The AGM Battery 12V 138Ah Ultracell UC-138-12 is an AGM technology battery. This means that we can forget about its maintenance.

Characteristics of the AGM Battery 12V 138Ah Ultracell UC-138-12

The Ultracell UC-138-12 12V 138Ah AGM Battery does not require maintenance, as it is a sealed monoblock battery, so it can be installed indoors with poor ventilation. It is also a battery that, because it is made of ABS, has great resistance to the most demanding external conditions and is very resistant to the sulfuric acid that it stores inside.

The AGM Battery 12V 138Ah Ultracell UC-138-12 has high quality and durability as well as excellent performance and versatility of use, it is a very competitive battery in the photovoltaic sector and with technical characteristics that are very attractive in comparison with other batteries from well-known manufacturers.

The compact size of the Ultracell UC-138-12 12V 138Ah AGM Battery makes it easy to transport and handle. Even if it is overturned, it will not spill acid, but it is recommended that it not be overturned during transport or during handling, nor of course, during operation. To optimize the useful life of the Ultracell UC-138-12 12V 138Ah AGM Battery, it is also recommended that its discharges not exceed 30%, so it is a battery that, although it does occasionally accept deep discharges that are taken as a habit it can significantly shorten its lifespan.

The AGM Battery 12V 138Ah Ultracell UC-138-12 is a 12V voltage battery, AGM technology and deep cycle. Starting at the end, deep cycle batteries are characterized by holding up better against deeper discharge cycles than generic AGM. The entire Ultracell UC range that we offer at Autosolar uses deep cycle AGM technology.

The battery is 12V, which is the usual voltage for monobloc models. Internally, like all types of batteries with these characteristics, it consists of a series of 6 cells of 2V each to provide the final 12V of voltage.

Other interesting technical characteristics of the AGM Battery 12V 138Ah Ultracell UC-138-12 can be the following:

- Dimensions of 410 x 177 x 225 (including the connection terminal) mm.

- Approximate weight of 38 kg

- Capacity in C100: 138Ah

- F11 type terminal for screw.

- Absolute limit voltage with discharged battery: 10.8V.

- VRLA battery without maintenance (Valve Regulated Lead Acid).

- AGM technology with absorbent glass separator between the lead plates.

The 12V 138Ah Ultracell UC-138-12 AGM Battery, as we can see above, is of AGM technology and, therefore, VRLA (maintenance free). This allows us to use a lead battery without the danger of gas emissions or acid spills. The electrolyte with which the chemical reaction of the battery is made is contained in fiberglass meshes between the lead plates, which makes them very safe to work in delicate environments.

The Ultracell UC-138-12 12V 138Ah AGM Battery is manufactured under the strictest controls and with the highest quality components that a manufacturer like Ultracell can offer; world's leading brand in batteries. If we have the battery connected to a small solar installation, we must bear in mind that we must use a charge regulator that is properly configured so as not to damage the battery. On the other hand, if we are going to charge it with a battery charger, we must use a charger that is suitable for the characteristics of this battery, both in terms of technology and capacity.

Common uses of the AGM Battery 12V 138Ah Ultracell UC-138-12

We can use the 12V 138Ah Ultracell UC-138-12 AGM Battery for a wide variety of uses, trying to avoid it being used to power electric motors or other traction operations.

The Ultracell UC-138-12 12V 138Ah AGM Battery is indicated for small solar installations, lighting, signaling, auxiliary battery for caravans, powering low consumption in field huts, etc. What must be taken into account is that in order to preserve the maximum useful life of the Ultracell UC-138-12 12V 138Ah AGM Battery, it should not remain discharged for long periods of time.

Useful life of the AGM Battery 12V 138Ah Ultracell UC-138-12

One of the most important factors that determine the useful life of the Ultracell UC-138-12 12V 138Ah AGM Battery is the number of deep discharges and their percentage of discharge, the behavior in the different scenarios is shown below.

Installation of the AGM Battery 12V 138Ah Ultracell UC-138-12

The 12V 138Ah Ultracell UC-138-12 AGM Battery must be installed to work in a vertical position, with the terminals at the top. Although sealed batteries do not leak liquid, they cannot work lying down, since internally it is designed to facilitate gas recombination and its internal recirculation is not correct if the battery is not installed in the proper position.

To take care of the Ultracell UC-138-12 12V 138Ah AGM Battery, extreme temperatures must be avoided, such as outdoors, both in winter and in summer. It is also important that it is in an optimal state of charge most of the time.
