As I mentioned they have to fit my boxes which are a snug fit in my console, so large leisure batteries are out, and 096 batteries are good, or I suppose something smaller.
I found the Tanya site, very useful, and how I worked out I have 096Rs in there at the moment.
First thing, fully charge your batteries (independently) using a good charger at appx 5Amps.
Take a simple voltage reading using a DC Volt Meter set at 20 Volts.
Here are the readings Good to Bad:
VOLT READING CONDITION
12.6...................100% GREEN
12.5.................... 90% GREEN
12.42...................80% GREEN
12.32...................70% GREEN
12.2.....................60% GREEN
12.06...................50% GREEN
11.9.....................40% GREEN
11.75...................30% YELLOW
11.58...................20% YELLOW
11.31...................10% RED
10.5.....................0% RED
If in green a load test should also be done, followed by a starter amperage draw - all done the above done after cleaning the battery terminals and checking starter and ground connections for tightness and corrosion.
