Customer Reviews
⭐⭐⭐⭐⭐ Great value, works perfectly
by Tom R.
Bought this for my cordless drill and it works just like the original but at half the price. The 128VF version gives me about 2 hours of continuous use. Fit perfectly, no modification needed. Shipping took about a week to California.
⭐⭐⭐⭐ Solid battery, good capacity
by Mike D.
The 388VF version is a beast. Runs my circular saw for a good 45 minutes straight. Only downside is it's a bit heavy, but that's expected for the capacity. Would buy again.
⭐⭐⭐⭐⭐ Better than OEM
by James K.
Been using this for 3 months now and it still holds charge like new. The LED indicator is a nice touch. My OEM battery started failing after 6 months, so this is already lasting better.
