just bought a duralast battery at autozone (fwiw), and it says to charge at 500ma for 12 hours. I only have as low as 1A to trickle charge. is that gonna be fine? I can't find a 500ma charger anywhere.
Simple answer...no.
Don't bother reading the rest...
I mean it! Stop right here. Things will stop being simple, I warn you.
Hey, I'm not kidding, buddy! Just move on to the next post.
....Ok, I warned you!
There are as many brands and styles of chargers as there are vehicle brands in the world. ... And, they all have different capabilities.
Some chargers list only their max capability. Cheap chargers are seldom constant current type, or have a voltage regulator. So, I have doubts your "1 amp charger" does so under all connected conditions. But...
You didn't tell us the battery model numbers.
you didn't tell us the charger brand/model numbers.
You didn't tell us a BIKE brand or model number.
So, I suspect the information hiding was done so you could hear it was ok to do whatever you wanted. So, go ahead! It ain't my battery!
But, maybe you should 1/3 the charge time, or don't expect the new battery to achieve maximum potential. It's all about the chemistry. Ready for Chem 101? It's really simple, you know.
Yes, you can damage a battery (catastrophically or subtly) by exceeding manufacturer recommendations. (Kinda why they give you guidelines.)
Oh, and since you can't sop reading, here's another simple question.
The doctor says I should clean my fingernails with a tooth pick. I only have a hatchet, will that be ok? Will there be blood?
Oh, and here's another simple question. How long will it take to get to Mars?
Is there a limit to the simple questions in a single post?
Cheers,
