FAQs about Valve regulated lead acid battery cycle times
How does a valve regulated lead-acid battery work?
The valve-regulated lead–acid (VRLA) battery is designed to operate by means of an internal oxygen cycle (or oxygen-recombination cycle), where oxygen is evolved during the latter stages of charging and during overcharging of the positive electrode.
What are valve-regulated lead-acid (VRLA) batteries?
Valve-regulated lead–acid (VRLA) batteries are also referred to as 'recombinant' batteries. Unlike flooded batteries, which lose water as a result of oxygen and hydrogen evolution at the positive and negative electrodes respectively during charging, in VRLAs, oxygen will recombine with the hydrogen to reform water .
Do valve-regulated lead-acid batteries have a charge profile?
Charge profiles for new 6 V 100 Ah valve-regulated lead–acid (VRLA) batteries at different charge voltages and temperatures.
