Dusty Chalk Posted August 29, 2016 Report Share Posted August 29, 2016 Arise, thread, from the dead! These batteries have lasted for-freakin'-ever, but I now need to recharge them, and I can't find the charger I got. So question regarding the Pico Power -- is it okay to just use regular 9V batteries in it, until I can find or obtain another charger?

Dusty Chalk Posted November 30, 2016 Report Share Posted November 30, 2016 I want to get another pair of rechargeable batteries and rotate between the two -- Alkaline, Lithium, or NiMH? Do I need to make sure they can deliver a certain amount of amperage, or is there another spec I need to look at? Are there certain brands that are known not to fit? It's fairly tight in there. Powerex has 9.6V 23mAh, and 8.4V 300mAh, for examples. Are either disrecommended, the one that's over, or the one that's under? Tenergy and PowerAdd have some that are stated at 600mAh. @justin ...(or anyone else)...can you give any insight on what the different voltage ratings can do to the amp? I know it would never hurt to have more amps on tap, except that might also affect its physical dimensions, but I do not know what underpowering or overpowering the voltage will do. Wait, so the headamp site says: 2x 9V Alkaline included (40 hour life). Can use any 9V rechargeable batteries (NiCad/NiMH/Lithium) with an external charger (not included). Lithium primary cells (non-rechargeable) for a 120 hour life. So I'm confused about the alkaline, but it sounds like I can use anything.

n_maher Posted December 1, 2016 Report Share Posted December 1, 2016 The differing voltage will effect the overall theoretical headroom of the amplifier since they directly set the B+ of the power supply. But unless you're using the Power for something crazy it shouldn't really matter. I don't think you can really "over-volt" the Power with any of the options you've posted. Bottom line, I don't think you can put a "wrong" battery in there as long as it produces somewhere near 9V. 2 Quote Link to comment Share on other sites More sharing options...
Dusty Chalk Posted May 19, 2017 Report Share Posted May 19, 2017 So I got a couple of no-name pairs of 9V batteries, and I'm worried that they might be slowly breaking my amp, as they are slightly larger than the "MaximalPower" batteries provided by Justin. Are the MaximalPower the same as the iPower ones? They look similar from photos: Although...$30/each. Not sure I want to purchase yet another pair that don't quite fit at that price.

Dusty Chalk Posted May 19, 2017 Report Share Posted May 19, 2017 That doesn't eliminate the pressure on the cervix circuit board. 1 Quote Link to comment Share on other sites More sharing options...
EdipisReks1 Posted May 19, 2017 Report Share Posted May 19, 2017 Would taking the wrappers off the batteries help? Quote Link to comment Share on other sites More sharing options...
Pars Posted May 19, 2017 Report Share Posted May 19, 2017 Probably not much, plus being Lithium I would worry about someone mis-identifying them. Sent from my iPhone using Tapatalk Quote Link to comment Share on other sites More sharing options...
justin Posted May 19, 2017 Report Share Posted May 19, 2017 i bought ipower 520mah li-ion batteries a couple years ago and they fit. no idea about these 700mah Quote Link to comment Share on other sites More sharing options...
Dusty Chalk Posted May 19, 2017 Report Share Posted May 19, 2017 So I did something I probably should have done before I posted -- I held them up against each other, the ones that fit and the ones that don't quite -- their bodies are the same size, it's the snap-on connectors which are longer.

EdipisReks1 Posted May 19, 2017 Report Share Posted May 19, 2017 How much is it flexing connections on the board? Quote Link to comment Share on other sites More sharing options...
