I just bought a new battery from Canadian Tire and charged it over night (9 hours) using a 1A trickle charger.

I had filled the battery according to the instructions and let it sit to get the air bubbles out before refilling and charging the battery. The chart told me to charge the battery approx. 8 hours for a 12 Amp-hour battery.

The battery read 13.25V right off the charger (6 am) and when I go home from work (4 pm) it was only reading 12.25V.

I was concerned, so I put the charger back on.... will have more readings soon.

Is this a normal for the battery to drop to this level so quickly?

thx
