Answer: 
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 Read More

Answer: 
This Basement Watchdog Big Dog system will support 2 batteries together in a parallel connection to extend the run time in an outage. The batteries need to be the same model and age. We at Glentronics also manufacture a set of cables to make the parallel connection. They are sold at Home Depot (model# PJC).

Big Dog Computer-Controlled AC/DC Battery Backup Sump Pump System is rated 3.9 out of 5 by 33.

The only thing we've replaced in 16+ years was the battery. Once. We use this unit as it is intended for. A backup in case the power goes out. We have two sump pumps and this is a secondary pump. We have lost power many times and have faith in this 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.

Rated 5 out of 5 by from I bought the Watch Dog battery back up system last summer after installing drain tile in my constantly wet basement. My sump pump now runs 24/7/365. We had so many power outages last summer that I flooded the basement several times. I purchased the Watch Dog system and have been dry for the first time since moving here 9 years ago. It has saved me from bailing water from the pump well to renting a generator numerous times. Last week the main pump failed and it was 3 days before someone could come and replace it. The Watch Dog took over, running on A/C electrical from the house and when the company came to replace the main pump he told me with the amount of water we have it's a good thing I bought that system. Awesome Product!!

Rated 5 out of 5 by from BONUS--it's compatible with an AGM battery DItto other Excellent reviews. The only thing I'm adding is the fact that the electronics on the Big Dog model (as well as the inexpensive BWE ) are fully compatible with an Absorbed Glass Mat (AGM) battery according to Tech Support. Why is that important? Because, AGM batteries don't produce hydrogen gas when they charge--so pilot lights and other ignition sources in the basement pose no problems! They won't leak or spill even if they're broken, they survive most freezes, and warranties are twice as long as a lead -acid design. (I am NOT an advertiser--just a very happy camper)

Rated 4 out of 5 by from It Works and Has Good Displays I installed the pump myself (no experience). You just need to be willing to cut and glue PVC. It took 2 hours to install. The operation of the pump is very straight forward and easy to understand. The controlling unit has good displays. One month after installing, a big storm knocked out our power. The unit kicked in and took over for the 4 hours we were without power. Water was coming into the sump fast, but it had no problems keeping up. You may be happy with the cheaper versions, I don't really know all of the differences. I do know that I have peace of mind with this thing installed. I would have rated it as 'excellent' but at $560 including battery and acid, it seems like a good value (not an excellent value).

Rated 1 out of 5 by from Unit quit working after 1 year and manufacturer refused to warranty it. I spent over $500 for the big dog system and the company would not warranty it because it was coming up as an older serial number. Apparently you need to check the number of the unit you buy. Bad customer service.
