[RE-wrenches] Concorde AGMs

[Mark Dickson]

This issue was with one of their large 4V flooded batteries.  Our customers
accidentally tried to lift the battery by its cover edges and it popped
off--luckily, it was a dry back-up battery!  Surrette told us not to worry
and to pop it back on and seal around the terminals and the bottom of the
cover with the RTV.

 

So no not an AGM, but I figure it is the same basic electrolyte
chemistry-no?

Hi Mark,

 

Were you referring to the Concorde or have you seen this issue with the
Surrette AGM? Surrette AGM's look to be made by Fullriver which we sell so
I'd like to know your experience or any issues with them.

 

Thanks,
Larry

Hey Maverick,

 

I have seen this several times in Lifeline and Sun Xtender, both made by
Concorde, especially when installed on their side. It appears that terminal
corrosion starts just under the case covering the terminal connection inside
the battery. Not much you can do. 

 

The attached picture shows an example of the case splitting open on a
GPL-8DL due to this type of failure.  The battery is 9 years old and still
has 70% capacity.
