Forum Discussion
This is a common question here. Are six volt pairs or 12 volt singles better.
(NOTE: you have 2 pair or 2 singles in your question)
The answer is a bit more complex than YES/NO but the answer boils down usually to Six Volt pairs are best.
The reason: COST.
now... Here is why.
When you talk about 12 volt there are many different batteries,, Group 24,27,29,31, 4-D 8-D and dozens of others not listed.
Each battery is a diffeent size.. Group 24 for example is about 75 amp hours.
8-D around 250. (They are heavy and expensive).
The better question is this: What TYPE of battery.
Starting batteries like to be well fed, If you run them down to half full they get kind of unhappy and may well not recover.
Marine/Deep Cycle are starting batteries first, with lip service to deep cycle, Though they can recover from a lower discharge than an engine type battery, they still object to 50 percent
DEEP CYCLE batteries, such as Golf Car batteries, do not object to 50% discharge, provided they are recharged swiftly.
And when it comes to DEEP CYCLE the common GC-2 Golf car battery is the most popular, it's made in great quanities and thus costs less per unit than other large lead acid batteries.
HOWEVER: There are a couple of golf car companies using 12 volt batteries now,, This is going to result (over time) in 12 volt DEEP CYCLE batteries dropping in price.
Testing says I need to replace my GC-2's soon. At 8.5 years they finally bit the electrons.
