Which Type Of Battery Is Best?

Hey,

I built a rig where a Lead-Acid battery is charged from the output from a wind turbine, then the battery keeps a 1 watt light lit continuously for approx 1 day. Is the Lead-Acid the most suitable for this application or would other battery types be better, if so why? I understand with regard to lithium ion they have an issue with expense and they degrade significantly over a couple of years but what about NiCad or Alkaline batteries do they offer anything extra when compared to Lead-Acid?

Thanks

Generally speaking, if weight isn't an issue, then lead-acid is probably the best choice as far as cost goes.

Other batteries have higher density storage, but at a cost, and if the battery is stationary, density (power/weight) has no value.

If you go with a decent charge controller and a sealed (or gel) L/A then there is no more maintance either (else you have to periodically check water levels)

Alkaline batteries are not considered rechargable.

Any good recent study on battery charge leakage data, across differenty types?

Cell leakage is usually a small fraction of cell capacity - the worst I know of are high capacity Nimh cells - which you wouldn't want to use anyway.
