Less is definately more for a motorcycle battery1978 GS 1000 (since new)

I guess I'm a little bit late in the game, but just for information's sake.
When a battery goes bad, it can still read decent voltage around 12V. A quick way to check the battery is to put your meter on it, turn on your ignition, and you should see something like 2 - 5V. That means that the internal resistance of the battery is really high. The reason why you read 12V before is because it's not under load. No load = no current = no voltage drop = you get ****ed off cuz you think it's something else that's the problem.

Alright. Got the new battery in. 12.56 with the bike off, 13.48 with the bike on, and mid to low 14's with bike revved. Went for a ride for about a half hour, came back, turned the bike off, checked the voltage, 13.18. Is this too high or am I fine. Maybe I should just stop worrying and ride the damn thing.

It looks good. After few days riding (use) and standing overnight it should test close to 12.6 volt showing its good.

Short answer to the actual question....
Whats the easiest way to test a battery?
Take it to your nearest Autozone/Checker and even some Walmarts. Hook it up to the 'puter and can get a full analysis. Is it shorted? Too steep a current or voltage drop? It will tell you with out guessing.
Besides, if you think ur battery is bad you gotta go to the store anyway to get the new one.....
I'm just sayin.....

The Battery Tender Plus retails for $60, might be found for less.
The Schumacher unit retails for $28, but Wal-Mart has them for $18 and some change, meaning it's less than $20, including tax.
