Go to AmazonWe 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: we have recorded 1 change.
One 5.0 Ah battery: $13.86 per amp-hour at today’s $69.29. Every platform, per amp-hour
Every change we recorded at Amazon

Price history
Tracking since October 8, 2026 · 3 of 7 days to a verdict
We do not draw a chart under 7 days of record. Over a handful of days every product is trivially at its lowest recorded price, and a chart that says so is worse than no chart.
| Price | Now | Lowest | Highest | Usual | Average | Days recorded |
|---|---|---|---|---|---|---|
| New | $69.29 | $69.08 on Oct 8 | $69.29 on Oct 9 | $69.29 | $69.22 | 3 |
