So would you recommend or not? i got a sweet deal with some telecom battery tempting me. 100$ used for 3 yrs.A company I worked for many years ago used to do maintenance on a carriers mobile / cell phone transmitter sites. The sites were remotes on hills and mountains and usually grid powered but had a battery system if that ever went away which was quite possible if a cyclone hit the area. The batteries were maintenance free sealed lead acid of some type. From the rate at which staff were changing the battery at various sites I'd guess the carrier was expecting a 10 year life span.
They already have the space for the battery so anything that fits and lasts longer would be getting plenty of attention with the real differentiation being TCO across the achieved life of the battery.
I think if you can get a good deal and it meets your requirements then go ahead.So would you recommend or not? i got a sweet deal with some telecom battery tempting me. 100$ used for 3 yrs.
If you are in the market for lead acid batteries and don't mind the risk of wasting your money if it turns out the 2nd hand battery has been flogged to death I don't have a problem with that. If you plan on being able to use them long term I'd honestly step back and take a good look at lifepo4.So would you recommend or not? i got a sweet deal with some telecom battery tempting me. 100$ used for 3 yrs.
Quick update.
I got a price for 1 - 12v 100AH nearly fell off my wheelchair.
$1800 USD.
I guess I'll have look elsewhere.
One thing for sure. As this tech rolls out it'll one heck of lot cheaper.
Just like lithium iron... These Batteries will drop dramatically over the next few years.
As a resource fella I know lithium mining is exploding world-wide opening up supply.
I'll drag the leadacids in and out of the camps for now.
We are gonna see huge tech development coming.
It'll help all of us....
Please see attached charging recommendations and a state of charge chart. They don't work with all chargers. They need to be charged between 14.4 and 14.7V and prefer 14.6V. It is best if you can customize the charging settings. They can be charged at .25C. (4 hour charge time)yeah but something i notice the voltage is at 12.3 something i don't like it.
Thanks for your post! Would you have a recommendation for chargers to use when plugged into shore power? I have a customizable MPPT, and can dial those values in, but I was wondering if there is a “better” 112VAC charger to use on cloudy days or when the trailer is parked in the barn.Full disclosure - I distribute SiO2 batteries, but I am also a big fan of them personally. I use them in my "Solar Boler" and I leave them outside for the winter in Canada without a maintenance charger. They do fine.
Some background.
There are 3 manufacturer's of lead crystal batteries: Betta Batteries (Australia), Soneil Electronics (Canada) and Ev Solar (Germany). Green Rhino just signed a deal with EV Solar so I suspect that those will be available here soon. The prices are already a lot less than the prices quoted above. ... Betta and EV Solar have been more expensive mostly due to shipping. I know that Betta batteries are better prices if you are buying a large amount in banks for off-grid. Soneil Electronics has a lot more sizes for different applications at lower prices. They started out in 1994 making batteries for healthcare, material handling and janitorial uses. They expanded into larger sizes a few years ago but are not that great at marketing or direct sales. Lead crystal batteries are very popular in Australia, parts of Africa and Europe, but not as well known here in North America. I believe this is changing fast. Let me know if you have questions about how the batteries work and I will be happy to answer your questions.

CRYSTAL BATTERIES™ Safe and Powerful Performance Crystal Batteries™ are a unique technology that overcomes conventional battery problems by having a nearly solid-state electrolyte. This allows the battery to be discharged deeper, cycle more often, has a longer lifetime and can withstand extreme...leadcrystalbatteries.com
I have posted some info on charging and some of the research reports I have elsewhere on this forum.
