My battery temperature is round 30 degrees Celsius while sitting attached to my laptop computer on AC energy neither charging nor discharging. Many laptops allow you to set them so they don’t charge to one hundred% while hooked up.

Robert - Sealed lead-acid batteries were conceptualized by marketing individuals, not engineers. Sealed lead-acid performance and longevity are unpredictable. In case of sealed lead acid batteries storage for six or extra years, what could be the higher technical technique, irrespective of the money. The forty% SOC value is a compromise - li-ion batteries age even much less at zero% SOC, but you don’t need the battery to go so low that it goes into sleep mode and is dead. Dinh - I assume you imply lead-acid that has come off the meeting line, by no means been filled with acid, also referred to as unformed.

Without understanding what kind of lead-acid technology, I am guessing. The Li-Ion battery ought to be good for up to 500 cycles before it begins to lose its capacity, depending on its model and quality.

I lately used batteries that came off the assembly line in 2002, have been stored in storage all this time, crammed them, fashioned them and they labored simply fantastic. Best approach to vharge NiCad batteries fir battery oowered tools and best way to charge Litham Ion for same instruments Also, finest approach to retailer the above for severa months ;lrior tous ans store once more Thenk You.

If you don’t hold your batteries charged in this method, you will be kissing them goodbye. From what I’ve learn on the internet, it appears to be that it should contribute tremendously to plate corrosion from an excessive amount of boiling (oxygen release) and that it’s not an excellent factor. I’ve determined not to maintain my battery on float charger whereas not using it because it doesn’t seem good to me.

Kevin - You appear to be saying that your batteries were not totally charged whenever you stored them. Modern lead-calcium alloy grid batteries can develop what is understood within the commerce as “open circuit” when left like this.
