Keeping batteries in boombox?

[donahuest]

Just wondering if it’s good to keep batteries in your boombox when not using it?

I don’t like doing it as a rule.

As batteries deplete, a chemical reaction occurs internally which causes them to expand and leak. When you leave batteries inside a Boombox for a long time, it’s a good chance that you won’t remember or keep track of it’s charge level. So once it’s remaining charge drops below a certain level, leaking is virtually assured and the battery contacts will probably get destroyed by the leaking acid.

A few weeks ago I received a granddady of bboxes, Superscope CRS-152. look what I pulled out of it (note the expiration date):

Dead but in one piece! Acid fumed rusted springs a bit, but LCR cleaned them up nicely. On the other hand, Duracell AA//AAA batteries tend to leak acid into my remotes in less than a year! Take a look:

Exp.2008 - still OK; bought last year - already leaked!!! All "made in USA" but those which leaked also have some Chinese characters

Thanks. Looks like I’m going to take them out and put them back when I need them.

I found a really good Pioneer SK-909 earlier this Spring but the batteries must of been there from the 90s. Couldn’t see a date on them. They had leaked so badly I had to put gloves on and chisel them out almost. They were bulging out the plastic.

That is Horrible!!!

We have a very lengthy and informative thread here about rechargeables. Once these AAAs ruined my expensive-looking remote for Wadia, I am now going to follow the advice and switch to rechargeable batts

Hisrudeness. Man that’s pretty bad. I’m definitely not leaving batteries in my radios .

The leakage is more guaranteed when the batteries are in series and/or mixed with other battery types. The very nature of a standard non rechargeable battery and how it operates internally is exactly what Norm said. It builds pressure upon depletion of the battery chemistry and causes the seals to fail and whalla.

If I use it regularly I’ll keep em in for 8 years s if they are new to begin with. Otherwise take them out if not going to be used more than a few times a year. Not worth the ness.
Also don’t forget to take your clock batteries and back up batteries from your digital or boomboxes with clocks!

Hot weather also contributes to corrosion!

Thanks guys. Anybody know of some good “D” rechargables?

I'm using these - not cheap, but durable:
