Lasted 250 days best in my review

March 8, 2021. Definitely noticed longer run times with this battery over its predecessor with lower mAh rating; which is logical. Have had no issues with charging (at least until now). However, the advertisement states 1000 charge cycles. Mine lasted 250 days (Walmart tells me I purchased this battery June 28, 2020), which means it only lasted a quarter of the advertised charge cycles.Nonetheless, I am here purchasing another because it's priced significantly lower than others which may not work as well and I find that even for 250 charge cycles, it's still a decent value. {shrugs shoulders}May 26, 2022. This battery died 3 days ago, giving me 14 months of use (about 420 charges). Again, that is far fewer recharge cycles than the promised 1000 charges, so I leave it up to you to decide if this is worthwhile.

Pros

Superior Lithium Battery with Better Performance - Once fully charged, allow your robot to run for 2 to 3 hours without returning to its base(varies between models). Our 5300mAH high capacity Li-ion battery compatible with Roomba 500, 600, 700, 800 series. Works much longer than the original battery and other cheaply made NiMH replacement batteries.

Cons
