Battery decline

Has anyone noticed their batteries declining faster than expected?

I've had my original battery for almost 2 years now and I've lost probably 40% of the original capacity. I bought a replacement battery (figured it was way cheaper than buying a new bike, plus now I'd have two) and that one seems like it has lost maybe 15% in less than a year.

They're indoors when I'm not on the bike and I keep them half charged if they're just going to be sitting. I would think these would be quality batteries since they're from Samsung, but are they not?
