7300 Replacement Battery Compatible with Dremel 755-01 Battery 3000mAh 4.8V for 7300-N/8, 7300-PT Pet Nail Grooming Tool (May not fit for Dremel 7400, 7500, 755, 750)

This worked great and fit into my Drexel perfectly.

Fits perfectly. Works great. Charge it before using.

Seems as well made as the OEM has plenty of power and run time would recommend

Although the housing LOOKS exactly like my original, it takes a little push/twist in order of it fit snug/correctly in both the charger and the Dremel. Slow and Fast modes seem to work fine with it. BUT what I did was find a video online to disassemble the original housing (this one disassembles the same way) and swap the new batteries into the original housing - Works great and now everything fits perfect too! NOTE you must keep an eye for +/- orientation of batteries as you replace them, since the housing is keyed. You can look inside the Charger as it has small +/- indicators so you can confirm its correct.

This battery charged and worked perfectly with my Dremel 7300 and is an excellent value for the money.

Works great

I bought this replacement battery for my old wireless Dremel 755-01; the original battery died a while ago, but I didn't know that was the reason it didn't work, and, believe it or not, I took it to a number of Dremel technicians to get it fixed, and no one ever determined that the battery was the problem! In fairness, it would be hard to tell whether the battery is charging or not, because given the old age of this device, the LED light that turns on while charging never -ever- turns off, so it is basically a matter of timing and lucky guess. When I looked for the original battery in the Dremel website, it didn't exist anymore, and I thought I might need to start looking for a new one. Now, the very good thing is that the Powerextra 7300 Replacement Battery has saved the day, and I won't need to purchase a new Dremel for a while, and the cost of this battery versus the whole new gadget is significantly lower, so it is a great choice!

Doesn’t hold a charge for very long. I bought to replace OEM battery which is over 12 years old. The 12 year old battery lasts just as long as this brand new one 👎🏼

Pese a otros comentarios que vi, ésta batería funciona como se debe, puede ensamblarse sin problemas

Funciona a la perfección.

Me sirvió perfecto para el dremel pet que ya está descontinuado.
