8.8 Where to find gel-cell batteries for bike lights
From: jt480401@longs.LANCE.ColoState.Edu (joe turk)
This is from the latest catalog published by All Electronics Corp. in
Van Nuys, CA (1-800-826-5432) :
VOLTAGE AMP*HR RATING SIZE (INCHES) PRICE
12 6.5 6 X 3 X 2 37.00
6 1.2 4 X 1 X 1 1/2 7.00
6 4.0 4 X 2 1/2 X 2 12.00
6 1.0 2 X 2 X 1 1/2 8.50
There's a few others that I've not listed. They also have 12V and 6V
DC wall transformers that put out 300-700 mA ranges; these run about $3
to $5 and make nice battery chargers.
For those of you who are running the 6 volt bulb in the Cateye halogen
light, the last 3 batteries listed above work great. They are very small
and suprisingly lightweight. The 4AH one fits nicely in a under-the-seat
bag and will give almost 5 hrs. of light with the 6V halogen bulb.
Other notes: You can find the Eveready 6V halogen bulb in any Ace
Hardware (Eveready HPR52, I think). Radio Shack sells Cateye look-alikes
(same manufacturer) for $7.00 vs. $20 for the real Cateye at your local
bike store (Part no. 61-2511).
These make fun electronics projects and promote bike night safety.

And yet another source for batteries is:
Mouser Electronics (located in Texas)
1-800-992-9943 to get a catalog
1-800-346-6873 for orders
They also have a 12V, 6.5 AH gel cell (Panasonic) with the following specs:
size: 5.95"x2.56"x3.86"
weight: 5.7 pounds
price: $29.90 (cheaper than All Electronics by ~$7)
They have several nice 6V units as well.

Here's another source for gel-cell batteries:

They have a good selection of gel-cell batteries ranging from 2.5 AH up
to 20 AH. I bought 2 of their 10 AH batteries to use in a lighting system.
Here's a small table listing some interesting specs about several of
their batteries. I generally left out all the batteries less than
6 or so AH. The AH/in^3 and WH/in^3 numbers I synthesized from the
others; hopefully I haven't made any calculation mistakes. The
catalog does not list weights.
