Several years ago, I bought a Refractometer for checking the Coolant strength.
Works good and very accurate.
Yesterday (for the 1st time) I used it to check the Batteries Specific Gravity.
If anyone isn't familiar with Refractometers, here's a LINK

Note: Some measure temp. in 'C' ... Mine is 'F'
Checking all 6 Cells (compensating for temp), I got readings of 1.228 thru 1.238 (Fair)
------------------------
1.250 - 1.400 Good
1.200 - 1.250 Fair
1.100 - 1.200 Recharge
------------------------
Although I plan on replacing the Battery every 4-5 years, I think checking the Specific Gravity
will be good PM work and may show me early a defective battery (by comparing cells).
Your thoughts and comments are welcomed.
