so there''s quite a capacity penalty to high rates of discharge. A 150W inverter will take around 15A (assuming 85% efficiency) to deliver full power, 7A is only around half maximum load. The lifetime of a lead acid battery, before it wears out, is strongly related to its depth of discharge. That battery rates 260 cycles at 100% DOD, ie …

lead-acid battery (particularly in deep cycle applications). • is non-spillable, and therefore can be operated in virtually any position. However, upside-down installation is not recommended. ... Ah battery (@ the 3 hour rate)…(17 x 3 = 51). However, this is 100% of the capacity of this 51 Ah battery.
Lead-Acid Battery Cells and Discharging. A lead-acid battery cell consists of a positive electrode made of lead dioxide (PbO 2) and a negative electrode made of porous metallic lead (Pb), both of which are immersed in a sulfuric acid (H 2 SO 4) water solution. This solution forms an electrolyte with free (H+ and SO42-) ions.
For deep cycle batteries the standard rating is 20 hours. So, if a battery has a rating of 100AH @ 20Hr rate, then that battery was discharged over 20 hours with a 5 amp load. Starting batteries, on the other hand, are typically rated at 10Hr rate, because they are used faster, so the 20Hr rate is not as important.
Table 1: Battery test methods for common battery chemistries. Lead acid and Li-ion share communalities by keeping low resistance under normal condition; nickel-based and primary batteries reveal end-of-life by elevated internal resistance. At a charge efficiency of 99 percent, Li-ion is best suited for digital battery estimation.
The Chemistry Behind Lead Acid Batteries. When a lead acid battery is charged, the sulfuric acid in the electrolyte reacts with the lead in the positive plates to form lead sulfate and hydrogen ions. At the same time, the lead in the negative plates reacts with the hydrogen ions in the electrolyte to form lead sulfate and electrons.

The hydrometer offers an alternative to measuring SoC of flooded lead acid batteries. Here is how it works: When the lead acid battery accepts charge, the sulfuric acid gets heavier, causing the specific …
In high-rate batteries, there are many thin plates to allow for more surface area for quick generation of energy. In deep cycle batteries, the plates are thicker than those inside a high-rate battery because the energy-inducing chemical reaction goes into the plate and therefore needs to be thick to be able to handle the reaction.
The ideal storage humidity is 50%; Some sealed lead acid batteries have terminals which will start to rust in very humid conditions. Surface rust can quickly be cleaned away with sandpaper or baking soda mixed with water but if there is serious corrosion this will create an uneven surface on the terminal which could cause …
That looks like a lead acid battery with 2 cells. Luckily, assuming a relatively healthy battery you can get a rough idea of the charge level by just measuring the open circuit voltage..
