Not really; without entering into much details:
Batteries (usually most rechargeable) tend to diminish their max recharge. (its an exponential distribution.
The best to do with rechargeable is to recharge them only when they hit rock-bottom; if you recharge when the charge still has over half the charging capacity you are shortening the lifespan of your batteries.
Usually, the lifespans is expressed as "charging cycles" as , over a certain number charges last less and less.
Batteries loose charge even if they are not being used, and most of this is because of electromagnetic fields within the device. If you care to read further about this you could google "hysteresis curve".
