Don't buy these. I did save a bunch of $'s, however once I started using them I have had at least 8 of them explode, leak and corrode. I use them in power blinds and had 2 of the battery cartridges for the blinds destroyed....costing $20 each to be replaced. Move on...don't purchase these. To late to get my money back because I wanted these on hand for when the originals failed, which started in Jan 2018.
8 failures in 3 months once I started using them costing me over $40 to replace the damaged battery holders.
