new used batteries

Recycling and recycling... I picked up a couple of deep cycle batteries from Randy in Ajax (referred by Troy). Made a donation to the South Pickering Amateur Radio club. He wouldn't take $50.

There's a large colour sticker on the side:
Advanced American Technology
Sealed Gel Technology
E.P.M. Products, Baltimore, MD 21226

For "Deep Cycle" continuous discharge/recharge and all "Marine Type" applications and "Float Type" Service.
Large sticker on top says:
Sealed, non-spillable lead acid gel battery F.A.A., C.A.B., I.A.T.A., and D.O.T. air transport approved.

Charge voltage limited to 14.1 volts @ 68°F.
Ventilate well. Do not store in an airtight container.
No. 8G22NF.
I tested them with my 12 volt car light. All good. I measured one for size.

height (including posts): 9-1/4 inches
width: 5-1/2"
depth: 9"

They look like this (without the bolts or Marathon sticker):

I found this photo over at Battery Mart. Looks like it is the same battery... Here's what they say about their battery:
  • Gelled electrolyte won't spill, even if the battery is tipped upside down ... or cracked open.
  • Length: 9 3/8 in.
  • Width: 5 1/2 in.
  • Height: 9 1/4 in. to top of terminals.
  • Shipping Weight: 39.75 Pounds.
  • Reserve Capacity: 77 minutes.
  • 51 Amp Hour @20 hour rate.
  • Group size: 8G22NF, NF-22.
  • Requires special gel charger to charge.
Looking forward to more power in the field. I wonder if I can link 'em in parallel...
