FYI, I replaced the SLA battery on my SP Star a couple of months ago for $52.80 including shipping and got a 22Ah instead of the 21Ah that came with the machine from Batterysharks.com. You have to also buy 2 NB to F2 Terminal Adapters, which I found for $.56 each with free shipping from Impact Batteries. YMMV. No affiliation disclaimer, yada, yada, yada.
Universal Power UB12220 (40696) Battery (Replacement) $40 + $12.80 S/H
The SP Lite uses a lower capacity battery than the Star which should be cheaper than that.
