This 8000mAh ZKpilse battery is a powerful and reliable replacement for Milwaukee 18V tools. It fits perfectly, offers long runtime, and has no memory effect so you can recharge anytime. The built in LED indicator is handy, and safety features protect against overcharging and overheating. Performs like the original at a much better price. Great value and highly recommended!

These batteries are an excellent and cost-effective alternative to the original OEM versions. They hold a charge well and deliver reliable performance for my needs. The fit and finish are also impressive, matching the originals in quality.

These are a fraction of the price you would pay for the actual Milwaukee batteries. They work just as well and hold a decent charge

These batteries are absolute beasts! I use them daily with my Milwaukee cordless tools and they easily last through a full day of work. The 8.0Ah capacity really makes a difference—plenty of juice for heavy-duty tasks like grinding and hammer drilling. Great value for the price, and they hold up just like the OEM versions and I was skeptical about third-party batteries, but these surprised me. They fit all my M18 tools perfectly—especially my 2646-22CT grease gun and my 2641-21CT caulk gun. Charging time is comparable to the original, and I haven’t noticed any overheating or issues. Solid buy and I upgraded from 5.0Ah batteries and the difference is night and day. These 8.0Ah batteries let me work longer without stopping to swap or recharge. I’ve used them for my cordless impact wrench and reciprocating saw with zero problems. Highly recommended if you're doing long projects or job site work and I use a range of M18 tools on my farm, and these batteries have been fantastic. They're powerful, reliable, and they don’t cost a fortune like the Milwaukee-branded ones. I’ve been using them in my 2646-20 and 2646-21CT tools with no compatibility issues. Great investment

If you’re using Milwaukee tools daily, this replacement battery is a solid investment. It charges quickly, holds power for a long time, and delivers consistent performance even under heavy load. Build quality feels just like the original—no overheating, no power drop-offs. Whether you’re on the jobsite or working in the garage, this battery keeps your tools running strong all day. Highly recommended for pros and serious DIYers.

These replacement batteries work great with my Milwaukee tools. Long-lasting power, charge quickly, and fit perfectly. Great value for a 2-pack — just as good as the originals!”

I have had these batteries for 2 months. 1 of them is completely dead already. Flashes green/red on charger. When they were working, they would overheat very fast. You get what you pay for. Going back to OEM!
