Thanks for all the helpful responses.
The battery bank is composed of 8 Trojan L-16E batteries in series
with around 2.6 kW of PV on an older 48 V Outback system with one VFX
3648 and one MX-60. I did not install the system, but I did supply
the faltering bank of replacement L-16s.

Drake,
Your request is missing specifics so my answer can only be generic.
Get away from all L16s. Go to one string of industrial cells. There
are numerous well-respected brands. I would put HUPs at about the
top. <http://www.hupsolarone.com>www.hupsolarone.com. Spend some
time on this website and it will become more clear.

Hello Wrenches,
Even after my clients have learned to maintain their batteries
properly, the Trojan L-16 batteries continue to crater, one cell at
a time. One client is considering spending $12,000 on a nickel -
iron battery bank he found on the web. This seems like a
ridiculously large investment, but he is feeling desperate. We
urgently need another option from the Trojan L-16s.
How are the Surrette L-16s holding up? Would you recommend them as
worth the extra investment?
What is the best battery to use in an off grid system these days.
Thanks,
Drake
