HT600 146-162?

According to the Model Specific Page, it says 146-152, my radios inner at the VCO says 146-162....

Is it a typo on the ht600 page or my radio a odd split?

The HT600 Service Manual, on the VHF Transceiver schematic diagram, shows the following frequency table for both 2W and 5W radios:

L: 136-150.8 MHz
M: 146-162 MHz
H: 157-174 MHz

You can draw your own conclusions about the accuracy of info on the model-specific pages.

I've found the same thing.
Just enter the frequency and see if it'll take.
The printed spec on the radio mostly identifies which range the software wants to see, rather than hard endpoint numbers.
Note that even if the software will allow you to enter a frequency out of the stated range, the radio most likely holds tune at a specific center frequency when it was last aligned on the bench.

You can estimate where that is on transmit at least by entering six channels' worth of frequencies across a given range, and looking at your power output into a dummy load. The highest power among those frequencies is where it's peaked up. You can resolve it further by programming another 6 frequencies above and below the peak seen already, and establish the bandwidth at whatever power level you can accept.

The Batlabs page is wrong, has been from day one, i've sent numerous emails about the split being wrong but nobody seems to care or update the website anymore.
