Review on Energup Li-Ion Replacement Battery For Dyson V8 SV10 Series - Compatible With V8 Animal, V8 Absolute, V8 Motorhead, V8 Fluffy Handheld Cordless Vacuum Cleaners - Replaces Dyson V8 215681 Battery by Mike Sutton

This is such a longer lasting than the OEM battery. I regularly use max power for portions of my cleaning and the OEM didn't take long, maybe 6 months, and it would go dead before I finished my normal use of it. Now when I plug it back into the holder/charger rarely flashes 2 of the 3 charging bulbs after use. Often just 1 of the 3 charging bulbs flash. I can also use max a lot more without worrying about running out of power.
