apc ups battery replacement
I need to replace the battery in my APC UPS. Model BF500.
I looked up a replacement battery on the APC site. ~$40.
I looked it up on some other sites and cross referenced it.
It seems it is just a 12 volt sealed gel deep cycle battery.
This thing is 5 years old and it has been very good to me.
It is out of warranty, so I was thinking about an upgrade.
When it was new it gave me about 5 minutes to shut down.
Now it gives me about 90 seconds. If I'm lucky.
Since it is a 12 volt battery, why can't I go get a big marine battery
like the kind used for trolling motors and hook it up in place of
the battery that is in there now. The battery could just sit
on the floor next to the unit. That should give me hours of shut down time.
So what do you think. Would it work?
