OPTIMA® Batteries Digital 400+ 12 Volt Battery Maintainer and Charger
We are not ready to call this price.
We check at least every 12 hours and hold a day-by-day record of what this cost — 10 days of it so far. Calling a price high or low needs 7 of those days and at least one change, because a range needs two prices: this one has not moved since we started watching. If it is still $149.99 on October 12, this box will say so — a price that has held for 10 days is an answer too.
