For over a century, lead-acid batteries have been the workhorse of energy storage technology. Although there are ‘better’ batteries out there, lead-acids are still very common due to their reliability, low cost, and robustness. This article discusses the ins and outs of lead-acid batteries, where an
These factors may lead to the situation that a lead acid battery’s charge time is maybe the most crucial of all battery-related maintenance procedures. Correct charging stretches the life of a battery and further guarantees its efficiency. This paper discusses the fundamentals of charging lead-acid
Now lead-acid batteries are the oldest modern energy storage technology existing for over 100 years. Compared to the nickel-cadmium and lithium-ion systems, old-timers still prove much reliable, cost-effective, and devise leeway in a mammoth way. This paper discusses the basics of lead-acid batterie

The valve-regulated lead acid batteries from Fengri, available as 2V single cell as well as 6V and 12V block batteries, are characterised by the innovative and patented AGM-ESS technology. The addition of gel to the electrolyte combines the advantages of the AGM battery with those of the GEL battery. This technology eliminates the need for regular topping up with water and avoids contamination by electrolyte aerosols, so minimising the required maintenance effort – and hence cost.
