Default Cheap 6v 4aH SLA Batteries


For those not frightened of carrying an anchor on their bike these SLA
batteries are really cheap.
Just got the "Supercheap Auto" flier and they have those million candle
power rechargeable lamps on sale for $9.99

For 10 bucks you get a 6v 4aH SLAB, a wall transformer, a crude battery
charging circuit inside the lamp, a 55watt 6volt halogen lamp and a
reflector. Jaycar currently have the same size batteries for $23. All
that stuff for less than the cost of 2AA 2.5amp Ni-MH cells.

Battery fits nicely inside a M16 ammo pouch.

Simple job to open the lamp up, extract battery, poke around for a
convient spot to drill a hole for the wires that were on the battery so
that they will pass out through the case and attach to the battery for
charging. Re assemble the lamp. Attach the charger to the lamp as
normal. Of course the light itself is totally useless for bike use.
After about 5 minutes the battery strains to keep the 55watt globe at
full brightness. Good for "spotting" possums in the top of the palm
trees.

Cant resist a bargain.

Cheers
Hugh

Pity the company caters to ****knuckles who think it is a good idea to
blast out their thump thump crap at 2:00am.

Or a very short term light that can be directed into the eyes of the
****knuckle who is about to pull out in front of you.

Err, 4Ah is not a boat anchor. Try 18Ah (6kg).

OTOH, I shudder to think about the forty, free 40Ah i considered collecting.

If the brands of the batteries are the same, then you can equate. Both
probably yum-cha cheep chinese anyway.

Wes components has 7Ah 12v SLAs for about $15 I think.

Yes sure - no problem. They have small spade connectors.
The correct size can be hard to source sometimes. A gentle squeeze
with pliers will close the standard size connectors up so that they are
tight.

Go find yourself 2 or more 'dead' NiMH laptop battery packs. Usually
only one or two cells in them are actually cactus and you can build up
a 12V pack for nix with better power/weight than an lump of SLA.

Is it difficult to test the individual cells, and what equipment is
needed? Source for "undead" ones? Too many questions!
