Can't really comments on it's reliability over a long period of time, but it was very easy to install, and was charged when I brought it home (13.05 volts). The voltage has increased slightly since being installed and charging with the backup system. My old Basement Watchdog backup has the probe that detects low battery acid. All you need to do is attach that probe to the positive battery terminal so the alarm shuts off (it says so right on top of my battery.)

    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
