Battery Type
1. Deep Cycle Batteries
Deep cycle batteries are designed to provide power for longer periods of time at a lower discharge rate. They are commonly used for marine and RV applications, and are also a popular choice for sump pump backup systems.
Deep cycle batteries come in two types: flooded and sealed. Flooded batteries require regular maintenance, as they need to be filled with distilled water every few months. Sealed batteries, on the other hand, are maintenance-free and have an enclosed design that prevents acid leaks.
One of the best deep cycle batteries for sump pump backup is the AGM (Absorbent Glass Mat) battery. AGM batteries are sealed and maintenance-free and are designed to handle high discharge rates. They also have a longer lifespan than traditional flooded deep-cycle batteries, which makes them a popular choice for sump pump backup systems.
The VMAXTANKS VMAXSLR125 AGM Deep Cycle 12V 125Ah battery is a top-rated battery for sump pump backup. This battery has a long lifespan and is designed to handle high discharge rates. It comes with a two-year warranty and is maintenance-free.
2. Lithium-ion Batteries
Lithium-ion batteries are known for their high energy density, long lifespan, and fast charging times. They are commonly used in consumer electronics and electric vehicles and are becoming a popular choice for sump pump backup systems due to their low maintenance requirements and lightweight design.
