First you say "no, [not] at all" — it's never safe to fully discharge. Then you go on to state that problems happen "during charging" — which is a different activity. Finally you claim that a "deeply discharged battery have higher self-discharge", which at this point even my uneducated brain has to rule out as just plain illogical.
If you regularly discharge the batteries at a lower percentage amount, it will have more useful cycles than if you frequently drain the battery to its maximum DoD. Depending on the depth of discharge and operating temperature, the typical lead-acid battery provides 200 to 300 discharge/charge cycles.
The highest diagram they shown details a max discharge of 1C, they also mention in the handling guidelines to not let the battery voltage drop below 2.7V so you may need to do some voltage monitoring to be safe. Annoyingly thats the only mention I can find of discharging, so from that you could possibly assume the max discharge is 1C.
It is well known that Li-Ion batteries should not be deep discharged. But sometimes they do discharge deeply. Is it OK for the device to remain in such state for a long time (and recharge again only when the device is needed again after a year) or it should be charged back as soon as possible? In other words, the battery was discharged deeply.
“If a battery does become deeply discharged, special care must be taken during the subsequent recharge. With the aid of very low current, an attempt must be made to rebuild the basic voltage so that charging can then resume normally from 3 V,” says Heydecke.
Then charging causes a high amount of heat and a fire or explosion. Storing them "discharged" to ~3V with the device they were used in still preserves lots of energy in the battery. At 3V a Li-ion battery has almost no capacity left. In this graph two 800mAh batteries were discharged at various rates.
Refer to my article about my recommended chargers for LiFePO4 batteries. Conclusion. Figuring out at what amp you should charge your LiFePO4 battery is straightforward. Multiply the C-rate of the battery by the …
Allowing the battery to fully discharge can also be a mistake. This can cause sulfation and reduce the battery''s lifespan. ... For AGM sealed lead acid batteries, the ideal …
The batteries have protections for over and undercharging, check you battery model if it has these protections. If yes, it is safe. Li-ion batteries are very slow in discharging …
However, proper charging and discharging of batteries is critical to their performance and safety. This article will introduce how to charge and discharge batteries …
The batteries have protections for over and undercharging, check you battery model if it has these protections. If yes, it is safe. Li-ion batteries are very slow in discharging when not in any device, which may drain it.
However, if lithium batteries are not charged and left for a long time, they can still be pulled into deep discharge because the BMS also has a quiescent current. We recommend to always keep applications charged to …
The purpose of a battery is to store energy and release it at a desired time. This section examines discharging under different C-rates and evaluates the depth of …

It is safely impossible to drop an ideal battery to zero volts. A battery cannot go down to zero volts because of the internal chemistry. In a standard use, you cannot drop the …
No, it is not safe to discharge lead-acid batteries to zero volts. Fully discharging a lead-acid battery can cause irreversible damage to its internal components and reduce its …
A battery with a rating of 1000 mAh should be able to provide 1 amp of current, for 1 hour. Or 1/2 amp for 2 hours, or 2 amps for 1/2 hour, etc… C Rating – How Fast the Battery Can Deliver Its Energy Discharge rating, given …
The chemistry of battery will determine the battery charge and discharge rate. For example, normally lead-acid batteries are designed to be charged and discharged in 20 hours. …
To choose a minimum capacity battery use the 1C rate on small cells ie. Ah capacity remaining/ 1h and worst case impedance e.g. Vmin/IMax=3.2V/0.3A=≈10ohm load …
To choose a minimum capacity battery use the 1C rate on small cells ie. Ah capacity remaining/ 1h and worst case impedance e.g. Vmin/IMax=3.2V/0.3A=≈10ohm load and let that be 50x higher for 2% loss in …
The purpose of a battery is to store energy and release it at a desired time. This section examines discharging under different C-rates and evaluates the depth of discharge to which a battery can safely go. The …
For most RELiON batteries the maximum continuous discharge current is 1C or 1 times the Capacity. At the least, running above this current will shorten the life of your battery. …
Use a Battery Management System (BMS) to protect the battery from overcharging, deep discharging, and overheating. Is it OK to leave a LiFePO4 battery on the charger? It is …
Make sure you recharge the battery immediately after. An over-discharged Li-ion battery can catch fire or explode if recharged. So to prevent this, the charging circuitry will …
If you regularly discharge the batteries at a lower percentage amount, it will have more useful cycles than if you frequently drain the battery to its maximum DoD. Depending on …
Your battery usually has a sticker on it that will let you know if it is a Ni-Cd/NiMH or Lithium-Ion battery. If you can''t see your battery''s information there, try looking up your …
So, is there a rule of thumb for a max safe discharge current for (AGM in my case) Lead Acid Batteries? My gut feeling is that 300A for an hour on a 600Ah bank should be safe. But then …
It is safely impossible to drop an ideal battery to zero volts. A battery cannot go down to zero volts because of the internal chemistry. In a standard use, you cannot drop the voltage below 2 volts, even if you wired the …
$begingroup$ If a battery is s/c, the partially charged cells will drive the fully discharged cells in reverse. This is bad and may cause leakage, bursting, and, in theory, …
