Hi, Some of the manufacturers use the "conductance technology" to determine the battery capacity (not the CCA), e.g. Midtronics. How accurate is this method? ... but any other brand will do the job. Also if the battery is a vented lead acid battery (the type where distilled water is required to top up the cells), then regular inspections and ...

I left the bike for 5 days and the battery dropped from 12.5v to 11.9v a 0.6v drop. The bike still started. 12 V battery 9.5 Ah sealed lead acid battery. I would like to calculate how long it would take to drop to 11 V or any other voltage for that matter so I know how long it can be left without charging it and still be able to start.

How To Charge A Lead Acid Battery
To charge a sealed lead acid battery, a DC voltage between 2.30 volts per cell (float) and 2.45 volts per cell (fast) is applied to the terminals of the battery. Depending on the state of charge (SoC), the cell may temporarily be lower after discharge than the applied voltage. After some time, however, it should level off.

$begingroup$ @php_nub_qq Just to throw a kink in things, back-in-the-day we didn''t have fancy MCUs and used hydrometers. The acid density varies significantly over the range of charged to discharged. I can imagine constructing a sensor design that could be read by an MCU that would be quite useful.

You can use the measured voltage to determine how much % charge a lead-acid battery still has (how much juice is left). To help you out, we compiled these 4 wet lead acid …
Battery Discharge Cut-off Control
This circuit prevents over-discharge of a lead-acid battery by opening a relay contact when the voltage drops to a predetermined voltage (lower voltage threshold). When the battery is recharged to a second predetermined higher voltage (upper voltage threshold), the relay contact automatically re-closes and power again flows to the load.

BU-403: Charging Lead Acid
Hi, I am making an adjustment to my house alarm so the 2 external siren boxes are powered by one lead acid battery (using in total about 25m of cable). Previously the siren boxes each ran on 6 D cells. I have a 6v 4ah lead acid battery, and a 3 stage (with float) 750ma charger which will be connected permanently to the battery.
