Anyone wondering if these work in dremel 8250, the answer is yes. I can’t speak to longevity or the quality of the cells inside. But they are priced well, appear to be made well, and work flawlessly in my dremel 8250. Also the company Calihutt seems to specialize in third party batteries and appears to have good reviews across thier products. I will probably pick up a kobalt 24 v max just to have a third battery because I see they are only $30 and well reviewed. Anyway back to the product in question. Yes well made, priced well, works in dremel. Company seems to have a good warranty which is also a plus. One caveat to potential dremel owners, the keyed tab is on the opposite side of the terminal. It will still insert and work just fine, but it won’t work on the stock dremel 8250 charger. The key gets in the way. I have other chargers and it works fine in there. What I did was just cut off the key with a cutoff wheel. Took two seconds. I didnt need to because as I said I have other chargers that work, but I’d prefer if all my batteries worked across all my chargers. I probably voided any warranty and that’s ok with me. If not spend $14 on a Bosch charger. I bought a really neat one that is super compact, slows you to use usb c, and can be used as a power bank if need be. It doesn’t have any key so all batteries no matter which side the key is on will work. The reason I got it was specifically to be able to use usb c instead of ac power. The added power bank functionality is nice to have but I’ll never use it. So yes these batteries are good so far and work in dremel 8240,50,60. Seems to be good quality, and good company, and a fair price. For reference one dremel battery is $70! No thanks. I did buy one official spare and that’s only because it was on sale for $53 which is still expensive for one 3ah battery. Now I have 4 total and am set. 2 oem, 2 third party and two chargers.

Item arrived fast and pre-charged. Fits perfectly in Tool. We definitely order again.

Great deal and work well.

Worked well with the tool and seem to last on a charge a good amount of time.

Holds charge better than 2.0

Worked on a 15 year tool

Have purchased 4 of these batteries. One stopped working after 6 months. Would no longer take charge.

Great product. Perfect fit and function.

Características exactas, buen material, embona muy bien, hasta ahora funciona perfectamente.
