If they are lead-acid batteries, they can be thought of as "banks" each with about 1,500 charge cycles. Each time the battery is put on charge, that counts as a single withdrawal from the bank. But it doesn''t matter how much or little the battery is discharged (i.e. 20% or 90%) — it still counts as one withdrawal. So it''s generally better to let the battery …

If the Battery bubbles, that usually means you produce Hydrogen and Oxygen (some call it HHO). That''s explosive. That usually means you lose water from the battery. If it is a vented lead-acid battery, then the bubbling noise you hear is an electrochemical reaction that occurs while charging a battery.

Peukert''s equation describes the relationship between battery capacity and discharge current for lead acid batteries. The relationship is known and widely used to this day.
The voltage of a typical single lead-acid cell is ∼ 2 V. As the battery discharges, ... The reported Ah capacity depends on the discharge rate. A 100 Ah battery delivering 5 A is said to be discharging at a C/20 rate where C is the Ah capacity, and 20 is the depletion time in hours. However, the same battery may not be capable of delivering 100 Ah at …

You should be able to hear bubbling of H2 in a lead acid battery being created but watch out for ESD static discharges in an enclosed space. H2 gets easier to trigger above the lower explosive limit of 4%. Hydrogen is odorless, colorless and tasteless, so unless you can hear it, you cant see or smell it, but you may smell the sulfur-oxide gas which is often added to H2 tanks or from the ...

$begingroup$ This rule of thumb is problematic as a 12V lead-acid battery is actually 6x2V cells in series. If a 2V cell of a particular size was able to be charged at, say 0.5A, six of them in series (six times the capacity) should also be charged at 0.5A. Voltage and power will need to be higher but the current should be identical. Rules of thumb can be handy but it …
