Hi,
Lately my Dyson v8 battery is behaving rather odd. Within 1 - 2 min of use in power mode, it depletes a fully charged battery.
Seems to be a common issue (https://www.productreview.com.au/listings/dyson-v8/q-and-a) after 12 month of use. Mine will turn 2 years old in May 2019.
An original replacement battery from Dyson cost $90.
Have anyone purchased a third party battery from say ebay (https://www.ebay.com.au/sch/i.html?_from=R40&_trksid=p204767…) or Amazon? Whats your experience on third party battery? Any trusted seller to buy from?
Update 17 April 2019 - I rang Dyson directly as some have suggested. The outcome is a free battery and charger replacement. However the new battery and charger replacement will run out when my Dyson V8 warranty finishes on 15 May 2019. Thanks all for your input. Good outcome.
I had similar issue although I waited until the vacuum stopped working altogether. Rang Dyson within warranty period and they sent me new battery free of charge within a week or so. Now my Dyson works as new.
When it comes to lithium batteries, I'd always buy original though. Lithium batteries are fire risk.
