is battery included with this system?

Asked by: newhome
This is incorrect this system does not include battery or acid. The system comes with the controller and pump. The box is included for the battery but the actual battery does need to be purchased separately. Please contact us directly at 800.991.0466 ext 3 for customer support if you are in need of further assistance

Can I purchased the battery only for the Watch big Dog unit , what model is it ?

I just need a replacement battery.
Asked by: mikeeg
The correct battery for the "Big Dog" system is the Basement Watchdog 7.5 hour standby battery. The model number for that one is 30HDC140S. Be sure to purchase the box of battery acid that goes with it. Usually the boxes of battery acid our sold in stores right next to the batteries themselves. If your local store doesn't have the acid in stock you would need 6 quarts of 1.265 specific gravity battery acid.

I had one computer go out (it was over 10 yrs old). The connection/replacement to the Big Dog/Watchdog went very smooth. Had in up and running in 40 minutes. I did have to call Glentronics to verify that the fan runs constantly on the Big Dog where as on the Watch Dog it would shut down. Glentronics customer service was outstanding, getting back to me promptly to answer my question. Very Happy with this product. The only complaint would be it is pricey.

Although it seems as if this unit is an expensive investment, it is GREAT and has saved my basement from a lot of damage after losing power for hours - not to mention personal belongings and property value. The customer service team is very helpful and knowledgeable about the produts they represent and I can rest assure that I can go out-of-town for any number of days and my property will be protected.

The no maintenance AGM batteries are a big improvement over the old lead acid batteries. There are also a number of improvements in the newest control unit.

Rated 5 out of 5 by from A must have for basements with sump pits This product has saved my basements on several occasions. The system has a powerful pump, charger, several monitoring features and easy to follow step by step instructions on how to install and troubleshoot the system. The company also has outstanding customer service. I used two 7.5 hour Watchdog batteries (in parallel) for each system which provides days pumping capacity. You would need a parallel jumper cable which I bought from the manufacturer. One piece of advice…although the system monitors the battery fluid levels, which works very well, I like to check mine when I turn the clocks back or just before going on vacation. Overall great product!!!

Rated 5 out of 5 by from Saved my basement many times This was the second system I have purchased and it has earned it's keep several times over. I live on 2 1/2 acres that are surrounded by wetlands. I have drain tile around the inside of my foudation so my sump pumps fill and drain about every 3 mins 24/7. So when the power goes out, which it has I can flood my basement 4" deep in 45mins. best thing I ever bought for the house besides the drain tile. Alarm goes off to tell me when the power goes off or there's a problem with the main pump. Only 1 problem. DON'T wait for the low water sensor to tell you when to fill with water. Do it once a year, trust me. I waited and we had a tornado that knocked out power for 4 days. Smoked the battery. Other than that, you can't go wrong. I own 2 systems. Well worth it.

Rated 5 out of 5 by from A Great Buy but..... EVERYONE READING THIS.... make sure you UNDERSTAND THAT THIS DOES NOT COME WITH A BATTERY OR ACID. I wish Glentronics would simply package the battery with this. Its sort of dumb.... you need a battery since the system will not work w/o it. Yet they sell it seperate. I ended up using a marine battery from my boat until I got time again to go to home depot to pickup the Glentronics / Watchdog battery. (Another $100). This is a great system. I have put it in unfortunately after the fact. Will the lesser models work.... yeah I imagine they would but when I saw the water pouring in over the sump pump cover after the power went out, it was scary to see how much water was coming in. Within 2 - 5 minutes, our basement (approx 2000+/- sq ft) was covered in about 2" of water. Soooo that being the case, I opted for the most GPH pump. I was thinking about putting in a generator but decided on this for the interim. This unit also gives you more information feedback than the other 2 lesser models. It also tells you how much more battery life is left.
