T-105 or T-105 Plus
Its time to replace my old batteries and I'm looking at these two types. The specs on them are the same so I'm wondering what's the difference between the regular and the plus model? Thanks!

another option is a refractometer to measure SG. slightly more expensive, but I've found a refractometer to be much more repeatable and much easier to read than getting the fluid level good and the float ok in a hydrometer.
But now it's a refractometer that I checked against my freese hydrometer.
OMG.. you let the cat out of the bag... now everyone will want a refractometer and check their batteries correctly.. !!!!!
