Is it bad to undervoltage a 12 volt lead acid battery?

I had a heated discussion with a few colleagues today revolving around how low of a voltage was alright for 12 volt lead-acid battery; they were in the opinion that the low voltage warning buzzer and ultimate automatic shutoff was annoying and a safety risk.

Can a lead acid battery be replaced with a lithium ion?

The substantial benefits that Lithium Ion technology offer over lead-acid technology means that using Lithium Ion batteries is becoming an ever more popular choice. When considering replacing an existing lead-acid battery bank by a Lithium Ion battery bank one needs to take a couple of things into consideration.

What is the charge voltage of a lead acid battery?

The discharge voltage curves may be depressed by as much as 0.5 VDC from those shown on the graph. Charge voltages will be elevated by as much as 0.5 VDC for a cold 12 Volt lead-acid battery. Lead-acid Internal Resistance and SOC In lead-acid cells, the electrolyte (sulfuric acid) participates in the cell’s normal charge/discharge reactions.

When to change charge voltage of lithium ion batteries?

The charge voltage of the battery bank needs to be checked and possibly changed. Where low charge voltage will result in incompletely charged batteries, overly high charge voltage will potentially push the Lithium Ion batteries outside their allowed operating conditions. Battery monitoring needs to be shunt (Ah counting) based, not voltage based.

Can a lead acid battery be replaced in an RV?

Basically, they don’t recharge as well as flooded lead acid batteries. The process to recharge is much slower, and if they are overcharged, it can cause permanent damage to the battery’s cells. However, gel type batteries are being largely replaced by another kind of VRLA incorporating a fiber glass Absorbed Glass Mat (AGM).

What’s the voltage of a lead acid battery?

Secondly, the Voltage of a Lead-acid battery is fairly steady for most of its discharge, but at the end, its voltage rapidly decreases. . . So if you discharged it to say 9V at would not be much further than about 10.5V BUT you must rapidly take it off that discharge and start to recharge it. . . . .

What happens if your car battery is low?

A weak battery or low system voltage due to a charging problem can cause all kinds of havoc with the on-board electronics. For example, low voltage may cause the airbag or ABS warning lights to come on. The turn signals may not blink normally when the switch is flipped to either side.

What to do if your alternator is over charging the battery?

Ask an assistant to start the engine and hold engine speed at about 1500 RPM. Measure voltage across the battery with your DMM. You should get 0.5 to 2 volts higher than base voltage. If you are getting more than 2 volts above base voltage, most likely your alternator is over-charging the battery or the battery is faulty.
