I was looking at the following battery charger for Lead-Acid/AGM 12V batteries between 35mAH - 45mAH batteries.
CTEK US 3000
I like the 4 stage charge method it describes but wish it had temperature compensation. For the most part I would be charging batteries with ambient temperatures between 45 deg F - 80 Deg F here in the North East. Out of that range the majority of the charging would be between 55 Deg F and 75 Deg F, which may not really warrant much compensation.
Sgt. Wookie mentioned a charger IC, the BQ2031 Lead-Acid Fast-Charge from TI. This, however is only a two step charger, but does have Temp. Compensation.

I am looking at purchasing a couple of these and was interested in what others might think about the charging methods.
