Sump Pump Battery Reviews by Comparison

at Pumps Selection
 
 
 
What is unique about Sump Pump Batteries? 
  • Electricity is not made by them; they store it. 
  • 100% efficient cannot be attaines since some energy is lost to heat and chemical reactions when charging and discharging
  • Lead acid is used in flooded (wet), gelled and AGM (Absorbed Glass Material); however the contruction of their plates is different.
  • Plate thichness of the positive plate matters. This is the plate that gets eatten over time.  Thicker plates last longer.
  • They are grouped by amp hours.  Group 24 is 70-84 amp hours; Group 27 is 85-105 amp hours. Group 31 is 95-125 amp hours.
  • Calculation of continuous runtime is determined by the number of battery rated amps divided by the number of amp hours required by the pump. For example, a 6.5 amp pump will run approximately 12 hours with a Group 24 battery rated 70-84 hours.
  • Gell batteries must be charged at a lower voltage than flooded or AGM batteries. Overcharging a gell battery causes voids in the gell which never heals and causes loss in battery capacity.
  • AGM batteries require no maintenance, are sealed thus having no fume, leakage or spilling. Adding these features raises their price to twice as much as the flooded batteries.
  • Flooded batteries are more prone to leakage and fumes. If this is not a concern, these are the cheapest batteries to purchase.
