3v Batteries Leaked

I've seen several of these leak, the old NiCad's did leak occasionally.

I’ve never heard of any guarantee against battery leakage.  In 2015 I took this battery (made in 2009) out of a 2011 vintage loco.  Since then, I have replaced all batteries with BCRs.

Just because they wrote it in the manual, that doesn't make it true!

It’s interesting, over the years MTH offered both NiMH and NiCd batteries in their PS2 locomotives.  From my research, the charging curves for these are somewhat different, and while charging a NiMH battery in circuitry designed for NiCd will kind of work, it can damage it over time by repeatedly overheating the battery.  It’s the overheating which can cause these to leak electrolyte, I think.  

I’ve often wondered if this was a design consideration in the PS2 charging circuit.  

I can’t read it in the picture.  Is this a NiCd or NiMH pack I wonder.

The manual says it should not leak.  That's a while lot different than saying it won't leak.

Oh, WONDEFUL!!! NOT! Time to make a production run of super cap replacements.

Blue is NiCad, green is NiMh

Should not is not a guarantee.  Most do not leak.  Certainly do not damage like the older acid type batteries the would leak all over including externally as the liquid to run along the frame.  G

I saw two uses of the word "should" in that MTH document, but not the words "guarantee " or "warranty ".
