hello,the zoeleer website states the battery must have minimum 105 amp-hr,do you carry that battery? Thank you.Perhap the Zoeller info is wrong.
Answer
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).
