Hmm- isn’t the MSP430 idle draw something like 30uA?

Probably something like that. I don’t know if they bother with a deep sleep or not.

I’m sorry to destroy your Type 1/2 theory, but on my 4.0 Packs which are definitley 4A charge current is a Type 2 mark. It may be just a internal generation thing from DeWalt?

Well, then, I have no idea! :smiley: It would be wonderful if they’d document this stuff somewhere…

OK, so I’ve figured out the type thing (for real this time). It’s Black and Decker’s typology for different versions of things…all things. In this instance, the Type 1 battery is the first one developed for the so-called 20V tools, and Type 2 is modified from Type 1 by adding five cells. If you have any old B+D tools, look for “Type 1” on the sticker or plate. I’m looking at a vintage Canadian-made B+D drill right now, and it’s a Type 1.

Now you might be saying “But Russell already reviewed the new 6 Ah pack and it said ‘Type 2’ right on it, you idiot!” That is indeed true, but really, how does it justify a new pack type? It has the same number of cells in an identical configuration, they’re just fatter.

Still using a couple of 9180 battery packs bought in 2007 and they still run strong. They have been the most reliable and longer lasting Dewalt batteries that I have ever used.

I thought the Type 1, Type 2, etc referred to the revision of the product. So as they make incremental changes to the same product they increase the Type number. I’ve noticed this when looking for spare parts on the dewalt service net. Pick a DW705 for example and it has Type 1 through Type 8, and I have one that is somewhere in the middle.

Just another theory at least…

Hello.

I am very intrested in swapping my 18V NiCad battery internals, some XRP NiCad, some NiMH with the same internals from the older 18V NANO Phosphate and using them with my DC9310 charger and Dewalt 18v tools . Is that possible? Any tutorials on how? Any advice?
