This is the sweet spot for me. This set is small but have enough power for most of my usage. I have 4 of these 4 AH and is my primary go to. At $10 per ah, is about the best you can get other than a price mistake.

Good deal, but can you trust Amazon?

The practice Commingled Inventory, which is a way of saying "we don't care if we sell counterfeits". So no, I can't trust scAMazon for that reason alone. I've been personally burned by this. Not worth it.

I got the pair from Lowes and they were marked Dec 2025. Other retailers have them but were reported had date stamp 2023 which makes it too old. Calendar cell degradation is real.

I get confused with all the different battery types. Can someone tell me what the difference is between the ones in this post and the ones at this link that cost a lot more?
