I would agree with Kramer regarding the reliability of lead acid batteries. However the new chemistries of lithium are becoming available. I've seen some you-tube video where some people have installed lithium packs liberated from a Nissan Leaf and showing some excellent results coupled to their solar PV.

For the reliability the manufactures are warranting the batteries for eight years and this would be a very conservative time frame as I'm sure they would not what to be supplying new batteries seven years out. I have read the Tesla Roadsters produced in 2008 has a lithium pack that showing some very good life as measurements of 90% of the capacity remains.

As more and more electric vehicles meet their demise with trees, poles or other cars, a lot of lightly used batteries will be available to the eco-renovators for a lot better price than Lead-acid.
