## Customer Reviews

### ⭐⭐⭐⭐⭐ DC 34 battery upgrade
*by A***R on March 11, 2025*

So far so good. It fit my old Dyson DC34 perfectly and doubled the run time.

### ⭐ Does not hold charge after a few months.  Do not buy.
*by D***T on February 10, 2023*

DO NOT BUY THIS DTK PRODUCT, and perhaps avoid all DTK products!.I agree with all that was written in this review below. I metered out the charger and battery and it shows a voltage. but it doesn't work. I happened to have my old genuine Dyson battery around and installed it. Worked OK, but of course since it was replaced because it was old, the lifetime was short.Replaced type B for type B. Installed and Dyson worked briefly. Would not re-charge. Replaced old battery and all worked as before. Swapped in new again. Wouldn't charge. Checked everything installed cleanly. Check all connections with meter. Metered out charger and battery to ensure both working. Charger produces correct voltage and current. Battery appears uncharged. This battery is somehow defective or incompatible. The return period expired a week ago, so I'm stuck with it.

### ⭐⭐⭐⭐⭐ Fixed my non-working Dyson handheld vacuum
*by L***. on January 16, 2025*

I have a Dyson handheld vacuum that had gotten to the point that it would no longer hold a charge. I decided to try to find a battery to see if there was one available to save the vacuum from the landfill. I came across this battery and decided to give it a shot. Install was easy and the vacuum is working again. Super pleased.
