1.5 ah
Yes as long as they are both 12 volt batteries.
The difference is 0.6 AH, or 600 mAH.
Amp hour
The first choice was the best: 3 x 12 v 12 Ah will give a 36 v 12 Ah battery. In series the same current goes through all the batteries so the Ah capacity does not change.
V is the batteries rated voltage. Ah is the amp-hour of the battery. This is a rating of how many amps it can supply for a given period of time. For example a 600 Ah battery with a 100 A load means that the battery should last 6 hours.
They are mostly the same. The UB1280, which has 8 AH, can be used to replace the UB1270, which has 7 AH.
Its hard to say with the limited info we have. The ah or "amp hour" rating is how long the battery can sustain itself.....thus the 7 would make it a better choice. However, we do not know if the cranking amps are different between the two. This would make a difference in starting power. it really depends on how you look at it. It also depends on the car. or which is cheaper
Depends on the max allowable discharge rate of the batteries, and what current the load - the consumer that's hooked up to the batteries will draw.
The ampere-hour rating of series connected batteries is the same as that for one battery, so the ampere-hour rating of four 65 Ah batteries in series is still 65 Ah. The reason for this is Kirchoff's current law - the signed sum of the currents entering a node is zero - or - the current at every point in a series circuit is the same.
Similar batteries are rated 0.90 Ah

The AH means Amp Hours and is a measure of how much electricity the battery can store. Thus if the 12AH and 15AH batteries were connected to THE SAME device (one after the other) the 15AH battery would run the device for longer than the 12AH battery.
