Depending on the type, this battery is low-maintenance or maintenance-free.
Low maintenance version - TV types
Low-maintenance batteries can be recognised by the removable sealing plugs on the top, the vent hose and the white or transparent housing. In …
To ensure proper battery function, it makes sense to keep the battery surface clean and dry. Greasy or silicone-containing dirt on the lid can hinder the flow of current. Moisture on the battery can cause a short circuit in the worst case.
Supply batteries with grid plates
Wet (flooded) deep-cycle lead-acid batteries with grid plates are particularly suitable for small and medium-sized solar applications and wind turbines thanks to their good capacity absorption and maximum capacity reserves. Grid plate technology is robust …
Why should you charge wet batteries open?
Gases are produced during charging. As they rise, they mix the battery acid.
It is better for the battery if it is open during this process.
Important: This only applies to initial charging and to all batteries that can be opened. Never open a battery by force!
Supply batteries with armoured plates
Wet deep-cycle batteries in armoured plate or tubular plate technology are designed for the most severe loads. Due to their structure, the tubular plates used provide a larger surface area compared to grid plates and thus more active mass for the chemical …
What types of supply batteries are there?
In order to withstand the stress of cyclic operation for a long time without an excessive drop in performance, the active material in supply batteries is particularly well protected.
Depending on the technology used, this is done in different ways:
In …
Ideally, batteries should be kept dry. Even slight moisture can promote leakage currents.
If you've noticed condensation on your battery frequently in the past, such as with temperature fluctuations, or water can get to your battery, it's worth considering …
The capacity and performance of lithium iron phosphate batteries are very high compared to other batteries of the same box size. They have an extremely long life expectancy, low self-discharge and can tolerate the highest charging currents. To fully charge …
What does absolutely maintenance-free mean?
Absolutely maintenance-free batteries are valve-regulated lead-acid batteries or VRLA batteries (VRLA = Valve Regulated Lead-Acid) that are sealed at the factory. Here, significantly less gas is produced than in wet batteries. The gas produced remains …
The difference between low maintenance, maintenance free and absolutely maintenance free.
Low-maintenance, flooded lead-acid batteries lose fluid during normal use. They must be maintained, i.e. the fluid level should be checked regularly and the fluid loss compensated with distilled water if necessary. These batteries usually have vent caps …
