The product delivered fast and worked as advertised. Thanks, Joe Torrey
I repeatedly purchase from them and I am repeatedly happy.

As always, the products i receive from Battery Space are top-notch. I repeatedly purchase from them and I am repeatedly happy. The only downside is that shipping is expensive and slow. With that in mind I try to order early and get more stuff in each order.
one 14500 replace 3 AA in my DSLR

This is a very robust product. I am always carrying my Pentax DSLR with me. It is using a 4-AA battery to power up. After checking the wire connection, I easily/sucessfully illiminate 3 AA with this 14500 Li-Ion battery. One 14500 with one AA has the same voltage output as 4 AA, and they last as long as the normal AA configuration. Another nice thing about this combination is that I can always charge the 14500 with a smart charger and extending the usage time of the AA. Also, only one backup 14500 battery is needed when I go out for shots, instead of 4 AA. It has been one year now. I am very pleased with this product, and no sign of capbility drop of my 14500. Well done, batterspace.com.
