Ever tried powering a solar array with regular batteries and watched them gasp for breath after two winters? That's where GEL 12V 75AH batteries like Huizhong Power's solutions come roaring in. Unlike their liquid-filled cousins, these batteries use thixotropic gel electrolytes - imagine battery acid with the consistency of set honey - that prevent acid stratification and reduce maintenance headaches.
Take Huizhong's flagship model - the HZY12-80. This workhorse delivers 75AH capacity at 12V, but here's the kicker: its gel matrix allows 500+ deep cycles at 20% depth of discharge. Compare that to standard AGM batteries that typically tap out at 300 cycles under similar conditions. For telecom base stations using these units, we're seeing average replacement intervals stretch from 3 years to 5-7 years.
While AGM batteries might win in cold cranking amps (perfect for your diesel generator), GEL tech shines in sustained deep-cycle applications. A recent maritime case study showed Huizhong's 75AH units maintaining 12.2V after 72 hours of continuous navigation equipment load - that's 18% longer runtime than comparable AGM models.
Thinking of stacking these in your server room? Remember:
With new developments like carbon-doped gel electrolytes pushing cycle life beyond 1,200 cycles, these batteries are becoming the Swiss Army knives of energy storage. Whether you're powering an off-grid cabin or backing up a 5G tower, that 75AH capacity packed in a spill-proof, maintenance-free package is hard to beat. Just don't try using them as boat anchors - at 24.5kg each, they'll sink your dinghy faster than you can say "deep cycle"!

North Korea is a net energy exporter. Primary energy use in North Korea was 224 TWh and 9 TWh per million people in 2009. The country's primary sources of power are hydro and coal after Kim Jong Il implemented plans that saw the construction of large hydroelectric power stations across the country.
Hydropower is the dominant form of electricity generation in North Korea. The country’s numerous mountains and rivers make it an attractive choice for power generation. As noted in article one of this series, Statistics Korea estimates it accounted for 53 percent of all power generation, while Nautilus Institute put hydro at 76 percent.
This installment of our series on North Korea’s energy infrastructure will examine one of North Korea’s largest hydroelectric power installations: Huichon Power Stations No. 1 through 12. Construction of the system first started during the Kim Jong Il era and ended in the Kim Jong Un era.
Preface North Korea suffers from chronic energy shortages. Rolling blackouts are common, even in the nation’s capital, while some of the poorest citizens receive state-provided electricity only once a year.
Under North Korea’s two-tier energy system, which prioritises industrial facilities, the only way for many citizens to access electricity is to pay state functionaries to allow them to install cables to siphon off power from local factories.
Access to solar panels has created capacity where the state falls short, but the overall energy security challenges facing the nation are daunting. This report, “North Korea’s Energy Sector,” is a compilation of articles published on 38 North in 2023 that surveyed North Korea’s energy production facilities and infrastructure.
