163 - time and date were not set.
You have to go into the bios and set the time and date after you have removed the battery then have replaced it, Save bios settings.
NOTE that if you can't get into the bios Setup, setting the time and date in your operating system on the computer will usually, if not always, set the the bios to the same time and date values as in the operating system.
161 - dead battery (or it's connected backwards)
1. Go to "Backup Battery Checkout"
Page 17, 18 of PDF - Backup Battery Checkout
If the battery voltage is okay, and if it's plugged in such that it's polarity is correct, then if you still get the 161 error, you probably need to replace the system board (motherboard).

If the plug on the battery's wiring can be plugged in either way, make sure it's plugged in the right way - there may be a + beside one side of the connector it plugs into.
If that's plugged in backwards, or if it can't be plugged in backwards but the plug is wired backwards, the bios will behave as if the battery is dead or it's not there.

Did you get the correct non-rechargable battery ?
This laptop cannot charge a rechargable backup battery, and if you got a non-rechargable one that is not compatible with that part number / this laptop, it may be wired backwards to what you need it to be at the plug.
