I bought about twenty of the black and silver EEMB batteries (ER34615 in 2013) via eBay and to date have had no problems with them. Even if ten years is still too early to judge their reliability... I'm slightly off-topic, but I think the EEMB brand can indeed be trusted.

The black and silver EEMB batteries are not Li-MnO2, they're the same Li-SOCl2 chemistry as all the original battery-bombs. Personally I would not use those unless you're committed to checking and replacing them on a regular schedule.

While we're discussing battery replacements, what do people recommend for replacing 4.5V batteries? Do these really need to be 4.5V or will something less work? You could substitute 3x 1.5V alkaline batteries but then you'd be creating a new battery bomb.

I actually run my P630s and 6500s without a battery.

I have a shortcut to the Mouse, SetDate and Memory control panels in startup items, although there are better ways to deal with this - tools that set most PRAM settings during boot.

I use the same 3V Lithium batteries in my Macs that originally had 4.5V Alkaline batteries. Thread on this here:

Rayovac 4.5 battery replacement hack

I’ve previously used a 3 AAA battery holder to replace the dead Rayovac 4.5v “Computer Clock Battery” in a couple of my Macs. After some chat discussions I thought I’d try something different for my Performa 575, especially after noticing that in the Macintosh LC 520/550/575 Service Source doc...

I should have saved the dead 4.5V battery case and connector, but no biggie. So 3V actually works? That seems a little bit surprising, but is good news.

@tt those button cells were likely either alkaline or silver-oxide, both of which will leak, as evidenced by many older film cameras having corrosion in their battery chambers. With devices that use two 1.5 volt 357 (or PX76) style batteries, a better option is the CR 1/3N battery. Doesn't leak. For AA and AAA batteries, the Energizer lithium batteries are the best, but are rather expensive.
