<p class="MsoNormal"><span style="font-family:"Arial","sans-serif";color:black">I calculate 4.6 hours absorb time given the solar you have here. So the charge rate at 29.3 is OK you could bump it to 29.6. It looks like decreased capacity because of improper
charge parameters. You have to bring batteries to full charge at least once every 10 days and the only way to achieve full charge is by holding in the absorb mode through the proper time 4.6 hours.<o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-family:"Arial","sans-serif";color:black">With that said when looking here at this the bulk time (based on where the batteries were left off the previous night) bulk it typically at least one or two hours. If you add this
to the 4.6 it’s 5.6 or 6.6 hours total charge time… this will work in New Mexico or Arizona most of the year but if this is in Ohio let’s say, the real problem is not enough solar!<o:p></o:p></span></p>

<p class="MsoNormal">Hi Tom,<br>
<br>
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.<br>
<br>
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? <br>
<br>
Thanks,<br>
<br>

Hi Drake<br>
<br>
The first thing I would look at is how the batteries are being charged… Can they even be charged by the present equipment? What is the Bulk/Absorb voltage and time? Equally important is the design of the bank… series or series/parallel and if parallel how many
strings. Lastly which Trojan L-16 are these? <br>

<br>
Hello Wrenches,<br>
<br>
A 1 1/2 year old bank of Trojan L-16s had a battery with a dead cell. I have heard that there have been some complaints about the L-16s lately. Has anyone had experiences with Trojan L-16s (or the RE series), good or bad? Are they still a good choice to use
in off grid systems?<br>
<br>
Thanks,<br>
<br>
