Dear Experts,

I have a SITOP UPS1100 6EP4135-0GB00-0AY0 and was left connected to a SITOP UPS1600 module for at least 6 months. Will the battery module drain? I am only getting 12VDC from the battery terminals.

By some wild chance, is it technically viable to charge the battery without the UPS1600 connection by directly connecting 24VDC into it? (The UPS1600 is not available now as it is installed online to a system.)

Thanks in advance for your responses.

Best Regards,

Clark

No, you should not charge bettery directly with appling 24 V DC supply since its charging cycle is special. 

Please refer How can you recharge batteries faster that are connected to a SITOP UPS1600? FAQ which will guide you to procedure to charge battery.
