Charging a 12v Sealed Lead Acid Battery?
Hey guys and gals, I need some help finding a good charger for a battery I'm using in a project of mine.
This is the project: http://www.youtube.com/watch?v=KsLaKnL_GRs
Now, it's currently running off of an old 12v 6Ah motorcycle battery, but I'm looking at purchasing a pair of 7Ah sealed lead-acid scooter batteries because:
1. they're new
2. they're meant to be constantly recharged from a near-dead state
3. they're cheap as chips.
Thing is, now I need a charger for them. I'll only be using them one at a time so I only need to charge them one at a time, but I've never made anything using SLA batteries before now so I'd like some advice on what kind of charger to get.
I was looking at this guy here (http://www.amazon.com/Wild-Game-Innovations-12-Vol... or this one (http://www.amazon.com/Battery-Tender-021-0123-Juni...

This charger rated 500mA. To charge 7AH cell fully, charge time is 14 hours.

That is what it should read when it is without a load. A car alternator will put out 14.5 volts when charging a 12 volt battery, if it did not have a higher voltage, then it would not take a charge. The energy must reverse the chemical process in the battery so it can store the energy.
