Product information

The Rolls Surrette  6-CS-17PS is a 6 volt deep cycle battery rated at 770 Ah @ 100 hours rate. It differs from the 4-CS-17PS only in the number of cells, and therefore, the voltage of the battery. This is a very high capacity battery with new generation series 5000 advantages and features like: dual case, replaceable cells, small foot print and an expected life of 10 years.

The high capacity, deep cycle Industrial Flooded batteries from Rolls Surrette feature a heavy duty plate grid, double insulated with a polyethylene envelope and a glass mat to protect against positive plate breakdown, as well as prevent treeing, cracked or misaligned separators, or shorting at the bottoms or sides of the battery.

The 2VDC cells are each built into their own lightweight, polypropylene container with a thermally bonded cover to prevent acid leakage, then placed within an outer container of durable polyethylene with a removable lid, ensuring that the battery is operable and unspilled, even if the outer case is damaged.

Both the CS and KS series of the Surrette Rolls batteries allow for disassembly, where each cell can be removed independently. This makes it possible for each cell to be replaced without special tools, and creates ease for on site installation.

These Rolls Surrette batteries are rated at 3200 cycles at 50% of discharge, and are backed by a seven-year limited warranty. Surrette Rolls batteries of Series 4000 come with a complete replacement warranty within the first 24 months from the date placed in service. After the first 24 months of service the warranty will be adjusted for a period of up to 84 months from the date first in service.

Shipping information

All Surrette Rolls batteries ship via LTL freight, therefore the store's free shipping does not apply. We cannot ship batteries via carriers like UPS and Fedex.

There are a few things to keep in mind when shipping batteries: batteries shipped individually have a higher risk of being damaged during transit, and shipping 1 or 2 batteries is usually not cost-effective. We advise to have at least 3 or 4 batteries in your order shipping together.

We do not store batteries in our Emeryville office; our closest distribution center for pick-ups is in South San Francisco. A distribution center in Sacramento is also available.

Any damage should be noted upon delivery. It is extremely challenging to successfully claim any damage after the fact. Always carefully inspect all merchandise upon delivery; if you notice any damage please ask the driver about the correct protocol and always note it in the BOL or delivery receipt.

Battery maintenance

How To Care for Your Batteries

Batteries vary by chemistry and configuration, which means that the required maintenance also changes. Some of these maintenance tasks may be automated or performed remotely via charge controllers or battery management systems, including charge regulation, voltage checks, and related measurements. Others require on-site manual operations or oversight. These tasks include, but are not limited to, adding water or equalization.

Sealed lead-acid batteries, gel cells, and absorbed glass mat (AGM) batteries are often called maintenance-free, because they don’t require manual maintenance like watering or an equalization charge. While this makes them suitable for remote or unattended power systems, sealed batteries need accurate regulation to keep them from overcharging or over-discharging.

Lead-acid Batteries

Lead-acid batteries should be recharged as soon as possible, with no exceptions. This is because the positive plates change from lead oxide to lead sulfate as it discharges. Should the plates be allowed to stay in a lead sulfate state instead of immediately charged, the plates will remain partially sulfate even when fully charged.

Parts of the plates that are sulfate cannot hold energy any longer, which reduces the effectiveness of the batteries and their lifetime. For example, batteries that are only partially charged on a regular basis tend to fail in less than a year. While new lead-carbon batteries dramatically reduce sulfation, they still need to be recharged immediately to keep them in good working shape.

Remember, battery warranties never cover damage due to poor maintenance or loss of capacity due to sulfation, so proper maintenance is key.

Wet-cell or Flooded Batteries

Wet-cell or flooded batteries need their electrolyte levels checked at least once every three months. At the same time, the batteries will need to be topped-off with distilled water.

However, water should not be added to fully discharged batteries. As these batteries discharge, they absorb electrolytes. If water is added while the battery is discharged, then the battery is recharged, the electrolytes will overflow and create a safety hazard.

The tops of the batteries should be kept clean and cables should be tight. If the cables are loose, do not attempt to tighten or remove them while charging or immediately after charging. Any spark around the batteries has the potential to cause a hydrogen explosion inside the case, igniting a fire or causing a larger explosion.

Should the batteries show a variation of 0.05 or more in specific gravity from one another, they will need an equalization charge. This is essentially a steady overcharge that brings the batteries to a bubbling state.

With proper care as outlined above your batteries should remain in good working condition throughout their service life and serve well as part of any power system.

How To Measure Battery State-of-Charge

Essentially, battery state-of-charge (SOC) can be easily measured using an amp-hour meter, by voltage, or by specific gravity. Measuring SOC by voltage or specific gravity requires specialized knowledge and a great deal of care, so it is recommended that owners utilize amp-hour meters for all battery systems.

An amp-hour meter is somewhat like a fuel gauge for batteries, providing all the information necessary to keep the batteries charged. While using an amp-hour meter, users can see the system’s voltage, current, and battery condition.

The voltage of a particular state-of-charge will vary depending on which state the battery is in; charging or discharging. Also affecting the variation is the current in relation to the size of the battery. It is important to remember that voltage will vary with temperature.

While the battery is charging, a lower outdoor temperature will increase battery voltage. For example. the full-charge voltage on a 12 VDC battery is 0.9 VDC higher at the lower temperature of 32℉ than at 70℉. The opposite is true for discharging. While discharging, a higher outdoor temperature results in higher voltage.

While a battery is idle, the temperature has little effect, although very high temperatures may increase the self-discharge rate.

A hydrometer may also be used to measure battery state-of-charge in flooded lead-acid batteries by measuring the amount of electrolytes near the plates. However, the electrolytes can only be measured at the very top of the battery, which may or may not be near the plates.

To get an accurate reading from the hydrometer, take the readings after the battery has been idle for a long while, or after several hours of the battery slowly discharging. Near the end of the charging cycle,  gas bubbles rise through the sulfuric acid. It takes a few hours to mix enough to get an accurate reading with the hydrometer.

Whether a hydrometer or an amp-hour meter is used to measure battery state-of-charge, using them will allow you to determine where your batteries are in the stages of charging or discharging.

How to select the right battery

Selecting the right battery for your application

The first and most important step to configure your battery back is to know your system's voltage. Small systems used in RVs and boats are usually 12V. It is recommended to use 24V or 48V for medium sized energy systems and always 48V for large systems. Some systems can even go up to 60V, however, 12V, 24V and 48V are the standard in solar and renewable energy systems. Whatever your system voltage is, keep that number in mind since it will be consistent across your system design; changing your system voltage down the road could be a costly alternative.

Another factor is to know the space available for the batteries, this is especially true for mobile applications and systems with a designated battery enclosures. These type of enclosures are usually designed for a certain type and number of batteries, for example, four L-16 batteries.

Knowing the type of battery you want is also part of the selection process. You only want to use deep-cycle batteries in renewable energy systems. Lead acid batteries are the most common, they can be flooded or sealed. Flooded batteries require periodic maintenance such as refilling water levels while sealed or VRLA batteries are considered maintenance free. Flooded batteries are seen in most renewable energy systems mainly because of their lower cost. Applications in remote locations with difficult access call for sealed batteries that do not require constant human supervision. Both batteries, flooded and sealed, are comparable in terms of performance; the determining factors are the application and cost.

A factor that requires careful consideration is your energy needs which ultimately will determine the size of your battery bank. Technically speaking, the larger the battery bank, the better. A large battery bank will reduce the depth of discharge of each cycle, thus extending the life of the batteries. Realistically, not everybody has the budget for an oversized battery bank.

Once the above factors have been figured out, the rest is relatively easy. The number of batteries in the bank will be determined by the voltage, if you have a 48V system you will need eight 6V batteries or twelve 4V batteries.

Your energy requirements will determine the capacity, or the total amount of energy stored in the battery bank. It is usually measured in charge / discharge cycles. This part can get highly technical so we are going to simplify it for the purpose of this article. The capacity of your storage is measured in Ampere-Hour or Ah per cycle. To extend the life of the batteries it is recommended to discharge your batteries less than fifty percent per cycle (50% depth of discharge or DOD). So if you know that you need 350Ah to power all your loads on daily basis, you should consider a 700Ah battery bank for a healthy life cycle. In the same scenario, a 900-1000Ah battery bank won’t hurt, it will provide additional energy on the days when it is needed and will also help extend the life of the batteries by reducing the depth of discharge of each cycle. Needless to say it will also cost more money.

Note: As a rule of thumb, the larger the size of the battery bank, the lower the nominal voltage of each battery. For example, 12V batteries are only recommended in small systems with one or two batteries. 6V batteries are ideal for medium size banks and are widely used in renewable energy systems. 4V and 2V are high capacity batteries reserved for large energy systems.
