I always buy once cry once, but I thought I try for a $150.00 savings and bought a Vanon 9.0 A/H battery for $60.00 to replace a Milwaukee @$249.00 and it sucks. Works about 5 minutes in and it's dead.
I had to write Vanon multiple times trying to get service even though their website gave a number for customer service that does not work. After a few days they wrote back. They wanted pictures of the battery ( I can understand that) I also sent them the purchase order number . They then wrote back and wanted a video sent to them showing how long it lasts before they can send me a return authorization. I wrote back and told them I wasn't going to do that for them and they finally sent me a RMA.
It'll cost me $20 more to send the piece of crap Vanon back to get a refund. If I ever did return it, I'd probably lose another 20 bucks shipping doing so. I'll take my loss and dissect it to see what junk batteries are in it.
Don't do business with this company, their batteries are JUNK!
