9V batteries sound and look like they should last long, but putting 6 1.5V batteries in series should last much longer.
9V batteries have a typical capacity of ~550 mAh, 1.5V batteries (even rechargeable ones) have a typical capacity of 2000~3000 mAh.
- bananabat 5y agoI'm glad my lil research has been validated. Last week I bought one of those adapter cases that accommodate 6 1.5Vs but have 9V terminals. Now how to tape that case to my little robot. And I don't know much, so thank you.
- andylynch 5y agoOf course 9v batteries are just six 1.5 cells in a rectangular pack- often they are even made of round cells like AAA, only much smaller.
- StevenWaterman 5y agoThey're actually AAAA cells!
