Depending on how often I want re-count batteries,
the ## (counts) in the following list are often old.
AMP- APPROXIMATE SIZES
## VOLTS HRS (INCHES; see note below) COMMENTS
-- ----- ---- WIDE---DEEP---TALL- -------------------------------------------
0 24 6 7 1/8 2 3/4 4 1/2 Two glued-together 12V in series
7 12 17 7 3 6 1/2 Tabs-with-holes terminals
0 12 17 7 3 6 1/2 Bolt-screw-in terminals
21 12 7 2 1/2 6 7/8 3 7/8 Height includes terminals
7 12 3+
5 6 4.5 2 3/4 1 7/8 4 1/4
0 8 3.8 (New, but not yet measured)
0 8 3.2 1 1/2 5 1/4 2 5/8 IV-pump batteries; while bigger than a
"transistor" battery, they should power
a transistor radio a LONG time!-)
1 12 3? 2 5 7/8 3 3/4 Unusual rating
2 12 3 5 1/4 1 3/8 3 7/8 Height includes terminals
1 12 3 3 5/8 5 1/4 2 1/2 Height includes terminals
0 12 2.3 1 2 3/8 7 1/8 Look like laptop batteries; a little
difficult to attach wires to them
0 12 2.2 7 1 3/8 2 1/2 One has fuse & leads, one has leads
3 6 6 3 3/8 2 4 1/2
2 6 6 3 3/8 1 7/8 4 1/2 Height includes terminals
1 6 5.5 3 3/8 2 4 1/2
0 6 5 3 1/2 3 1/2 3 Three D-size cylindrical Gates cells in a
shrink-wrapped triangular-shaped pack
1 8 3.8 3 3/8 2 3 7/8
3 6 3.5 5 1/4 1 3/8 2 1/2 Height includes terminals
I usually also have "bad" shrink-wrapped Ni-MH and Ni-Cd PACKS in several cell
sizes ("A", "Sub-C", "half-AA", etc.), but you could make good packs from them
by disassembling and rebuilding them into whatever size & rating you need.
I once had a five-gallon-bucket of "D", "C", "AA", and "half AA" cells and 9V
"transistor-radio" batteries, but someone came all the way out from Kansas City
and took most of them! There were even some batteries that looked like
"transistor-radio" batteries (same connector, almost-exactly the same size,
etc.), but they were Li-Ion batteries with a slightly-different output voltage.
The "D" "C", "AA", and "half AA" cells read 1.4V+ under a light load and the
"transistor" (9V) batteries read 8V+ under a light load (but you should NOT
even THINK about using the latter in fire/smoke alarms because they ARE *USED*
batteries and MAY FAIL earlier than expected!), but they are mostly GONE now.
NOTES: "AMP-HRS" are taken from battery labels, but these are USED batteries,
so their actual AMPERE-HOUR capacities are probably somewhat lower!
"APPROXIMATE_SIZES" measurements were made with the terminals facing
up and close to me; WIDE is the length of the side close to me.
If you are curious, you can see my battery-charging/testing workshop area
here.
If you have a use for some of the above items, and if you'll
promise to recycle them properly when it/they finally "expire", then
contact me by email (W0PBV@ARRL.net) or phone (785-539-4448; Manhattan, KS).
It's "First come, first served", and "come" is the operative word!
Some miscellaneous WIRES and CONNECTORS are also usually available.
