Brushless motors require less maintenance as you don’t need to replace brushes on the motor **Q: How long does it take to fully charge the Dremel 8250?** A: Once the B816-01 battery pack is inserted into the charger a blinking green light on the charger will indicate the battery is charging. A solid green light will indicate a fully charged battery. Total charge time is approximately 95 minutes. **Q: How long does a full battery charge last?** A: The 8250 battery lasts approximately 12 minutes in heavy duty applications and 25 minutes in light duty applications. The estimates provided are based on average use and actual runtimes may vary. **Q: What’s the main difference between the Dremel 8250 and the 8240?** A: The 8250 features a brushless motor that provides more power, more runtime and more speed vs the 8240 brushed motor. **Q: Are the 8220 & 8250 batteries cross-compatible?** A: No, the 8250 is not compatible with Dremel 12V battery pack model numbers 875, 880, B812 & B814 which are intended for use with the Dremel 8220. The B816 12V battery pack is intended for use with the 8250 and not compatible with the Dremel 8220. ## Customer Reviews ### ⭐⭐⭐⭐⭐ 予備バッテリーが欲しい❢ *by K***様 on 2026年2月27日に日本でレビュー済み* 部品取り付ける用の軸が添付されていなかったので、付けられないですです。 パワーは、Dremel 4000よりあるみたいです。 予備バッテリーを探しているのですが、どこにも無くて困ってます。 ### ⭐⭐⭐⭐⭐ Powerful and comfortable! *by R***R on 2026年6月14日にカナダでレビュー済み* Well made, comfortable with lots of power. I especially like the new attachment for the cut off wheels. ### ⭐⭐⭐⭐⭐ Great replacement for my tired and old 3000 series *by D***H on 2025年10月13日にアメリカ合衆国でレビュー済み* My old AC direct drive brushed motor 3000 series is on it's way out (ton of high load use, the brushes are done, the stator has a crack, just overall done for. I considered another AC unit, but I found the 8000 series, which is driven by a 3s INR (I believe, may be IMR) and utilizes a brushless motor. I have around two dozen major 60v+ power tools that are driven with brushless motors, and I have designed/built numerous systems, vehicles, etc. using precision drive brushless, it's the way to go in almost every electric drive application. The 8250 (consequentially, 8150 and 8350, too) is a very good replacement. Delivering substantial torque under direct drive conditions is absolutely critical to a Dremel tool, and this system does the job as well as the AC unit. I would say it's an acceptable quality within the price range as far as both performance and general efficiency. Read on for the only perceived con; power supply availability. Battery use is... Okay, considering the power output. I will probably get one or two more batteries; one battery pack means you'll be significantly more likely to deep discharge it at high load, which is almost a worst case scenario for INR/IMR chemistry. While these are protected packs, it's extremely likely they will not enter cut off until around 3.0v/cell. (This is supposition, however, I am a credentialed EE and sys engineer with extensive design, manufacturing, and field work experience in DC systems with brushless drives of all kinds, large industrial applications, small RC vehicle applications, you get the idea. I have a seasoned "feel" for these type of systems.) Additional thoughts and comments:: I will probably build an external pack, maybe two, at around 6-8 amp hour size. The fact that the includes pack is rated at 3Ah is a bit suspicious, even for a top brand nameike Dremel. I haven't opened it yet, however, I would be entirely shocked if this pack consisted of anything other than three 18650 cells. It's likely managed by a displaced core BMS monitoring internal pack temp with a 10kΩ NTC, and individual cell voltages, reporting internal temp via the other contacts you can see on the battery (B+,B-,Temp, C1,C2; C1/2 are used as cell taps mid-cluster). This is sensible design, moving the BMS to the host device, as it makes a significant manufacturing cost reduction on the batteries. Conveniently, this also makes the packs an order of magnitude to rebuild once the cells crap out, or to build a big external pack, even one on a relatively short, DC/test point umbilical using a scavenged pack body. But I digress; this is circumstantial, and personal preference. If you need a DC Dremel specifically for confined space or otherwise where you COULD use an AC unit, this method might be inappropriate. In other words, if you need both tool accessibility and freedom from the AC cord, you should probably get one to three more standard energy packs, as you will quickly burn through the battery, both in energy consumption rate per use, AND overall service life of each pack. The pro of that is you can avoid deep discharge and increase pack life by as much as 50-60% in many cases. Anyways, do your homework on lithium ion, need be. None of this is anything new, it's just much more relevant with high power use modes on single cell series battery designs, and it's considerably more important still when you only utilize one battery pack. Overall, this is a suitable replacement for my high mileage AC source 3000 series, which says a lot. The price point is... Approaching prohibitive. The bundle doesn't really include anything of considerable value. I think it would be an immediate 10/10 if they included two batteries. The OEM battery MSRP is absolutely ridiculous considering the battery management is outboard, it's basically three cells, some wire, and terminals. I'll probably order some third party cheap-o packs, burn them out, rebuild one with quality cells (you MUST have a UHi resistive welder to do this, do NOT try to solder cyl cells, there is an extreme explosion risk), and use the terminal interface on the second with a considerably larger DC umbilical to use with half day projects.
