Battery terminals should be coated with grease or petroleum jelly to prevent oxygen from coming in contact with the terminal and contributing to corrosion. Brass terminals are far more desirable because they maintain a tight connection on the battery terminal. Inexpensive lead battery terminals do not work very well because they tend to loosen in time and corrode at the connection points. The type of terminals used also affects the starting power of the battery. The battery terminals should be cleaned and tightened because starting problems commonly can be traced to bad connections at the battery. If you get a voltage reading, the battery should be cleaned. You can check this with a digital volt meter by touching the positive terminal of the meter with one lead and touching the top of the battery in different places with the other. Battery acid that settles on the top of a battery will create a minor short between the positive and negative terminals and shorten the life of the battery. The battery should be kept clean by using a baking soda and water solution. Good maintenance practices can extend the life of your battery in your classic car. They are pro-rated based on the retail price of the battery and a credit is given towards a new battery based on how many months the battery was used against the length of the warranty. To avoid a battery that has begun to sulfate, be sure to select the newest battery available.īattery warranties are pretty much the same throughout the industry. So, for example, if you see a code B5, that means the battery was manufactured in February 2005. The letter (I) is not used because it can be confused with the number (1). The letter (A) is for January and the letter (M) is for December. Most batteries have a date code on them indicating when they were manufactured. In most cases the battery will not recover from this condition and will need to be replaced. In time, the plates in the battery will become so heavily coated that the battery dies. ![]() The sulfur molecules in the battery acid become so deeply discharged that they begin to coat the battery plates. The most common situation where you find sulfating is in a battery that has not been charged for an extended period of time. Batteries that sit for long periods of time without being recharged will experience sulfating of the internal plates. These do not sulfate or degrade as easily as a wet cell battery, which makes them more desirable for use in sporadic use vehicles like classic cars.Īnother thing that is very important to consider when selecting a battery is how long it has been sitting on the shelf at your local parts store. Gel cell batteries usually cost twice as much as a wet cell, but the advantage of a gel cell battery comes when storing your classic car for a period of time. The wet cell also comes in two different types: serviceable and maintenance free. Batteries come in two types, wet cell and gel cell. When purchasing a battery for your classic car, you should select one with the highest reserve capacity or the highest amp hour rating. So let’s talk about some of these common problems, their causes and the solution steps you can take. Battery and electrical problems were the second most common problem during the yearly classic car Glidden Tour that I used to work with. You can extend the life of your battery with some good common sense maintenance practices. This has a negative effect on battery life. Most classic cars are not driven 365 days a year, and in most cases, they sit in storage more than they are driven. You can expect good battery life to be anywhere from a year to 48 months, yet only about 30% of these batteries will reach the 48 month mark. For car batteries, the life span of a battery depends on how it is used. The use of lead acid batteries goes back over 100 years and the principal used to store and unlock chemical energy is basically the same as it was a century ago.
