Batt loses 1% charge each day. Let it sit a month, 30% down is the batt. I want to check my charger's output. I walk up to the battery with a volt meter, read the number. For argument sake, say it's 12.3v. I hook up the charger, read the battery again. It now reads 14v+ so I walk away for half the day. Or say I wake up, go out and check the battery with the charger on overnight. I should read 13.+v for argument sake. I pull the plug on the charger and read the battery's volts a half hour later. The batt now reads 12.8v. For argument sake, that's the ideal static number. To test if the charger is running smart, draw the battery down in voltage. I now hook a high beam light across the battery posts and draw the batt down. This took about a minute of draw. I hook the charger back on and see if the charger is over 14v+. I wake up the next day and see if the smart moved the voltage down below 13-14v for argument sake.
This shows me the charger turns smart and cuts the charge down. This also shows me the draw is being addressed by the 14v range kicking back on.
Option:
I want a charger rated around 1.5a. This is not a smart charger, but a preset 1.5a output. Theory goes like this:
1. I buy a 12N12a battery. I move the decimal point to the right one time to see what rated charger I am looking for.
2. I buy a 12N14a battery. Move the point over, I want at least a 1.4a charger. I cannot use my 1.2a charger and have .2v down.
3. I charge the battery by its rating. So, I would charge a 1.2a battery for 12 hours [literally] before putting it into service.
4. I charge the higher amp rated battery at 1.4a for 14 hours.
5. I can charge a 12a battery with a higher rated charger, but math wise, I cut the hours down some.
6. I cannot charge a high amp batt with a low amp charger. That extra .2v will never be at full charge.
Verify:
If my bike is a parasitic system and I want to find out, I remove the ground cable off the battery. I then touch the ground strap to the batt post I just removed. If it sparks and arc, it's parasitic as in; keeps the clock timed, has to calc memory with a relay kind of electronics. No arc, no [parasitic] draining the battery down.
Another d-runk-inn post, dipping the pen into a bud light, budd and lite; you pick.
