A&T Batteries - sometimes called A&TB - is a "wholy owned subsidiary" of the Toshiba corporation. So you'll see these being called Toshiba batteries, as well.
We're not sure what the "H" designation means. Hopefully something like the terminal type, or something trivial like that. Else the LGQ86344 is:

| Misc. | "H" suffix means what? The cases are madel out of steel!!!! (they're magnetic) + tab is steel as well, but solderable Case seems soldererable as well (especially the - "disk" on the back)... is it plated? |
There batteries have sucky energy density - about half of Li Ion polymer batteryes - because of their heavy metal cases. Oh well.
Here are some nice pictures:
Closeup of the battery's label
Closeup of the battery terminals: disk is '-' (along with case), and the weird tab is the '+' terminal
Closeup (10x) of the '+' battery terminal and what I assume is the overpressure vent
200x closeup of the overpressure vent. Note that it's a very thin plate that has been spot welded on, with some weird circular thing... probably a very thin piece of metal (the burst disk)
