I have never seen this mentioned in any guitar forum I have been on.

Never use Lithium Batteries or Rechargeable batteries in the pre-amp of an acoustic/electric guitar.

Here are the reasons:

[1] Lithium Batteries run hotter in most instances. Bad for pre-amps.

[2] Lithium Batteries put out more voltage, not much but enough to fry a pre-amp.

[3] Rechargeable batteries usually run a little less voltage that their throwaway cousins. This can cause your battery light to come on. Draining them faster.

[4] Rechargeable batteries when drained down enough dump all remaining power at once. Digital cameras and the like are designed to handle this. Guitar pre-amps are not.

I recommend a good brand of alkaline battery. Check it often. Pay a little more for a good brand. Your guitar is worth it. I have a young ladies guitar here that I am trying to fix because her father put in a rechargeable to save a little money.

Hope this helps someone.
