Replacement Battery for Dyson V10 Vacuum

Got a couple of these replacement batteries for the Dyson V10 vacuum. They're 25.2V Li-ion packs with 4000mAh capacity. One is still in the housing and the other shows the label clearly. They work fine with the Cyclone V10 series if your old one isn't holding a charge anymore. Just standard aftermarket parts, nothing fancy but they get the job done.
