U.S. Deep-Cycle Batteries

A short history about U.S. batteries

Deep-cycle batteries, particularly those manufactured in the U.S., require regular maintenance to ensure optimal performance. Contrary to the belief of some, these batteries cannot simply be left to their own devices. Regular care procedures, especially for battery banks, are crucial to their longevity and efficiency.

Solar storage, a rapidly growing trend, heavily relies on the health of these batteries. A single faulty battery can potentially damage the others in the bank, emphasising the importance of regular checks. Routine hydrometer and voltage testing can identify a problematic battery early, preventing damage to the rest of the bank

The history of batteries in the United States

dates back to the late 18th century, when the first electrical batteries were developed. These early batteries were used primarily for scientific experimentation and were not widely available to the general public.

In the 19th century, the development of more practical batteries, such as the Daniell cell and the Grove cell, led to the widespread use of U.S. batteries in a variety of applications, including telegraphy and electric lighting.

In the 20th century, the development of portable batteries, such as the dry cell, revolutionised the way that people used and relied on batteries. These portable batteries were used in a variety of devices, including radios, golf carts, mobility vehicles, flashlights, and portable power tools.

Today, batteries are used in a wide range of applications.

from portable electronic devices to electric vehicles and renewable energy storage systems. The development of advanced battery technologies, such as lithium-ion batteries, has further expanded the use of batteries in a variety of applications.

As with any new battery that you purchase, your U.S. battery should be given a full charge before it is used. Because these are true deep-cycle batteries, they need to be cycled a few times (6 or 7 times) before they reach their full capacity

Therefore, before fitting your new U.S. deep-cycle batteries, always check out the connection cables for wear and tear. Thus, replace them if they are found to be damaged or broken. Accordingly, it is a good thing to make sure that the battery vent caps are correctly and tightly screwed in. After fitting your battery, make sure that you keep it clean and free from white corrosion. Of course, that builds up with time.

Most batteries are now sealed. But if you have the screw-top type, then check the electrolyte level after charging. Click here to see the proper fill level. If topping up is needed, then use distilled water only. Water from the tap contains some dissolved solids and should be avoided.

Your U.S. deep-cycle batteries are at the top of the range. But it should not be discharged for more than 80% of its rated capacity. Of course, these U.S. Deep-Cycle Batteries are most suitable for boats and marine vessels, motorhomes, solar storage, and many more. So, in situations where multiple batteries are connected in series, parallel, or series/parallel, the replacement battery(s) should be of the same size, age and usage level as the companion batteries. Do not put a new battery in a pack that has 50 or more cycles. Either replace it all new or use a good, used battery.

Although many of our customers think that they can just leave the battery and it will look after itself, So nothing can be further from the truth? It is important that a care procedure be carried out. This is especially relevant to battery banks.

 Solar storage is now becoming very popular. Therefore, if you have a bad battery, it could harm the others in the bank. Hydrometer and voltage testing should be the norm. This will pick out a bad battery and save the rest from being damaged. More care and attention should be given as your batteries age. Hence, they will require longer charging times and more regular topping up.

Always use a matching charger and battery pack system. Unmatched chargers will cause potential problems. Also, extreme temperatures should be avoided. Cold reduces the battery’s capacity. One of the main dangers that can affect your battery is inactivity. If you have to store the U.S. deep-cycle batteries for an extended period without use, then buy a smart charger. This will keep your U.S. deep-cycle batteries charged to the right level before they are used again.
