I think the five different batteries will work
with any (of those) tools. All batteries are
18V Lithium but the Ah's are 1.3, 1.5, 2.5, 4.0
and 5.0. So I think they have the same power
and interface, thus works for all, but the "Ah"
(Ampere hour) unit seems to suggest the longest
use before recharge for the 5.0 Ah version.
Yes, that must be it.

indoor use means use indoors or gently
outside on a nice day never get wet. a weenie
tool. construction tools are not described
as 'indoors'.

Right, actually I read the manual only *after*
buying the tool! Had I seen that remark I would
have bought the outdoor version.
Indoor only... c'mon.
