Great batteries for the clock drive in your telescope
This is not for everyone but if you have a Celestron telescope like I do you will need these batteries for the clock motor. They are a but hard to find but here they are. The seem to last a very long time.

Great exact replacement
These batteries are the exact replacement for my present device. They came with most of a full charge ready to use. My device now works like new. I highly recommend these batteries for high density power needs and exact replacement.

Same part number as on old battery.
Exact replacement for my rechargeable flashlight from the 80s. Part number the same as on old battery.

They actually are newly manufactured.
they came pretty quick, i think 3 days. They work. All batteries were 2.2v when i got them and hold their charge. Date code on the bottom of the battery is in a different font than the original batteries these replaced (from 2009) that these replaced, but no big deal, could be a different newer machine, who knows. my only gripe is the price change a day after i got mine from 14.95 to 12.00. Kind of lame.

Exact replacement for the old strobe tach
Had picked up an old strobe tach at an auction and it worked great when I got it didn't have a charger with it. By the time the batteries died and I finally got a charger, it was too late. I had killed the batteries. Took it apart and was surprised to see sealed lead-acid batteries. Had considered changing to a different battery type but that would have required some re-engineering of the charge circuit and that is outside my list of skills. So found these and replaced the 3 cells and all is good. Will be able to keep them charged with the cheap multi-voltage charger I picked up.

Replacement for worn out batteries in a Quantum remote camera flash power pack
These are standard batteries in a Quantum flash power pack I have had for about15 years or more. when ever they get worn out (every 4-5 years) I just get these and replace them. This saves a huge amount of money by doing it myself rather than sending back to the company for them do it. It is just a simple unplug and plug in swap. These have plenty of power and don't have a memory or over charge problem so can leave plugged in ready to go.
