The state of charge of a lead acid battery is most accurately determined by measuring the specific gravity of the electrolyte. Battery voltage also indicates the level of charge when measured in an open circuit condition. For an accurate voltage reading, the battery should also be allowed to rest for a period of one hour minimum in order to let the voltage stabilize. AGM and Gel batteries can be operated vertically or horizontally. Can I reduce my maintenance by not gassing my flooded batteries?

You will reduce the frequency of watering, but will cause a condition known as stratification where the specific gravity of the electrolyte is light at the top of the battery and heavy at the bottom.

A2 = January 2012, B2 = February 2012 and C2 = March 2012 etc. VRLA batteries will self-discharge less than 3% per month at 77º F (25º C).

Flooded batteries will self-discharge up to 15% per month at 77º F (25º C).

VRLA batteries should not be stored for more than 6 months at 77º F (25º C) without recharged.

They lose water because of the gassing that they go through with every charge.

Gassing is an important part of the recharge process.

The gassing allows the electrolyte to mix well and helps the battery get back to a fully charged state at the end of the charge process.

Looking for additional information, contact Tech Support. Allow each battery in the system to stand on open-circuit for about one hour. If the battery voltage spread exceeds .15 volts for a 6-volt battery, or .22 volts for a 12-volt battery a problem is indicated. When the voltage spread indicates a problem, confirmation is accomplished by taking electrolyte specific gravity readings using a hydrometer.

If the specific gravity readings show a spread greater than .030 (30 points), give the batteries an equalization charge and re-test. How can a flooded battery’s state of charge be accurately measured? For flooded batteries, 22 degrees from vertical is the maximum recommended tilt.


  1. Dating your Vendo Coke Machine 1950 Vendo began adding a stamped three digit date code, just before the serial number. In this example, 003 is the stamped Date Code. Here is how it breaks down. 0 – Year of manufacture A single number representing the last digit of the model year. Our example shows 0, meaning.

  2. Use 1 cup of baking soda for every gallon of water. 6. What is the. To determine the date of manufacture, refer to the date code on the negative terminal which consists of a letter and a number. The letter refers to the. Shipping Date. This code indicates the month and year when the battery was shipped out of our factory.
