Topic: AA batteries? |

I just picked up a Katana Mini amp--7 watts, 4" speaker (not to play steel through, though :>).
It uses 6 AA batteries. Manual states alkaline batteries.
Question: would rechargeable AAs work in this device? Or do they just not have the oomph that regular single-use alkalines have? |

Rechargeable's are OK, just usually they don't last as long

Nominal voltage for alkaline AA batteries is 1.5 volts. Rechargeable AA batteries are generally 1.2 volts. Some products care more than others.

| Please don't but any Duracell AA batteries. I've had nothing but early corrosion from them with expiration dates up to 2025. Several items ruined. Even corrosion in the unused properly stored ones. |

Wow, thanks for that caveat, Larry.
I will only use this little lunchbox amp for busking, so I am not ordering the wall wart power supply: . . . which is $40! Ouch!
Thanks for the info, guys. Chris |

The TV studios at the network where I work use lots of the eneloop Ni-MH (nickel metal hydride) batteries in wireless mics. They hold their charge well and are said to allow 2100 charges. After several years we haven't replaced any cells. You do need a NiMH specific charger. They put out 1.2v and their discharge rate is even more steep than Alkalines, ie. they keep that rate steady until a shot time before depletion and then drop like a rock, unlike lead/acid batteries that put out peak for a while and then begin declining in voltage for a long period. As I recall, we haven't found any devices that can't use them.
We typically run the NiMH batts for an entire 1.5hr show and then recharge.

| Good info. Yes the Eneloop batteries also came up in a Google search and they look good. Thanks again, all of you. |

I quit buying Duracell for that exact same reason.

| They will work fine if you get the 2800 mha batteries. |

| I have a VOX DA-5 that runs on batteries. The DC input is 12 V, so I got a couple of battery holders (cheap on Amazon) for 10 aa batteries, and I use the 1.2V Eneloop rechargeables (2100 mhr). One set lasts for hours (not sure how many, but it's probably around 8-10). I carry an extra set with me in a second holder, just in case, and it's really quick to pop in the new set. |

I think that if I had to use a battery amp regularly, I'd buy a separate battery holder and use "D" cells to power it. Yes, they are heavier and cost more, but they will last about 10 times as long as "AA" batteries in any application.

Our band uses these Tenavolt Lithium rechargeable AA. They last alot longer than the nickel metal hydrides in my testing. You get them on Amazon.

No more Duracells here either. Bulk packs a couple times,,and more than half leaked in each pack.

| Duracells used to be my go to battery because they never leaked. Now they leak all the time and have ruined some of my very expensive equipment. Something changed.... I've started using Lithium batteries because they supposedly don't leak. |

I have had issues with all brands of AA and AAA non-rechargeable batteries for several years. For the most part I always remove the batteries except when using the equipment if at all possible. Many dollars wasted on damaged equipment.... Very frustrating!!!!!
