[RE-wrenches] Fw: Trojan L-16s

Wed Aug 7 14:04:56 PDT 2013

Hi Allen,
Now that you have me thinking.....if you look at the charge recommendation 
for T-105 and L16, according to Trojan,
 they are giving us a range of 2.35-2.45V per cell @77degF.
If there is no variable other than temperature, why the range?

Re: [RE-wrenches] Trojan L-16s

Hi Allen,
I am going by experience, not only with my own (4) Workaholic L16s, but 
when dealing with customers in the field.
 I would like to get some feedback from other wrenches on this.
 Maybe it is coincidence, but there seems to be a correlation. Maybe the 
taller batteries 
experience sulfation easier?

Rgds,

Eric,
I kept this in my inbox for awhile, and finally had to ask - where did you 
get this information? I have never heard this recommendation - to charge a 
taller flooded lead acid battery to a higher voltage just because it's 
taller. I guess I see the apparent logic - more gassing addresses a 
potential for more stratification of the electrolyte - but if true, why 
have I never seen this in any battery service guide? What's your source? 
And has anyone else heard of this?
Thanks, Allan

Hi Drake, 
The L16 is quite popular in RE apps...but they typically require a bit 
higher charge voltage to reach the correct SOC than their shorter 
counterparts (i.e. T105 golf cart), 
because they are a taller battery (stands to reason .....specific 
"gravity"). Make sure they are in a vented enclosure if off-gassing will 
be an issue.
