I've replaced both a couple of times. This last heavy rain our backup went out.... and so did I, to get a replacement. The next day our main pump went out. So. .. back to the store I went. I should be good for a few years, now. There's cheaper ones out there, but I have to have one that I have confidence in. That's Watchdog.

It was easy to install. so far no issues. I have to wait and see how long this AGM battery works for the price I paid. That is the reason to give a 4 star. earlier acid and water filled batteries never lasted more than 2 year even after taking care as suggested. Let us see

I don't know how I could be expected to know if it will live up to expectations at this point. This is the second request for this already. I'm not happy with that in itself.

I bought this one instead of a "wet cell" battery because I wanted a no-maintenance battery. Who wants to keep checking the battery and adding water? I was able to hook it up to my Basement Watchdog sump pump system (a primary pump with a battery-powered backup pump) with no problem at all. Just make sure you connect the water level sensor to the positive terminal of the battery so the alarm doesn't keep going off.

WE HAVE 2 sump pumps, one on top of the other one. I would like to know do we need 2 standby batteries?

Asked by: Frances
Each one of our Basement Watchdog battery backup systems needs to have its own battery. If you have 2 Basement Watchdog battery backup systems, you need 2 batteries. If you have a Basement Watchdog battery backup on top of an AC powered pump, you only need 1 battery. For more information, please contact our customer support team at 800-991-0466, option 3. We are available to take incoming calls from 9am – 5pm CT Monday through Friday.

If using this battery for a backup system, how often do you need to charge this battery and what do you use to charge the battery? Thank you,

Asked by: Julius
All our Basement Watchdog battery backup systems include a built in charger with the control panel box. So if you have our system there is no need to charge the battery externally. If you are using a different brand of backup system, and it doesn't have a built in charger. I would recommend hooking it up to a small trickle charger or battery tenderer so the battery is always at 100%. For more information please contact our service team at 800-991-0466 option 3.

L'acide de densité 1.265, vient-elle avec la battérie? Sinon, où l'acheter? Homedépot.com américain l'offre (1.5 gal = 5.77 L), homedepot.ca apparemment non. Il existe des contenants de 20 L mais je voudrais acheter la juste quantité.

Asked by: Rudolfus
L'acide a une densité spécifique de 1,265 - si Home Depot ne le transporte pas, la plupart des pièces automobiles ou des magasins de batteries l'auront. Vous aurez besoin de 6 quarts ou 5.678 litres
