Lead-Acid batteries can indeed be charged after being dead. Commonly used in vehicles, these batteries operate on a lead-dioxide and sponge lead chemistry. They are robust and suitable for high drain applications. However, if allowed to fully discharge repeatedly, their performance may degrade significantly.
Can I recharge a completely dead sealed lead acid battery? Sealed Lead Acid batteries fall under the category of rechargeable batteries and if they are ignored, not charged after use, not charged properly or have reached the end of their intended life span, they are done.
To everyone’s amazement, new lead acid batteries can often be fully restored after dwelling in a low-voltage condition for many weeks. Other factors may play a role. A subtle indication whether lead acid can be recovered or not is visible on the voltage discharge curve.
In contrast, lithium-ion batteries allow for a quicker charge due to their advanced technology that facilitates efficient charging cycles. For example, if you attempt to start a car with a completely dead lead-acid battery, you may need to connect it to a charger overnight for a full charge.
According to Battery University, keeping a battery operating at a low charge (below 80%) can lead to stratification, where the electrolyte “concentrates on the bottom, causing the upper half of the cell to be acid-poor.” This can affect the overall performance of the battery and eventually lead to failure.
If you’re new to lead acid batteries or just looking for better ways to maintain their performance, keep these four easy things in mind. 1. Undercharging Undercharging occurs when the battery is not allowed to return to a full charge after it has been used. Easy enough, right?

batteries requires a charge. Often going into "trickle charge" mode. Not all charge cycles are equal. A charge cycle replacing 20% of a battery''s capacity versus a charge cycle replacing 80% of a battery''s capacity do not both count as the same charge cycle. We want to change focus to Service Life instead of Cycle Life
A healthy lead acid battery can take a huge charging current with no difficulty. 5/10/25 A are all fine. In fact, you can put as much current as you''re able, as long as your wires can take it, and the actual battery voltage does not exceed 14.2 V (for a nominal 12 V battery.)

For instance, in a lead-acid battery, the float charge voltage is typically set around 2.25V to 2.30V per cell, depending on the manufacturer''s recommendations. If the temperature rises, the float voltage may need to be lowered to prevent overcharging, highlighting the need for proper temperature management in battery systems.
Use a multimeter to measure voltage. A fully charged lead acid battery should read about 12.6 volts or more. If the voltage is below 12.4 volts, the battery may be undercharged.

Here are some common causes of sealed lead-acid battery not holding charge: Sulfation: This occurs when the battery is left discharged for too long, causing lead sulfate crystals to form on the plates. Over time, these crystals harden and reduce the battery''s capacity to hold a charge. ... 90 days money refund Policy and 1 Year .
Lead acid must periodically be charged 14–16 hours to attain full saturation. This may be the reason why wheelchair batteries last only 2 years, whereas golf cars with the identical battery deliver twice the service life.

The lead acid chemistry likes to be close as possible to 100 percent charge. A car battery will get f''ed up if you discharge it below 50% a few times whereas a deep cycle lead acid battery will handle below 50% for hundreds of cycles. But keeping a deep cycles above 50% at all times is crucial to keeping its lifespan up.
Voltage difference: Lead-acid batteries and lithium batteries have different charging voltage ranges. If a lithium battery is charged directly with a lead-acid battery charger, it may cause the lithium battery to be overcharged or damaged; vice versa, charging a lead-acid battery with a lithium battery charger may not be fully charged.

How long should a charge last on a charged car battery when the battery has not been used ? I know when I have bought new car battery, date stamp shows they were made/charged long time before. I charged relatively new, maybe 2 year old spare car battery recently, it was sitting in car disconnected & unused.
As low-cost and safe aqueous battery systems, lead-acid batteries have carved out a dominant position for a long time since 1859 and still occupy more than half of the global battery market [3, 4]. However, traditional lead-acid batteries usually suffer from low energy density, limited lifespan, and toxicity of lead [5, 6].
