So far so good. Only minor issue is that when it arrived, the (Braava 380T) mop complained - making multiple beeps and turning itself off then back on again to try to charge for a few more seconds before cycling again. This is generally a sign that the mop thinks that the battery is faulty - likely because the voltage it is reporting is below what the vacuum thinks is right. Eventually it will probably charge, but whilst it is doing so it will continue to make the error beeping (which is annoying) plus it will of course take longer to charge than it should. By holding down the three buttons for about ten seconds, the mop will stop making the error beeps and actually start to charge properly as indicated by the red light pulsing slowly. Note that after a little while it might start to complain again so you might need to repeat this a few times until it is finally fully charged.Having noted all that, once it had completely charged the mop ran for about 4 hours before it stopped with a red light and needed charging again - this is a decent runtime which makes me think that the battery is actually ok. When I returned it to the dock though, it started making the error beeping again. Hopefully after it has run through a few cycles this will stop, otherwise I guess I can live with having to press the three buttons to quieten the thing and/or put it back on charge before the battery goes flat.

The battery arrived in a generic brown cardboard box, it was protected with a bubble wrap pouch and a small set of printed ‘instructions’ which are just the usual battery warnings and cautions in a tiny font and a few different languages.It looks and feels well-made, it’s ultimately a 6 cell NiMH based battery pack with individual AA sized cells connected in series with strips of metal spot welded on, and the entire thing is covered with a protective heat-shrink wrapper and some card-like material on the ends to prevent shorts etc. It comes with a 5-pin Mini-SPOX 5264 connector on the end of the wire coming out of the battery pack that matches the connector on the compatible vacuums. Three of the pins are occupied, one for positive, one for negative and a third for monitoring what I assume to be a temperature sensor attached to the battery.The battery arrived charged to 7.756 volts which puts the state of charge on arrival in the ballpark of 80-90% which is a bit high and not exactly ideal for something that might sit around in a warehouse for a while. In the grand scheme of things it’s not a huge deal for short-term keeping it at nearly full but if it sits around for longer than 6 months it could start to become an issue.I’m not exactly using this for the intended application, so I chopped off the supplied connector and used my own for a project and the battery has had no issue supplying the expected voltage for a sustained period of time. Though my application isn’t exactly high power (UV LEDs for UV resin curing) and this is made for a vacuum, so that’s not much of a surprise. I’ve had no issues topping it up to full with a suitable multi-cell charger for RC car batteries and after resting for a while off the charger it reads around 8.4-8.7 volts as expected.I’m not certain how accurate the claims of the capacity being 4500mAh are considering this is cheaper than most 2200-3500mAh versions on Amazon, but I can’t say for sure as I haven’t put the claim to the test as I don’t have a suitable tester. It’s entirely possible that they’ve used 750mAh cells, so I'll give them the benefit of the doubt on the capacity, realistically it doesn’t really matter as long as the capacity at least meets or beats the stock battery which is 2200mAh for the compatible vacuums.No real complaints with this battery, it’s as advertised in size and works fine, it’s also reasonably priced relative to similar 6S 7.2V NiMH batteries for the same models of smart vacuums from other brands and vendors.

I got this battery as a replacement for our iRobot Brava 380T.The battery looks slightly different than it is in the pictures, but the dimensions and the layout of the adapter is exactly the same, and it fitted my hoover without any problems.Battery has slightly larger capacity than the original one, and offers similar working times.I am quite happy with this battery replacement.

Alles bestens!!
