Kastar XV11 Battery (2 Pack), Ni-MH 7.2V 4400mAh, Replacement for Neato XV-11 XV-12 XV-14 XV-15 XV-21 XV-25, XV Essential, XV Signature Pro Robotic Vacuum Cleaners Neato Battery 945-0005 205-0001

Replacing the batteries on my ancient Neato XV Signature was fairly simple, and injected new life into the old robot. These seem to clean for longer than the original batteries when it was new. Hopefully, they'll have a long service life. I've gotten Kastar batteries for several other devices and have been pleased.

Vacuum works like a champ now.Simple removed old and the replacement snap right in. I would recommend to charge fully before first use. Runs better than new, amazing power.

They lasted 1 year before it won't run over a minute. Don't buy these

Worked for less than 2 months

Installed the new batteries today and started the calibration process of 3 complete charge/discharge cycles. First charge lasted about 50 minutes. On the second cycle, my XV-21 ran for about 100 minutes before returning home to recharge.Very impressed with this run time, which is substantially better than the original batteries supplied with the unit.Neato does warn against using 3rd party battery packs which, they say, could damage the unit or void the warranty - since my XV-21 is already 6 years out of warranty, I was willing to accept the risk.So far very impressed with these batteries - it does remain to be seen however, how good their lifespan is, before they start to lose their run time and storage capacity.UPDATE :A year or so later and the vacuum can no longer do a full circuit without returning to dock at least twice to top up its charge. I thoroughly cleaned and checked the vacuum and charging dock and could find nothing wrong. Also measured voltages at charger and individual battery units and reported my findings to Kastar via their online portal, with a view to warranty replacement. A month or so later and I have received no response from Kastar - rather disappointed!!

Installed in minutes and back to business. I don't really sit around and watch the little vac work, But it appears to get a lot done so the batteries must be working well.

We've had to replace batteries in our "old" Neato a number of times now, each time the replacement batteries seem to die out after several months of use. These new batteries injected new life into our Neato, and hopefully will last longer than the last batteries we bought... Time will tell, and fingers are crossed...

I write on the batteries when they were installed. The last set of batteries barely lasted 4 months and, when fully charged would only vacuum 1 hallway. Do yourself a favor and order a different brand. I've had batteries last almost a year and would do 2 rooms before needing recharged.
