Dynalite XP1100 battery recharge? Like a car?
I bought this system ages ago and haven't used it in a while. When I did use it, it was great; heavy but fast. The 2 batteries I bought are dead, I can't recharge them. I'm told they are basically motorcycle batteries. So, can they be brought back to life like a car battery? I didn't use them so much that I wore them out, I just stopped using them. BTW, big thanks to this post, I discovered that you can save $70 per battery over Dynalite's: https://www.modelmayhem.com/po.php?thread_id=524110 Sep 12 10 01:00 pm Link I dont know what chemistry this system uses look at the Manual to find out. Generally the worst thing for most batteries is to allow them to sit without being charged for extended periods of time. You probably killed it with lack of proper maintenance. Sep 12 10 02:35 pm Link Anything over a couple of years life is a gift anyway. Even the best car battery warranties tend to be "pro rated" after the first 2 years. It's the nature of the chemistry. Gelled lead acid batteries are interchangeable within a wide range. Commonly used in backup power and emergency lighting systems. Match the nominal voltage of course. Motorcycle and lawn tractor batteries can be used in place of them but have the acid spillage danger. There seems to be a general misunderstanding of how these things work and the tolerances involved. Minor differences in recommended charge rates and voltage don't have any practical effect. The batteries behavior is not constant across it's lifetimes in any case and also varies by manufacturer in any case. No one worries about changing between Duracell and Energizer AA's - they even come off the same production line in some markets. (measure the voltage in an automotive system - about 12V when not running - about 14.7 with the engine turning - all the fans, radios, electronics work regardless) The significant risks tend to involve Lithium and some other types of cells - charging must be stopped when "full" or they explode/burn. Usually involves built in fuses and temperature sensing circuitry as well as monitoring charge and discharge rates. Sep 13 10 02:42 am Link Robert Feliciano wrote: I have 2 of the Dynalite XP1100's. I paid $600 for 1 with a working battery (from an ad on Craigslist) and $425 for the other from a local Phoenix photographer that I knew wanted to sell it and the battery was dead...
