The setup I have is 2 uhf 50 watt repeaters with a 25 watt Philips repeater
on two optima batteries with regulator charged by a 200 watt wind generator
and 4 80 watt panels .However I will be seperating 1 50 watt repeater off
onto its own battery system as soon as we can get to the site to reduce the
load on the other bank .But I am finding the yellow tops don't have the
reserve that the ordinary lead acid batteries for dozers 1000ah have.
Thank You,

Ian,
The best type of battery for backup repeater power is, in my opinion, a
valve-regulated, sealed lead-acid battery using absorptive glass mat design.
In the solar-power industry, this battery is described as a VRSLA-AGM
battery.
When floated on the appropriate solar, wind, or utility power supply with
the appropriate charge controller, such batteries can provide reliable
backup power. I use the term appropriate for good reason; most of the
battery systems that have failed in my area did so because inappropriate
batteries (automotive wet cell) were used, or because the float voltage was
incorrect or poorly regulated. My 35 watt solar-powered mountaintop UHF
repeater has been in service for 4.5 years with 100% availability, using two
75 watt solar panels, a SunWize SIGMA charge controller, and two 105 AH
Concorde VRSLA-AGM batteries. Very simple and very reliable.

Hi guys. Can anyone suggest the best type of batteries for repeater sites?
It seems our ordinary lead acid batteries are surviving better than optima
yellow tops over 2-3 days of rainy weather. Would anyone have any other
sugestions?
Thank You,
