Your terms 'standard' and 'extended' concern ampere-hour
capacity, having nothing to do with long-term reliability.
Obviously you live a sheltered life. The ***ONLY*** so-called
factory-authorized installation/service outift (for this
region) available supplied a turnkey system, supposedly
COMPLETLEY 'approved' by Best and as the 'best' cells
available. BEST supplied the battery cabinets. We learned
(later, unfortunately) there are many, many battery sets sold
for UPS applications, with widely-varying long-term quality.

First of all, regardless of current practice, as far as any
so-called battery 'switch' was concerned, an integral (and cheap)
forklift battery connector was the only means of DC isolation,
and certatinly NOT to be operated under load. That does NOT in
any way qualify as a 'switch'. Would *you* part these connectors
under load or during charging? Maybe you would.
The slimball installation/service outfit supplied 'bypass' switches
that were underrated for the apllication. The trailer-house grade
devices furnished weren't even rated for disconnect (or transfer)
under load. Sorta defeats the purpose, don't you think?

I'm talking about chicken-shit solid-state relays that had *4* wires
connected to them. *That* was a component {to them} in a battery
charger assembly. They could not determine that that "component"
had failed. We 'bought' a charger asssembly.

Who do you think you're dealing with? *Mechanical* noise.
Grounding was reworked out of neccesity immediately after
the 'blue-ribbon' crew left. It would have killed someone
otherwise.

Pre-pubic. Infantile, even. Does someone change your
diapers regularly?
Hey thunder boy:
Your cute little smart-ass comments may reveal two things.
You seem to have way too much time on your hands, and
it's very likely your uncle owns Best. I'll bet he
gave you your little pissant job, too.
Best has screwed my business associates once. Never again
if I can help it, including 'their finest', installed at no
cost. Case closed. End of discussion.
