Thank you. I forgot to state that "Ah" (amp hour) is a measure of capacity.

And Ben Sherman. The type of charging we use is called absorption. Most laptops and mobile devices will use this type of charging as well.
Float charging is more commonly known as trickle charging. It is used on High Performance NICD, NIMH, LIPO, and A123 batteries to keep them from self discharging. This method doesn't hurt or damage the battery. where as if you did that with a lead-acid battery it would start to damage it after a while.

Get a new charger...Ours do not take 3 hours to charge ... usually close to 20-30 minutes. Our charger can charge a battery at up to 15 but we usually charge them at 10 or 5. It can also choose what to charge it at, somtimes it chargers at 0.2, but this takes FOREVER to charge them fully.

Here is the link to our new chargers ^^ ... i dont think america has Canadian Tire though :$
The reason that you can charge your batteries so quickly is because you have the ability to charge at 2A, 10A, and 15A. When you charge a battery at 15A, it may charge really quickly but it also increases the chance of blowing up your batteries. Plus they are not competition legal. but for driver practice they are probally great.
