anybody might share private checks/experiences with utilizing a UPS with Lead Acid Battery day by day? and the way it performs over months? this can be a very particular thread/query concerning the “lacking knowledge” in these form of subjects. On this context it is extremely simple for readers to go off matter on what the query is-not about so let’s attempt to clarify.
I’ve learn tons of papers and articles on how rechargeable batteries work, variations between Lead Acid VS Li ion. I do know for positive batteries do want discharging, maintaining them eternally on a charging cycle kills them. The factor is essentially the most specialised articles go to extremes even speaking about room temperature, percentages of cost, and many others to the purpose that it does not sound like describing a battery, sounds extra like describing a child that should not go away the cradle. In case you have learn sufficient, you realize what I am speaking about. Such articles nonetheless do not present the lacking knowledge.
If you happen to analysis across the UPS (uninterruptible energy provide) and inverters + Lead Acid Batteries, additionally, you will discover a lot of papers and tutorials, setups, and many others, however none of them present the lacking knowledge.
What is the lacking knowledge? how the battery performs over months of use, actual life use.
In relation to li ion batteries that is simpler. Simpler to seek out detailed setups and the way lengthy it final, in reality 18650 have a higher background of reference in case you contemplate they energy your laptop computer, and you understand how successfully 4-6 18650 batteries have been capable of preserve laptops on for HOURS and this, repetitively over weeks and months. I can not discover such examples on Lead Acid. I feel I defined “the lacking knowledge” fairly wonderful.
Let’s discuss references:
- I’ve a photo voltaic setup utilizing 18650 batteries and I am fairly proud of it. It prices and discharges, so long as the batteries are balanced (every cell having the identical voltage) the setup lasts persistently the identical time day after day for weeks and months, fairly dependable. To me, this is rather like a comparability with a laptop computer utilizing 18650… cost, discharge and I get just about the identical runtime to maintain my stuff powered on.
- I’ve used this similar setup with Lead Acid Batteries however sadly these weren’t new, and confirmed degradation rapidly. I can not examine my private outcomes one with the opposite.
- I’ve used totally different UPS through the years each at work and at house. The issue is such setups when examined do final what they declare, as an example 30 minutes maintaining X laptop on, good. However the challenge right here is in most eventualities, over the subsequent months the battery won’t ever be discharged… and thus, after as an example 6 to 12 months, the identical setup with the identical laptop will solely work for five, 10 minutes as an alternative of 30. That is a loopy degradation in comparison with 18650… efficiency and chemistry apart, it is simply not a wholesome and realistically helpful state of affairs, as stated earlier than: batteries do have to be discharged sometimes to work correctly.
I examined on a few of my final UPS for infrequent discharges, as an example 1-2 monthly and the lifetime of the battery was nice in comparison with earlier Lead Acid examples. I’d get 30 minutes runtime persistently.
Constructed a TV Stand for purchasers utilizing a UPS and I used to be getting 45 minutes straight on a 24″ TV no downside. Utilizing the setup again and again with occasional discharges stored the battery alive, fairly neat and constant.
If I managed to clarify clearly and you bought the concept, you’ll perceive why I am in search of particular tales of getting and utilizing Lead Batteries day by day and report efficiency. That is one piece of knowledge that I can not discover on the internet (that I can belief) in comparison with 18650 batteries. Numerous individuals will report tales however the specifics are all improper: their batteries are stored eternally charging, or discharged to depletion with out utilizing a cost controller (going under the protected restoration restrict). I can not take these tales as reference, in any case these are tales of “how one can kill a battery”.
I am no wanting on how one can revive Lead Acid Batteries (truly I already tried diff strategies, it is not well worth the time). Discovered some tales on the internet concerning individuals on distant locations experiencing fixed blackouts and thus always needing a UPS, attention-grabbing sufficient they don’t complain on battery degradation, I suppose the fixed cost and discharge cycles preserve the battery on a special degree of capability (wholesome), however I do not know, these are outdated threads on boards and does not make sense to ask on to somebody who wrote one thing 3, 5 years in the past. But their eventualities appear one thing very helpful for reference.
I attempted to check myself on my setup, however at the moment I did not have the best data, and so… I by chance broken my Lead Acid Batteries, lengthy story. I am on researching and studying references. All I can say is, no less than on my private experiences, Lead Acid on my photo voltaic setup did not behave that totally different to 18650 besides on cost velocity. Efficiency was comparable however as stated, I by chance broken the batts so I could not preserve testing, how or why I broken them it is one other story.
Any info will probably be appreciated. Please chorus from sharing hyperlinks on how one can handle batteries, I am now properly documented on that, as stated it is the lacking knowledge that I am after, clearly defined on this publish.
