchdog has changed this requirement around 2013 and their backup systems will now accept maintenance free batteries. Please refer to their updated installation manual for instructions on the proper method for this battery installation.

This system does not include a battery, and that is what determines the hours of backup a system can provide. There is also the factor of how often a system is running that determines the amount of backup time.
