Lead acid battery
A lead/acid battery contains sulphuric acid which combines to the plates when discharged. After time, this lead suphate becomes stabilised and is more difficult to dissociate into lead and sulphuric acid so capacity is lost.

How Long Can A Car Battery Sit Unused Without Being Charged?
Lead-acid batteries, common in most vehicles, can degrade faster than newer lithium-ion batteries. Lead-acid batteries typically lose charge at a rate of about 5% per week when not used. In contrast, lithium-ion batteries have a slower discharge rate, which can be as low as 1-2% per month.
What is the shelf life of a sealed lead acid battery?
A SLA (Sealed Lead Acid) battery can generally sit on a shelf at room temperature with no charging for up to a year when at full capacity, but is not recommended. Sealed Lead Acid batteries should be charged at least every 6 – 9 months. A sealed lead acid battery generally discharges 3% every month. Sulfation of SLA Batteries
Why Your Sealed Lead Acid Battery Won''t Hold 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. Using a charger that is not designed for sealed lead acid batteries can damage the battery and reduce its overall lifespan

Battery Failure Mode: Negative Plate Sulfation
When a lead-acid battery is left to self-discharge (in storage or installed but seldomly used) or is exposed to excess and repeated high-rate charging (such as is the case with Start-stop vehicles), a point can be reached where the reaction at the negative plate that should convert the lead back to active material (PbSO4 back to Pb) can not accommodate all of the charging currents.

A lead acid battery can be stored for at least 2
Can a car battery sit uncharged for two years?
If a conventional lead acid battery goes dead, the plates can sulfide up and lose their battery-ness. they get coated with a sulfur compound and won''t conduct no mo. Either that or they short together, can''t remember. Sometimes you can rejuvenate an old battery by replacing the acid with new stuff.

Why lithium iron phosphate (LiFePO4 ) batteries are suitable for
Unlike lead-acid batteries, LiFePO4 can be left in a partially discharged state for extended periods without causing permanent reduction of capacity. LiFePO 4 can have low self-discharge rates (unlike lead-acid which will go flat quite quickly if left sitting for long periods). LiFePO 4 do not suffer from thermal runaway. VRLA charge rates and
What happens when a lead acid battery is
When a lead battery sits below 50% state of charge (about 12.10v for a 12v deep cycle battery), the rate of growth & accumulation of lead sulphate crystals increases substantially.
How Long Can A Deep Cycle Battery Sit Without Charging?
Deep cycle batteries, including lead-acid and lithium variants, can become damaged if stored uncharged for extended periods. Lead-acid batteries typically lose charge faster than lithium batteries and are more susceptible to sulfation. Temperature and humidity also play a crucial role in charge retention.
How long can a car battery be uncharged before it is ruined?
I can say this with confidence: any sealed lead acid battery no rated for deep discharge will incur some level of permanent damage if it spends time below 10 volts open
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.. In ideal circumstances an SLA battery should never be discharged by more than 50%, for a maximum life span no more than 30% (to a 70% state of

What happens if a lead acid battery is flooded?
If lead acid batteries are cycled too deeply their plates can deform. Starter batteries are not meant to fall below 70% state of charge and deep cycle units can be at risk if they are regularly discharged to below 50%. In flooded lead acid batteries this can cause plates to touch each other and lead to an electrical short.
