Hi team!...
just wondering... all of you..... what kind of battery do you use, for your wind-turbine (Amatek 30)????.... Car Battery?. I heard some people use Forklifts battery, but I guess are expensive.
when I'm ready to get one, what question do I need to ask? and sizes?.
Please every body post me the type of your battery, to get an understanding.

I think this Battery voltage chart is very useful for all to remember (if you can) or at least semi-remember, as I probably will...
Remember the battery should be at resting room temperature and not been charged or discharged for 5 or 6 hours before taking the reading.
%Charge = Volts
100% = 12.70
90% = 12.64
80% = 12.46
70% = 12.36
60% = 12.28
50% = 12.20
40% = 12.12
30% = 12.04
20% = 11.98
10% = 11.94

Hi Oliver,
Fully agree with Ben. If you can get hold of a set of deep cycle batteries that would be the best bet. Batteries from UPS (uninterruptable power systems), forklifts or submarines are great but not always easy to get hold of.
Deep cycle batteries are designed to be run down and recharged a number of times and last years. Automotive batteries are designed quite differently and have very thin plates that will warp and become useless if they are subject to the same use. They are designed to produce a lot of power over a few seconds to start an engine and then be kept fully charged by the vehicles charging system.
Leisure batteries, I think, are a more of a deep cycle type battery but of a lower quality so will not last as long.
Personally I have eight Varta leisure batteries (60Ah each) that I bought secondhand but are still just under a year old. I've recently bought some bigger deep cycle batteries that will be better than the leisure batteries so will be looking to get rid of my leisure batteries.
I will probabaly ebay them in the next few weeks but if you're interested in some or all of them please let me know and we can arrange something.
Cheers
Del. |

Deep cycle batteries are the best for wind/ solar applications, car batteries will work but not advised.
Better Generations Toby has a good piece here for you.
