Nice fit.
Ordered this to be a second battery for my impact I bought here on Amazon awhile back, but I could not find that impact brand here anymore. I was hesitant at first, but when I received it it fit like a glove and works well. Charged pretty fast too and has the power I needed. The correct mAh I was looking for too.

Charger and two batteries great find!
Arrived on time. I fully charged both batteries. Using one now and it works fine! Reasonably priced for 2+ charger.

Seesii replacement battery
It fits , it works as well as the original battery. Seesii wanted $50 for a battery . This company charged $35 for the battery and a charger. No complaints here.

Great battery replacement for a tool from a different brand product.
This battery was purchased as a cheap backup to the battery that came with a generic power washer I bought last year. The battery has held up well, its charge lasting seemingly as long as the original battery that came with the power washer. Given how expensive name brand batteries are (often 3X the cost of generics), it's nice to find a generic that holds up to heavy use. Highly recommended!!!!

Impressive replacement battery for OEM battery
Replacement battery for SeeSii Chainsaw matched OEM battery exactly. Delivered from Layger Imports within time expected, and follow-up from Layger was appreciated. Good public relations. Battery and charger are exact items and will make use of the Mini Chainsaw more efficient. Will deal with them and if needed re-order items such as this. Thanks.
