Question on Battery Tender
I bought a new Optima Yellow Top battery for my car about 6 or 7 months ago.... Its been fine, My OEM battery was also working perfect, but I needed the Yellow Top for racing (to run the fan & electric water pump) between rounds) I drag race the car.
My question is with the OEM battery... it was perfect when I removed it & I have it in my heated garage... so yesterday I thought it would be a good idea to put my battery tender on it just to top it off etc...
The Battery Tender I have starts with a flashing yellow light (while testing) then goes to a solid yellow while charging, and usually turns to green when the battery is fully charged.
Well like I said above the OEM battery has been sitting app 6 or 7 months & I put the tender on it (its a 2 amp charge) Its been on yellow now for app 12-14 hrs.. ?????
Does this sound normal.. I know when I race my car and run the fan and electric Water Pump a lot the battery still will get to full charge in 3 hrs at most (but I drive home so I'm charging the Yellow Top on the way home also....
Any thoughts on my OEM..should I take it and have it checked or could it have gone so low (charge) that the battery tender needs more than 14 hr to get it to full charge ??
Thanks..

A tender takes a long time to bring up a low battery. For that reason I use a regular charger to"fil up" and then use the tender to maintaine!
