[Milsurplus] Batteries for Dynamotor Use

[Bruce Gentry]

Try golf courses, floor cleaning equipment shops, construction equipment 
shops, and truck garages for used batteries. They will probably not be 
sealed gel cell, but will last for many years in "retirement" service 
powering radios rather than golf carts, scrubbers, and staring diesel 
engines. Also, don't forget material handling equipment shops.  If you 
can find some large wet cell nicad batteries, they can last for decades 
and are often used in applications where they are replaced preventitively.

What types of batteries are you guys using to power your dynamotors? I 
have a nice set of Power-Sonic 210AH 12VDC AGM.. But sadly, they are 
nearing the end of their life expectancy (10 yrs)...  and cost a small 
fortune to replace.

I only have one dynamotor, for my ATD. Last I remember, I think it was 
about 44 amps in-rush at start up. Don't remember what the key down 
current draw is.

Best to just buy some cheap and dirty automotive batteries and replace 
them every few years?

Thanks, Durff, K4TQF
