Increase backup time

[Anonymous user]

Hi,

I Have a APC BACK-UPS 500VA (300 Watts) I would like to know what modification required in PCB that i can get better back up time,

and minimum output Volts 170 at backup time?

Regards,

This is a very small unit so it doesn't give much runtime and doesn't offer any "official" ways to extend that runtime. Some of our unis have the ability to have external battery packs, but this unit does not. If anyone has any other ideas outside of APC, please reply.

You could get a bigger battery (not a car battery that is dangerous) like mabe 5-10ah more
