Re: What type of batteries to use for wind turbine
Don't use Marine batteries--They are not designed for deep cycling and will not last very long.
From our host's (NAWS) Battery Faq:
If this is your first system and you are on a budget--"Golf Cart" Batteries at $80-$100 (guess), Trojan T105-RE 6 Volt, 225 AH Deep Cycle Battery $154.50, or similar low cost batteries for a "training set"...
- Starting: 3-12 months
- Marine: 1-6 years
- Golf cart: 2-7 years
- AGM deep cycle: 4-7 years
- Gelled deep cycle: 2-5 years
- Deep cycle (L-16 type etc): 4-8 years
- Rolls-Surrette premium deep cycle: 7-15 years
- Industrial deep cycle (Crown and Rolls 4KS series): 10-20+ years
- Telephone (float): 2-20 years. These are usually special purpose "float service", but often appear on the surplus market as "deep cycle". They can vary considerably, depending on age, usage, care, and type.
- NiFe (alkaline): 5-35 years
- NiCad: 1-20 years
Many people kill their first set of batteries. It is just a fact of life.
Also, it looks like batteries that will last 2x longer also cost 2x as much--So the long term pricing is not much different--Although, you don't have to live with the issues of a "dying bank" as often with longer life batteries.
My suggestion for tools to help you keep your battery bank healthy:
- Get the Remote Battery Temperature Sensor for your solar charger (if available option)
- A good Hydrometer
- Good DMM (digital multi-meter)
- Battery Monitor (Victron Energy is another brand). Trimetric is a good lower cost unit
- If you have parallel battery or solar panel cabling, a DC Clamp Amp Meter
