DEWALT 20V MAX Battery, POWERSTACK, More Power More Compact, Rechargeable 5Ah Lithium Ion Battery (DCBP520)

The DEWALT 20V MAX XR POWERSTACK 5Ah battery has completely exceeded my expectations. The power output is noticeably stronger than my older packs, and the improved runtime means I can get through demanding projects without constantly swapping batteries. What really stands out is how compact and lightweight it is for the performance it delivers. The tools feel more balanced in hand, and the battery stays cool even during heavy use. Charging time is quick, and the overall build quality is exactly what you’d expect from DEWALT solid, durable, and built for real jobsite conditions. If you rely on your tools every day or just want more power and efficiency for home projects, this battery is absolutely worth it. Highly recommended!

These are awesome, the bottom grip base, balanced, smaller, lighter, and it does kick out more power. This even seems to last longer somehow. This was a good Black Friday buy.

Was hesitant on this one for the price, since same one is $179 + WA 8.5% tax. Received today in sealed Dewalt box. All markings on battery are authentic Dewalt. Easy to spot counterfeits as they lack top bar code and 2nd serial number. Mfg date on battery received same as order date 07/2025. Never opened and matched photo with authentic new model white led's which stay on for a second when activated. Also only charged to 1 bar which would be correct for a new unused battery. Unfortunately I have plenty of 5ah batteries but this one is for a specific Dewalt tool, or I would buy another one at this price.

Great battery for all 20v dewalt tools. It wakes up your tools compared to the regular xr batteries. I manly use it on my 3/4 dcf964 and it is a beast with it. It’s shorter than a normal 5ah xr but as wide as a 21700 cell 6ah. I like the one press for the battery indicator as well, stays lit up for a few seconds like Milwaukee batteries. It you use high power dewalt tools, you’ll love this battery

Seems to increase the power of some tools, not affected by cold as much as their other lithiums.

Perfect quality battery at a value price. The capacity of the battery is good, strong charge. Functions as it should

Very disappointed with this battery. After the return period closes, the battery will not charge. Bought this battery for $118 and after a few charges it stop charging. Very very very disappointed with Dewalt product.

Update: See below I purchased two of these and both have failed power indicators. No idea what level they are at. Fortunately, I also purchased the DeWalt hi-speed charger and keep it in the trunk of my Ridgeline. That has saved me from having to purchase additional batteries because the Ridgeline has an A/C outlet in the back, so I get a fully charged battery in about 20 minutes. I like the lightweight construction of this new DeWalt battery and in terms of how well the charge holds up under demand, I'd say it's pretty good by comparison 'By comparison', I'm referencing to the Waitley 2-pack 6A ($64.98) vs. the DeWalt 5A ($101.85). Doing the math here, you could essentially own/buy three 6A for the price of one 5A. Since they are both manufactured in China, I guess it boils down to this does the DeWalt logo imply their product is worth paying 300%+ more? Will it outperform its competitor manufacturer (Who knows? Maybe they are made in the same factory?) by a factor of three? I've used them side by side doing the same work and the Waitly performed about the same as the DeWalt. Only time will tell if the lifespan of one vs. the other becomes an issue. Update: The Waitley 6A batteries first time or two both seem to work pretty well, however, since then one of the two dies- runs out of juice doing the same grinding of cracks on a driveway. The second one seems one works fairly well, however, I noticed that it doesn't seem to have the torque of this DeWalt Powerstack, nor does it last as long doing the same work project. So yeah, maybe it is as the adage goes, "You get what you pay for" and the Powerstack is worth the xtra $$.

My favorite battery ever! So far, it doesn't matter what the job has been; this battery will last! Especially how light and powerful it is. It's a little wider, but I don't mind that.

Herramienta muy versátil

This battery is quite expensive for most, yet it delivers in performance and hopefully will last a couple of years more than a standard DeWalt battery. There was an issue with the delivery and seller was very helpful to make sure I receive the parcel.

Es lo que se describe. Falta ver como se desempeña en el trabajo.

Works amazing. Charge lasts all day and charges fast
