Review: Robot vacuum battery - Fit perfectly.
Review: Bad cells on arrival - Bad cells on arrival means the battery life is low and vacuum shuts off mid run, because it doesn't think it is low and then suddenly has no power left, so it can't even go back to the dock to recharge. I gave up on the battery after it did that 3 scheduled cleanings in a row, leaving it worthless to me.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Robot vacuum battery
*by J***N on January 14, 2026*

Fit perfectly.

### ⭐ Bad cells on arrival
*by G***U on November 7, 2025*

Bad cells on arrival means the battery life is low and vacuum shuts off mid run, because it doesn't think it is low and then suddenly has no power left, so it can't even go back to the dock to recharge. I gave up on the battery after it did that 3 scheduled cleanings in a row, leaving it worthless to me.

### ⭐⭐⭐⭐⭐ Large capacity Li-ion pack in plastic housing, useful for many purposes
*by J***T on October 25, 2024*

I got this battery pack, not to replace a weak battery pack in a vacuum robot, but to power my fish finders for ice fishing. Yeah, I know, that’s not what it’s designed for, but after replacing the connector the battery doesn’t know what it is powering, or even care. All lithium ion batteries lose capacity when they get really cold and it is cold out on the ice, so I have to have plenty of spares on hand. This pack looks to be well-assembled inside the plastic housing which actually works out better for me since that housing provides some extra protection for this pack when used like I’m using it. It took a while for it to reach full charge but it seems to be holding up well. I am unable to measure the actual capacity – the reported capacity for packs like this seems to be ever-increasing, likely due to the increase in quality of the individual cells – but I am happy with it for the limited time I’ve had it. I’ll provide an update after the upcoming ice fishing season if one is merited. The price at the time of my original purchase was only $15 – a truly incredible price for a battery pack of this capacity and apparent quality. So much so that I picked up another at that price. However, since that time, the price has increased to $33 at the time of this review, which is still a pretty good price for this pack.
