VRLA Lead-acid batteries have long been popular for solar system and UPS backup system, due to the reliability if well-managed & low initial project cost. However, li-ion batteries has been capturing more interest for some time now.
How to Selection : Li-Ion vs VRLA batteries ?
1. COST : Lifepo4 batteries price would be more than 4-5 times higher than VRLA AGM Battery
2. Weight: Lead-acid battery (VRLA) is a battery whose electrodes are mainly made of lead and its oxides, and the electrolyte is a sulfuric acid solution. VRLA Battery 200% Heavy then Lion battery.
3. Depth of discharge :
Lithium battery is a kind of battery that uses lithium metal or lithium alloy as negative electrode material and uses non-aqueous electrolyte solution. Lithium batteries can be roughly divided into two categories: lithium metal batteries and lithium ion batteries.
Usually VRLA battey use at 50-80% Deepth, and Lithium battery use at 80-100%.
4. Safety: Lithium Battery is light weight, but May explode if used incorrectly! VRLA Battery is a little heavy, but its 100% stable and safe, will never cause danger to you!
5. Lead in batteries can be recycled and reused, reducing environmental pollution. Lithium batteries are not recyclable, they can only be thrown away when worn out.
Generally speaking, VRLA Batteries would be more safe, competitive than lithium batteries, and especailly for the life span of High temperature deep cycle gel battery, lead carbon batteries are almost close to lithium batteries service -working over 6 years is available for solar system ; over 15 years for UPS backup.
