Does this product still function if fewer than 8 batteries are placed in it? I'm wondering if I would be able to get a range of different voltages.

There are batteries available that, instead of actually being batteries, are just wired straight through so that they work as spacers in applications like yours. Obviously this is just a plain holder for 8 cells in series, but a combination of up to 8 AA batteries and AA spacers will give you the variable voltage you're after.

It uses two triple A batteries, I see no reason why rechargeable AAA batteries wouldn't work. My unit seems to 'leak' electricity in that the batteries run down even when the unit is off. I 'fixed' this by taping a bit of plastic at the entrance to the battery door which I slide over the contact on one battery when it isn't in use, the batteries now last a long time.

According to the hype, you can charge up to 4, 12 Volt batteries at once? However, I could not get it to work?

send it back, i have purchased 5 units, no 2 are and have not functioned the same, only 1 has survived and with a rotation of 10 batteries, i am only lucky when 1 survives 1 hour

No. I tis designed to test off the shelf batteries. I personally have used it to test rechargables. It works on some but not on others. Have no idea why.

It seems to me that some of the batteries are "juicier" than others. If anyone knows a trick to bolster the voltage, please be sure to share with me. It's hawks that would benefit in my neighborhood.

Yes, it will work with any number from 1 to 4 batteries. They are connected in parallel.

Well, the manual says it works with a 6 voltage system, and i didn't check what my voltage was when i was using it. So the only way is to try to find out. Hope it doesn't blow on you.

Only if you do in series. If you connect in parallel the same way you take off the wires its still 12v no matter how many batteries you hook up.

I've used this tester on both 12v and 6v batteries but I've never seen an 8v battery. This is the best tester I've ever used and is well worth the price.

For a professional answer you will need to email ProMariner. But as far as I know the 20amp is only rated for three batteries at a time. But it would eventually charge the six batteries but it would be a slow process. I use the 20amp to charge two 100amp batteries on a Track Chair and it is fast.

Yes20v max and 12v max are the only batterys that work in that ratio.18v dont work in that ratio.But the reception aint good.

Sure. Can't imagine why not. This is a very high quality unit so it's not going to damage your battery with any weird voltage swings. I have five of them. One stopped working, which was my fault as I had hooked it up to a dead battery, but they were kind enough to replace it anyway. I would give them more that five stars if there were such a category!!

i just checked my ott lamp and i have only 3 battteries. maybe they updated the lamp. does the lamp itself have room for 4 batteries or perhaps it was a typo.

I've always used them with two cell flashlights. If the six batteries are in series (- of one battery against the + of the next battery and so on), then you'll increase the voltage but the overall power capacity remains the same. For example, two 1.5 volt batteries in series gives you three volts, but overall should have the same overall power capacity as one 1.5 volt battery. Six would be 6 x 1.5 = 9 volts. Now Having said that, I have recycled nearly dead batteries into flashlights with these LEDs and still get very useful amounts of light for several more months (where the conventional flashlight bulb would have become too dim to use). Hope that helps, Joe

I really wish someone would have done the math on this already. The pack holds 8 batteries. If you use alkaline batteries, which are 1.5v each, you get 8x1.5=12 volts. If you use nimh rechargeable batteries, which are 1.2v, you get 8x1.2=9.6v.The reason it shows 12v is because 8 normal AA batteries will yield 12v. The pumps can handle 12v just fine. We personally use rechargeables- we bought 16 rechargeable eneloops and just swap them every 3 days or so (my wife pumps exclusively). We found that we can stretch it to four days but beyond that the pump will start to die.

You would have to stack the batts and since you at 3 v now, I would not suggest doubling at 6v. I'd look for another battery. Not very dependable.
