Does Two 1.5 Volt Batteries Make 3 Volts

They said to remove the vent cover a half hour before use. I removed the cover and measured about a half volt. An hour later, 1.35 volts. Installed them, and now my vintage Luna Pro works perfectly! Great solution to replace an obsolete part!

I bought this because I purchased a flashlight that will operate on either a AA battery (1.5 volts) or a 14500 battery (3.7 volts) and this battery works very well in this application. It fit in the flashlight just fine and it holds a good charge for a long time. I have only charged it up 2 times since I got it but I am very pleased and I will by again.

Make any NP-F battery devove turn into a much longer way to power it long. Caution should be taken as not all devices support 16.6 Volts, ESPECIALLY CAMCORDERS and small lights, with one exception such as the genaray TrailBlazer, a NPF battery based light that accepts voltages from 7.4 to 18 Volts! So that's not a problem since the unregulated voltage that leaves this adapter is a maximum of 16.5V, being the same voltage that usually outputs from the main connectors or D-Tap ports. That means, that you can install a FULL SIZE 200 WATT-HOUR V-Mount battery on that and it will be powered until next century at 100%. Read the manual of the device you're using this on, make sure it supports 16.6 volts and more. I'm all about convenience and ways to hack powering things, and this product is one heck of a very cool and needed adapter! [I have received this product in exchange for my honest review]

. . . Two batteries at a time.

No need to worry about amps, volts or batteries overheating. It just works.

Have several types of batteries. Make them all work.

Two batteries are kept secure and handy.

Make sure you buy TWO of these if you have the latest EL’s. They work perfectly

Make a larger one for larger stupid transformers and batteries. You need these.

Make sure you have backup batteries for each camera you have. This one is terrific!
