It's unusual, but entirely possible, for a shock absorber to fail on any car at any time - how the car has been driven over the first 4 years of it's life (before you got it) would have a huge bearing on whether this would be likely or not. You certainly can't blame the battery pack weight for this (unless you can find large numbers of other similar cases to indicate that this is a common problem to this model).
I'd never replace a single shock absorber. Always in pairs. You must remember that the non-broken one also has nearly 5 years worth of wear on it, so it may well absorb and rebound differently to when new. Having one side of your car behave differently to the other is a recipe for finding the landscape - sideways !
