The following, if done correctly, will tell you more about the condition of your battery than any "anecdotal" history ever would. Use a digital voltmeter and a temperature compensated (Floating Ball type or Gauge type) hydrometer for the testing, and a BatteryMINDer charger maintainer to avoid future problems with battery sulfation.
Before starting to charge, first detect the battery voltage; if the battery voltage is lower than the threshold voltage (about 2.5V), then the battery is charged with a small current of C/10 to make the battery voltage rise slowly; when the …
Watch more from CNET On Cars - Cooley shares his handy tips for plugging an electrical leak in your car.
The internal resistance of a battery is defined using two techniques: direct current (DC) by measuring the voltage drop at a given current, and alternating current (AC) (AC). When evaluating a responsive device, such as a battery, the researchers switch back and forth between the DC and AC test procedures, although neither reading is correct or incorrect.

If you are testing a 6V battery a good battery will show a reading of between 4V to 6V. Anything less than 3.5V can show that the battery is dead and will need replacing. A general rule of thumb is if the level of voltage reads half or less than the specified voltage the battery is considered dead and not fit for use.

Battery management systems must not only monitor temperature and voltage but must also monitor current in its system. It must be able to ensure that excessive amounts of current are not flowing through the system. They''re required to log abuse conditions. In order to monitor electrical current through a BMS, we cannot measure current directly.
