Advantages of cynetic cpzs accumulator batteries 2v batteries 
 One of the advantages of 2 volt cpzs batteries is that they provide, together with opzs batteries, the longest life that can be obtained from lead acid technology. Its tubular lead plate construction is the longest built for deep cycle applications such as solar energy. The price is much lower than an opzs battery, both having the same number of cycles 1500 to 80% and 2500 to 50%, therefore the same duration in deep cycle uses. Thanks to this lower price we can buy a battery with more capacity compared to an opzs for the same price with the advantages that this implies , such as a lower depth of discharge and therefore a longer duration. 
 If we order the market options in lead acid batteries we have from longest to shortest duration (cycles): 
 Opzs and cpzs batteries> tubular monoblock batteries (cynetic tubular)> flat plate deep cycle batteries (trojan, us battery or rolls 4000 type)> standard 12v solar monoblock batteries> starter batteries (truck) 
 Differences between cpzs batteries and opzs batteries 
 One of the differences between cpzs and opzs batteries is the plastic used in the container, which in the CPZS case is flexible and opaque polypropylene compared to the transparent SAN plastic of the opzs batteries. 
 Another difference is that in the case of opzs we have a greater electrolyte reserve compared to cpzs. This means that in the cpzs we must add water every 2 or 3 months and in the opzs by having a greater reserve we can lengthen these periods twice and in the case of the cynetic opzs even eliminate maintenance. 
 These are the main differences, as we have commented in both cases, the technology inside is the same in opzs and cpzs thanks to its tubular plate with the same number of cycles (times that can be loaded and unloaded), so both options allow us They will give the best result available on the market for solar and deep cycle installations. 
 Charging and maintenance of cynetic cpzs batteries 
 The charging of the 2 volt cynetic cpzs batteries can be done using solar regulators or chargers. In solar installations we recommend charging the batteries at a voltage of 2.48v per cell in the absorption stage with between 2 and 3 hours of time in this stage. It is recommended to equalize (see what the equalization charge is) once a month at 2.60v per cell for 3 or 4 hours depending on the depth of discharge. 
 For the maintenance of cynetic cpzs batteries we only have to worry about filling with distilled water when they need it. As an automatic filling system is supplied as standard, we will be able to see the water level of each glass with the level indicator of each stopper in a comfortable way and fill when it marks low level. 
 Cynetic cpzs batteries extended warranty 
 Cynetic batteries, due to their high resistance, have a guarantee against a manufacturing defect of 3 + 2 years in which the first 3 years the guarantee is total and in the unlikely event that they had a fault in an element outside these 3 years of guarantee would apply a discount of 50% the 4th year and 40% the 5th year on the acquisition of a new one. 
 
 Manufacture of cynetic cpzs batteries 
 Cynetic cpzs batteries are manufactured in the european union with the strictest environmental and quality control regulations. All the machinery and production lines of our batteries use the German HADI system, the same as the leading brands.
