Zoeller 10-1450 - Aquanot 12V Deep Cycle 100AH AGM Battery

Thank you for your interest in Sump Pumps Direct. The Size 31 “Wet Battery” No. 10-0761 , will provide an approximate 200 minute reserve capacity while the Size 27 “AGM Battery” No. 10-1450, will provide an approximate 175 minute reserve capacity. The minimum battery requirements for the 585 is a deep cycle, size 27, 175 minute reserve capacity battery. In short, either battery will work, though you may realize a slightly shorter run time with the 10-1450 battery.

Thank you for visiting Sump Pumps Direct. In answer to your question, battery ratings can get a bit confusing since ratings can be determined in amp hours (AH), amps and reserve minutes. While it's true that the manual does list the required minimum Amp Hour rating at 105, the Zoeller website also lists the following:

Battery Life:
The estimated life of a fully charged (175 minute reserve capacity) battery when the pump is operating continuously is approximately 7 ½ hours. Example – The model 510 at 10 ft. head will pump 1,296 GPH. Most backup systems require intermittent pump operation. All models will provide protection for extended periods of time dependent upon stop-start requirements. Note: The 510 offers extended backup protection if the regular primary sump pump fails.

Performance Data:
Pump performance is based on the use of a fully charged 12 Volt, (200 minute reserve capacity) for models 507 and 510, deep-cycle battery with no deficiency and less than two years old.

Aquanot® Battery:
Size 31 “Wet” P/N 10-0761 (69 lbs./31kg ), shipped via truckline only, 200 minute reserve capacity
Size 27 “AGM” P/N 10-1450 (66 lbs./29kg), 175 minute reserve capacity
Minimum battery requirements: deep cycle, size 27, 175 minute reserve capacity

In addition, the manual for the 507 Sentry Battery Backup also lists the following:
There are millions of batteries manufactured each year, so it is impossible to guarantee consistent quality. A defective battery will never become fully charged and may damage the charging circuits of the Control. It is for this reason that Zoeller offers its own line of batteries. We offer both a Water/Acid Deep-Cycle Battery which can run the pump continuously for over 7½ hours, and a Maintenance-Free AGM Battery, which will power the pump for over 3½ hours. These times are based on continuous pumping at 10' of static head. Actual times will vary depending on static head, volume of water entering the pit, and the condition of the battery.

Follow these recommendations:
• Use a B.C.I. size 27 deep-cycle battery, 175 minute reserve capacity, or larger.
• Do NOT use a “maintenance-free” battery unless it is a Gel-fi lled or AGM battery.
• Replace your battery every 3 years.
• Do not let corrosion build up on the battery terminals.
• Do not place your battery on a concrete fl oor where it will discharge faster.
• To check specifi c gravity, follow the instructions on a hydrometer (not applicable for Gel or AGM batteries).

Replacement of battery backup batteries really depends on the number of cycles used and the age of the battery. Most batteries need replacement after approximately 3-5 years. You can always take your battery to a local battery supplier or auto parts store to have them check you battery if you want to verify it's condition.
