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. Reproduced from Culpin B (2004) Thermal runaway in valve-regulated lead-acid cells and the effect of separator structure. Journal of Power Sources 133: 79–86; Figure 1. Figure 9.
How long does a lead-acid battery last?
general rule of thumb for a vented lead-acid battery is that the battery life is halved for every 15°F (8.3°C) above 77°F (25°C). Thus, a battery rated for 5 years of operation under ideal conditions at 77°F (25°C) might only last 2.5 years at 95°F (35°C).
When should a lead-acid battery be recharged?
To ensure maximum life, a lead–acid battery should be fully recharged as soon after a discharge cycle as possible to prevent sulfation, and kept at a full charge level by a float source when stored or idle (or stored dry new from the factory, an uncommon practice today).
When were lead-acid batteries used in e-bikes?
Lead-acid batteries were used in e-bikes for the first time in the early 1900s [103–105]. The first generation of lead-acid batteries had a liquid acid electrolyte, which required more maintenance, and involved chemical leak hazards when the battery or bicycle fell .
