hi


car battery has a large supply of current(more stamina)
it can give a lot of current about 10/20 A for hours

but lead acid battery has 2/3 A current only

The last writer is correct. Normal car batteries have much more power capability (high currents) than sealed lead acid batteries (also known as SLA)

What kind of batteries would experts suggest for home soler power system
of abbout 3.5 kwh ?

 

[PaulHolland]

Normal sealed CAR batteries or unless you can ventilate the site normal lead acid batteries, WHY ?. They are cheaper and better in handling power and you can get them all around the world.

Hi
The only differences between car lead acid battery and sealed lead acid battery as the name implies you don t need to add water periodically ( maintenence free) and as you will operate it in home i suggest sealed battery as you will not need ventilation. As for the current capability I don t agree with other friends about it , both batteries has a high current capability, that is why both are used on cars tha need a high starting current ( hundreds of amps in big cars you reach 400 a easily)
