Re: Where was that post about battery type???
I would guess that it isn't supposed to be maintenance free, because that's a misleading term. You still have to take care of the battery. I couldn't justify the extra cost if you have easy access to the battery. Regular batteries can last much longer if properly maintained. A good place for a maintenance free battery is in, for example, a motorcycle, where the battery is buried and you have to start removing parts to get to it.
