Watch this price

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 — 3 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 $106.56 on October 18, this box will say so — a price that has held for 10 days is an answer too.

Two 4.0 Ah batteries, 8 Ah in all: $13.32 per amp-hour at today’s $106.56. Every platform, per amp-hour
