Lead Acid or Dry Battery, Which is Better for UPS?

Lead acid battery= lesser price with maintenance

Dry battery= more price without maintenance

other factors are left to battery manufacturer...

Dry batteries have a much higher power density...
not a lot of people realise that.

It may also depend on what your local standards say, as flooded lead acid batteries have all sorts of additional safety and maintenance concerns that sealed lead acid batteries don't have.

If it were me I would go with AGM (Absorbed Glass Mat) sealed lead acid, especially for an emergency lighting system where you need it to work. It is sort of the standard down here for building emergency lighting systems.

hi all

i am planning since some time to build up a green energy power source, i was checking the prices recently for the Wind turbine, the vertica axis wind turbine, the soalr cells, even i was looking for infinia power dishes,

my question is i am willing to use the battery in continuous Charge to discharge up to 30% mode what is the best type of batteries can help me & what is the lifetime for such batteries

thx to all

ammar yousif

A bit pointless asking about dry cells then, as they can't be charged
Unless there is confusion over the useage of the term 'dry cells'

AGM sealed lead acid batterys are likely the most suitable and cost-effective solution.

Battery life depends on a number of factors, mostly heat, the quality of the battery float charger and the number of discharge cycles. As long as you use a decent battery charger designed for sealed lead acid batteries and keep the batteries cool you can expect, say 3-4 years of life in an application such as yours using AGM batterys.

Yes ! dry cell battery maintenance free in now a days
