LITHIUM BATTERIES<\/strong><\/p>\n Lithium batteries are the best so far on the market because of their light weight, longer life span and a high depth of discharge. The lifespan of lithium batteries ranges from 10 years and above depending on manufacturer, as for the depth of discharge they range from 80% to 90% depending on the manufacturer. For instance, the depth of discharge of Pylontech lithium batteries is at 90% even though they recommend the batteries to operate below 90%. The operating temperature of lithium batteries ranges from 0 degrees to 40 degrees. Charging or storing in a high temperature environment may permanently damage the battery capacity and further accelerate battery life degradation, resulting in a rapid reduction in standby time. When using the device at low temperatures, you may find that the battery life is shortened. This is the characteristic of all lithium-ion batteries at low temperatures, but this phenomenon is temporary, when the battery temperature returns to the normal range, performance will also return to normal. Lithium batteries normally come with a battery monitoring system(BMS) which provides the battery with protection against short circuit, overcurrent, over temperature, over discharge and overcharging. Most of the lithium batteries like the pylontech battery enters a sleep mode to avoid overdischarging. Also in some lithium batteries there is a centralized unit in BMS, that enables functions such as remote measurement, remote communication and remote controlling to be available. Lithium batteries are more than 95% efficient.<\/p>\n The graph below is showing how lithium batteries discharge.<\/strong><\/p>\n The graph below is showing the charging of lithium batteries relative to lead acid batteries<\/strong>.<\/p>\n Advantages<\/strong> Disadvantages<\/strong> 2. GEL BATTERIES<\/strong><\/p>\n A gel battery, also known as a \u201cGel Cell\u201d, is a VRLA (valve-regulated lead\u2013acid) battery, a type of Sealed Acid Battery. The technology used in making gel cells is similar to AGM batteries. However, instead of utilizing the Absorbent Glass Material that AGM batteries use, gel batteries make use of gelled electrolytes. The solidified electrolytes reduce the risk of spillage and evaporation that results in corrosion problems. This technology uses a small amount of solidified electrolyte to keep the acid immobile. Gel batteries have longer lifespan than traditional batteries, this is due to the fact that the gelled solution can hold their charge for a longer time. This battery type is also durable and can withstand extreme ranges in temperature. The Gel batteries like the lead acid batteries they have a depth of discharge of 50% which is lower than that of lithium.<\/p>\n Advantages<\/strong> Disadvantages<\/strong> 3. LEAD ACID BATTERIES<\/strong><\/p>\n Lead acid batteries uses sponge lead and lead peroxide for the conversion of the chemical energy into electrical power. The graph below is showing how a lead acid battery charges<\/strong>.<\/p>\n Advantages<\/strong> 4. SALTWATER BATTERIES<\/strong> Advantages<\/strong> \u2022 They have a long lifespan; saltwater batteries have long lifecycles, which means they can be used for longer periods of time than many other battery options on the market. This has many implications \u2013 for example, you likely wouldn\u2019t have to replace a saltwater battery as often as you would with most lithium-ion batteries, which can save you money in the long run.<\/p>\n \u2022 They are easily recyclable, because they lack availability of heavy metals and toxic materials.<\/p>\n Disadvantages<\/strong> <\/p>\n Compiled by:<\/strong><\/p>\n Naison Charapuse<\/strong><\/p>\n","protected":false},"excerpt":{"rendered":" \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 Solar Batteries brands Terms used […]<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[1],"tags":[],"class_list":["post-1363","post","type-post","status-publish","format-standard","hentry","category-uncategorized"],"featured_image_src":{"landsacpe":false,"list":false,"medium":false,"full":false},"_links":{"self":[{"href":"https:\/\/www.nettzenergy.com\/index.php?rest_route=\/wp\/v2\/posts\/1363"}],"collection":[{"href":"https:\/\/www.nettzenergy.com\/index.php?rest_route=\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.nettzenergy.com\/index.php?rest_route=\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.nettzenergy.com\/index.php?rest_route=\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.nettzenergy.com\/index.php?rest_route=%2Fwp%2Fv2%2Fcomments&post=1363"}],"version-history":[{"count":6,"href":"https:\/\/www.nettzenergy.com\/index.php?rest_route=\/wp\/v2\/posts\/1363\/revisions"}],"predecessor-version":[{"id":1377,"href":"https:\/\/www.nettzenergy.com\/index.php?rest_route=\/wp\/v2\/posts\/1363\/revisions\/1377"}],"wp:attachment":[{"href":"https:\/\/www.nettzenergy.com\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=1363"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.nettzenergy.com\/index.php?rest_route=%2Fwp%2Fv2%2Fcategories&post=1363"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.nettzenergy.com\/index.php?rest_route=%2Fwp%2Fv2%2Ftags&post=1363"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
