I was going to suggest the same, if you need a battery to last an extended period of time for a workbench time scenario go for a marine or car battery (The robot batteries are 18Amp-Hours so choose accordingly). If you don't need a lot of current, a deep cycle battery should allow you to run even longer between chargings (correct me if I am wrong but deep cycles have less cold cranking amps at the cost of greater capacity)
Al, I was under the impression that even with no load on the battery chargers aren't a very clean source of power, is this true?
