[RE-wrenches] Trojan L-16s

[Drake]

Hi Tom,

These are Trojan L-16E batteries, 370 AH.  They 
have a 2 hour absorb cycle at around 29.3 
V.  There is one series string of 4 batteries in 
a small, off grid cabin that is used  3 or 4 days 
a week.  The system has 980 Watts of PV with an 
Outback FM 60 CC and an Outback 3524 VFX inverter.

I was concerned to read that John and Bob have 
been seeing more problems with the Trojan L-16s 
lately. They have been a standby for this type of 
system. If they truly are not lasting as long as 
previously, what other options do we have for a 
reasonably priced, decent quality battery in that amp hour range?

Thanks,

Drake
