Best Battery for Active basses

Longest lasting and least likely to leak is what you want. I wish I could tell you which brand does that, but I can't.

I can tell you that every battery mentioned in this thread so far will leak with the exception of any lithium battery, and they might leak, but I don't know.

I did use nothing but Duracell in everything because I thought they lasted longer than Energizer. I've had Duracell cylindrical batteries AAAA (pen light) AAA, AA, C, & D all leak in some device. I've also had Energizers leak, so I don't know if there's a brand that's "leak proof".

I don't think I've had either of their 9v batts leak.

I know the lithium batteries are expensive, but with their shelf life being so long, they are probably the least likely to leak, and could be the longest lasting also.

I guess somebody needs to check with the Project Farm guy on YouTube & see if he's compared 9v batts….
 
Name-brands. Duracell or Energizer. I use lithium or alkaline. Lithiums sometimes fit a bit snug, but you can work around that if you stick a small piece of fabric or string under the battery when you wedge it in there, so you can pull on it to pop the battery out more easily. Don't use non-alkaline or rechargable batteries unless you want to deal with possible leaks or voltage weirdness. We're talking a buck or 2 per battery to have fresh power. Don't cheap out. I've never had a battery leak inside a bass, usually because I change batteries well before they die or could get to a point where they're old enough to leak. Also, remove the battery if you anticipate not playing a bass for a long time, or going into long-term storage. Preventive maintenance.
 
From the Ernie Ball FAQ:

"Average alkaline battery life is 6 months. We recommend Duracell batteries as replacements mostly due to size inconsistencies between battery manufacturers. Do not leave your bass plugged in when you have finished playing, as this will drain your battery faster. Battery life of course depends on how often and how long you play. When the sound of your bass becomes distorted, it's ready for a new battery."

gee that helps a lot....:thumbsup:
Forgive my Monday snideness.
IME most batteries are created equal and practically all will go dead when you forget to unplug your instrument cord from your output jack.
Fresh batteries are your best answer, and to get the freshest, you should look into venues that sell A Lot of batteries. I hate Kroger (or similar) prices, but happy homemakers don`t make special stops for batteries and likely will grab what`s convenient, resulting in more frequent restocking of batteries. I also feel better about buying name brands. I got tired of changing batteries so, as implied by my original posting, I got away from actives altogether.
In other words, I shoulda just kept my big mouth shut.

I use the regular Energizers. I don't trust Duracell anymore. I used to use their AA in my wireless mouse at home but over the last few years the quality has gone way down and they just don't last long at all. Cheap generic batteries perform better than Duracell IMO.

Yeah, but what's the best battery for metal? :)

Use two of them for added headroom.
