Question about UPS Battery Backup Systems

Microtek Inverter not fully charging the batteries

I have a 6 months old Microtek 3KVA Inverter which is connected in series to 4 Brand New Exide IN 1500 Plus 150Ah rating Inverter Batteries (48 Volts system). Though the inverter charging LED indicates that the batteries are fully charged (battery charging indicator light stops flickering) none of the indicators in the four batteries show the typical green glow in the visual charge indicator. Upon connecting an ammeter in series to check for the charge current the ammeter registered only 2-3 amps initially and later dropped down to 0 Amps. What I understand from this test is that the Inverter circuitry has sensed that the battery does not require any further charging and therfore the charging amperes is zero. If this is an indication to show that the batteries are fully charged, why have the glow indicators in the battery failed to indicate green, typical color of a fully charged Exide IN 1500Plus inverter Battery.

Exide Electonics One-Ups 250VA. I am turning on this unit after a long time and the green light on the front started blinking and after a few minutes it is still blinking. Does this mean it is recharging...


The OneUPS is a really old model that has been discontinued. I'm not sure if you've recently replaced the batteries or not. Assuming that you haven't, it's likely that the batteries are dead. Given the age of the unit, I suggest that you consider getting a new UPS.

Can a car battery be refilled


you need a battery charger,density measuring tool and a lot of patience.Ina functioning new battery electrolyte measurement should read 1250.The acid part of a non functioning battery gradually is absorbed by plates and produces leadsulphur.If elecrolyte level in the battery is ok,put your battery under A High Voltage Low current charge.Use a 40Wcondensant light bulb connect a 1ampere diode in seies with it connect the +ve terminal of diode to +ve side of bettery and connect -veside of battery and 40W lamp into your mains inlet(220V or 110V).Leave your battery under charge for 24 hours .If the light bulb starts emitting light leave battey under charge for a few more days and then continue charging with a high curent(2-5)ampers-low voltage charger for a few more days.Hope your battery is back to life.N.B.IN THE FIRST STAGES OF CHARGE LIVE AND DANGEROUS VOLAGE (220) IS PRESENT AT YOUR BATTERY TERMINALS .SO BE VERY CAREFUL.

Unit came to me brand new... The Power will not come on or power up? Checked the outlet..it is hot?


Check the batteries. If they are not fully charged, it will not come on. These systems use 2 6v batteries in series to make 12v.

How to recognise original exide chloride safepower 7 ah battery


1) it'll provide 1yr guarantee..(though some retailers give 6months warranty)..
2) has a 3d hologram sticker stuck on it..
3) the month and year of manufacturing is printed..
4) has a 'safe-chloride' tag tied..
5) the anode n cathode are protected with a cap
6) (sometimes/rarely) it comes in packet or box..

best is to ask a vendor/company stockist/showroom directly....
