"Why is my car losing gas mileage?" it''s time for further professional diagnosis. Sudden drops in MPG are often caused by a much larger problem ...
To add, car batteries don''t last forever and this is the most typical way for them to die. Decades ago the typical lifetime of a car battery would be two years, today you can expect 7 - 10 years from a good Exide or Varta in your ''97 car, and possibly as little as two years again from the deep cycle type battery in a modern car with mileage-optimized charging and active …
With high power loads on a lead-acid battery bank you must account for the puekert effect. I would recommend: Follow @snoobler''s advice regarding charge voltage and current i.e. in lieu of battery specs: 28.8V - 29.4V (2.40V - 2.45V per cell). If you get a lot of gassing at the higher voltage drop it slowly towards the lower voltage in the range.
5 Lead Acid Batteries. 5.1 Introduction. Lead acid batteries are the most commonly used type of battery in photovoltaic systems. Although lead acid batteries have a low energy density, only moderate efficiency and high maintenance requirements, they also have a long lifetime and low costs compared to other battery types.
That was gonna be my first question too. I''m pretty sure he is because with a 40 amp load, his voltage drop is only a little over a volt. If they were lead acid batteries, it would probably be three times that amount. Lead acid batteries have a higher internal resistance than lithiums so any load drops the voltage much more than with lithiums.
2.1 The Coup De Fouet Phenomenon in Lead-Acid Batteries. The coup de fouet phenomenon means that when the lead-acid battery changes from a fully charged state to a discharged state, in the first few minutes, the voltage at both ends of the battery will suddenly drop sharply and then gradually return to a stable voltage to continue discharging.
A sudden drop in cell voltage at the beginning of discharge is due to polarization. All batteries lose charge over time when kept on an open circuit, which is termed as self-discharge.
The original battery that came with my W530 (a 6-cell 57Wh, manufactured around 2012) would drop to 5% from 15% or 20%. Probably because of battery age or abused by the previous owner. You could try have a separate Windows OS setup to run battery calibration using Lenovo Vantage as a desperate attempt to get a proper calibration.
Thermodynamics of Lead-Acid Battery Degradation: Application of the Degradation-Entropy Generation Methodology ... ECT entropy generation rate (red plots in Figure 4, right axis label) shows transients coinciding with sudden drops in voltage, starting at 0.02 W/K in the normal region and dropping to 0.003 W/K in the OD region.
The fully-discharged battery draws a high charging current from the power supply and overloads it, causing its output voltage to dip to the battery terminal voltage (close to 9 V) and rise as the battery charges. The sealed lead-acid battery, used for the demonstration, would already be as good as dead, with its terminal voltage far below the ...
Figure 1 illustrates the innards of a corroded lead acid battery. Figure 1: Innards of a corroded lead acid battery [1] Grid corrosion is unavoidable because the electrodes in a lead acid environment are always reactive. Lead shedding is a natural phenomenon that can only be slowed and not eliminated. The terminals of a battery can also corrode.
Lead Acid Battery Example 1. A lead-acid battery has a rating of 300 Ah. Determine how long the battery might be employed to supply 25 A. If the battery rating is reduced to 100 Ah when supplying large currents, calculate how long it could be expected to supply 250 A. Under very cold conditions, the battery supplies only 60% of its normal rating.

Generally, a well-maintained battery can last 3-5 years or more. However, factors such as deep discharges, overcharging, and exposure to extreme temperatures can reduce battery ...
The initial voltage drop at the switching on process in lead–acid batteries used as UPS may cause the breakdown of the battery and the failure of the external load when this operates within low fluctuations of the set-up voltage. One of the main components of the initial voltage drop is the overvoltage, whose effects can be considered more important than the …
It''s been very cloudy so I turned the dc-dc charger off and everything was fine until the around 40 amps had been discharged via the fridge then suddenly under 7 amp fridge load the voltage would drop from 12.4 to 11.6 and the fridge shuts down, the voltage recovers to 12.4v then the fridge starts again and cycle goes in.
