The FirstPower DC34 DC35 4500mAh Replacement Battery for Dyson Type B has truly revitalized my Dyson, delivering both technical prowess and consumer-friendly advantages. The installation process was a cinch, featuring an OEM fitment that required just one screw to be removed. This simplicity turned a potential headache into a quick and straightforward battery replacement. Post-upgrade, the impact was impressive – my Dyson's operating time noticeably increased, breathing new life into its performance (I also gave it a deep clean, de fluff and removed all that nasty hair from the rollers). Daily use hasn't posed a challenge; there have been zero issues with charging, including no overheating or failed charging instances. It's become a reliable power source, consistently delivering the performance I need. Before fitting this replacement battery, my Dyson refused to operate despite indicating a full charge. This replacement has turned the tide, giving my vacuum a second wind. Beyond the technical benefits, choosing to repair my Dyson instead of replacing it felt like the right move for both my wallet and the environment. It's a cost-effective solution with a sustainable touch, reducing electronic waste and extending the life of my trusty vacuum. As a friendly reminder, disposing of the faulty battery correctly is crucial – opt for responsible channels like your local WEEE disposal place and steer clear of the landfill. In summary, the FirstPower DC34 DC35 Replacement Battery is a dependable, environmentally conscious choice that has breathed new life into my Dyson.

The Dyson is back up & running. Very easy to swap out.

Good quality

Product came on time and was easy to fit. It 'charged up' with no issues and the additional filter was a nice bonus. Only time will tell how long it lasts but with a much bigger mAh battery I'm expecting great things. No complaints yet.

The original battery on my Dyson had given up and I was ready to scrap the whole unit when I came across this non-original version. I must say it has transformed my vacuum and as it's more powerful than the original Dyson battery, it even lasts longer between charges, so it's a win, win situation.

This replacement battery fitted perfectly in my Dyson.

Hi all. I didn't use the handheld as a heavy duty hoover, just used to hoover in kitchen/dining area etc but I bought this exact battery in January 2024, and it just died, so I guess 2 years 4 months isn't bad these days for any battery! I will buy another today, so hope this one lasts as long ;)

Work well. Will need to see how it performs over the next few weeks.
