A Little More About Deep Cycle Batteries

The deep cycle batteries, as we can tell by the name, are designed to deliver continuous power and to be regularly discharged to their maximum capacity. Thus, they would be the most suitable batteries to get for your wheelchair, scooter, golf carts, forklifts and etc.

In as short comparison, high-rate starter batteries (automotive and powersports) are designed to deliver short and high voltage currents, whereas deep-cycle ones have a lot more benefits and can be used as a starter too.

Deep Cycle Battery

Deep cycle batteries can be discharged at around 45-80% of its capacity, however in order to prolong its life it would be best to discharge it no more than 50%. Those type of batteries usually allow around 300-350 cycles. They are rated in AH or minutes of runtime. The capacity is normally rated as a 5 HR (hour) or 20HR discharge. Their anatomy shows, they are constructed with thicker plates for higher density, active paste material and thicker separators. The alloys, that are used for the plates may contain more antimony, than the ones in starting batteries. We can also add that thicker battery plates are more resistant to corrosion, through extended charge and discharge cycles.

Usually, your deep-cycle battery would last around 5 years however, the good maintenance is what would ensure you its maximum performance. In particular, below are some tips:

  • Keeping them watered on the appropriate level
  • Prevent from discharging them more than 50% of their total capacity
  • Having the appropriate charger in place

Finally, it is good to know that deep cycle batteries are being recycled at around 98%. The plastic cases, lead plates, sulfuric acid, solder, and other metals are 100% recovered for reuse. The only part of a battery that is not recyclable is the paper separators that wrap the plates.

We could for sure state that deep cycle batteries would be the perfect choice for an application that needs continuous power for a longer period. Here at BatteryRush, we have a wide range of wheelchair and scooter batteries, as well as GEL and SLA.
