Hey guys,

I bought a Battery Tender brand charger (1.25 amp I think) and I decided to use it a bit since I haven't been driving my Charger as much lately (so much work and home projects). I noticed that after I drive the car and park it, if I hook the charger up, it will charge for 12-18 hours before it reads full.

This is after a 25 minute drive or so with the ammeter indicating the battery is topped off (centered). Alt voltage is ~14.5V running.

Granted this is a trickle charger but is this "normal"? Can the charger top off the battery more than the normal charging cycle of the alternator?

Battery is a 2 year old Interstate - not a cheap one either. Otherwise battery and charging system seem healthy. Fires right up and she spins like a top.
