CPZS batteries: The best quality-price ratio on the market.

    CPZS batteries: The best quality-price ratio on the market.

    In this new post we are going to talk about stationary glass batteries, specifically, the CPZS batteries. These batteries are generally little known and offer an unbeatable quality-price ratio.

    They are tubular lead plate batteries for solar applications. Their 99,9% pure lead antimony composition makes them suitable for intensive use, with continuous charge-discharge cycles and deep discharges of up to 80%. It has waterproof terminals and bridges that guarantee a useful life without sulfation.

    – They have the longest duration that can be obtained from lead acid technology.

    – Price significantly lower than the topzs and opzs batteries, having the same duration in deep cycle uses (1500 cycles at 80% discharge)

    Differences between Cpzs and Topzs batteries 

    In both cases the technology inside is the same and they have the same number of cycles. Now, how are they different? Only in the type of container and the antimony content.

    – The container on the Topzs batteries is translucent white and allows for visual water control. In the case of Cpzs it is opaque and the water control is done through the self-filling plugs with a level viewer.

    – Topzs batteries have a low antimony content. 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 extend these periods by double.

    Maintenance of Cpzs batteries

    We only have to worry about refilling distilled water when needed. We can see the water level of each glass with the level indicator on each cap in a comfortable way and refill when it shows a low level.

    C10 or C100 discharge type of stationary batteries

    Finally, know that the capacity values ​​of our batteries are expressed for a discharge time, whether C10, C100 or another. Not all manufacturers tell us the capacity of their batteries in C100 and if we make the mistake of comparing a battery with capacity expressed in C100 with another battery with capacity expressed in C10 or C0 we will not be comparing the same thing.

    Let's imagine the stationary battery “X” for which the manufacturer tells us it has:

    900 Ah in C100

    686 Ah in C10

    590 Ah in C5

    510 Ah in C3

    353 Ah in C1

    We can observe that, for the same battery, slower discharges such as C100 deliver a greater number of Ampere-hours (Ah), in this case 900 Ah, than faster discharges such as 1 hour (C1) can only offer 353 Ah. .

    We can imagine the example of a runner capable of running for 6 hours at an easy pace and covering 50 km. Or run very fast for 5 minutes and only travel 1 km. In both races the runner ends up exhausted, but in the first he covers much more distance than in the second.
