not charging battery of UPS

[jetjom]

good day po mga bosing. patulong naman po. yung UPS ko ayaw magcharge ng battery. natry ko na isolate yung battery then chinarge ko sa ibang charger, nagcha-charge naman. den sinukat ko yung charging voltage ng ups 7volts lang. eh di ba dpat around 20volts ang voltage nun? tama po ba? by the way, panther po ang brand nung UPS. Hope to hear from you good people. thanks po

kung more than 1 year na yung ups mo, papalitin na yung baterry nyan...

good day tony. actually sa boss ko yung UPS na nirerepair ko. 1 month pa lang yung UPS. ok naman yung transformer nya eh. tsaka yung battery ok din kasi natry ko nga charge sa ibang charger eh nag-charge naman. thanks for the reply

^ baka may shorted winding na 'yung chrager side ng transformer sir. ok ba sir kung sa iba i-charge 'yung battery (output voltage kapag naka-backup)?

[jetjom]

hello rd, which side b yung charging nung transformer, yung galing ba sa inverter or yung secondary? yap ok yung battery pagtsina-charge ko sa ibang charger.

kung 1 month pa lang yan, better pa rma mo para wala kang sakit ng ulo.....trying to repair that may mean voiding warranty, sayang, entitled pa naman yan kung purchased brand new...

thanks for the advise tony.

Agree...my mga warranty pa yan, solve na problem u...
Kya lng bka nacira na ung warranty seald nyan ndi na yan tanggapin...
Pag nyari un....Ganito gawin u.
1. Check ung wire na nka kbit sa battery, check for the voltage reading, normally kung ilan volts ang rating ng battery same lng halos ng output ng charger. ex.. kung 12V battery u dapat 12V lng din output nya

2. Kung mabba sa rating ng battery output nya, my problem na yan sa secondary side ng transformer u, most likely sa filter capacitor,diode, regulator & etc..

3. Kung ndi u shado kabisado wag u na try palitan mga said parts hehehe.. bka lalo macira...

thanks mr jones. nagawa ko na yung problema, open yung isang diode sa positive side nung voltage regulator. kaya pala kalahati lang yung voltage supply ng transformer. thanks din kay tony and rdpzycho. ang laking tulong talaga ng site na to. More power and God bless us all.
