High performance, long service life and a huge weight are known for lead-acid batteries. Gleichmann supports three different types of sealed lead technologies: lead-acid, lead-fleece and lead-gel.
Lead-acid as the oldest lead technology is mainly used for high current rates within a short time. Additionally to lead and acid it contains water to cool the battery whilst warming-up because of pulling high current rates and to avoid the inflammableness.
A similar structure to lead-acid has the lead-fleece technology: lead plates are separated by fleece plates. This type offers high current rates for a short while as well but its disadvantage is that the fleece gets dry and porous that is why the cycle life can be shorter with this type.
Lead-gel batteries are for non-portable products only. The gel desiccates slowly which supports a longer life time. By too much movement of the cell the gel creates air bubbles which are bad insulators. As a consequence they course the warming-up inside the cell and make it useless for the long-term usage.
