My kin-1200 ap doesn't charge the battery properly.
Im using the exra battery of two 40 amp 12 volt battery.Before when i bought the ups it use to give 6 hour for 2 computers but now it only give 15 min back up for one computer.I also changed the battery but it doesn't work properly.

Re: my kin-1200 ap doesn't charge the battery properly.
The reason for this is that the UPS, is unable to efficiently charge those BIG batteries, you see they generally only charge at a low rate, anyway, of say 10% - 15% capacity, of the-battery-usually-charged. Now with these BIG 40 Amperes by 2, well, there simply isn't enough "Juice" to charge them up... (Oh it might do in a month or so)... from that UPS's Charging Circuit. You will most likely have to rig up some other higher rate charger for those BIG batteries. OR modify the charging circuit IN the UPS. They need to be charged at about 1 Amp or maybe more. See it is simply Charge over Time... 40 amps at 1 Amp will take 40 hours.. 40A at 2A = 20H & so on. If only 1/2 flat 2A over 10hours.

if you want the same voltage but with increased capacity connect positive to positive and negative to negative on each successive battery ---connected in parallel
example 6 X 12 batteries each of 200 crank hours will be equal to 12 volts and 1200 crank hours ( good for mobile fridges , winches , battery hoists etc)
if you want to increase voltage in the bank then connect positive to negative for each successive battery ---connected in series
with 6 X 12 batteries of 200 crank amps you will have 6 times the 12 volts which equals 72 volts and the current flow is increase from 200 crank amps to exceed the 1200 crank amps because of the electrical principles and formula I think it works out to be around 72 times the 200 crank amps ( I am sure that there are mathematicians out there that will adjust the sum to make it correct)
However I think that you get the idea
when charging batteries it is always positive to positive with the battery leads to the first battery in the bank and the difference is if in parallel the charger has to be big enough the charge at the accepted rate of the batteries ( 12 volts charge at 14.5 volts and around 20 amps an drop back as the batteries charge
when the batteries are in series it all changes and best talk with a good battery supplier as to how it is set up and if you need to change the charging circuit and equipment
not exact, to charge apropiate needs 10% more than nominal voltage. if not, will not charge the batteries.
And the charger its very important because you can over charge the battery.An example,if you have a 12 Amps Batteries each one if you put it in series will be 24 Volts.at parallel conection will be 12 volts but the double of Amps.
At serial connection will be 12 Volts the amps will be the same but the volts will be 24.
The charger at 12 Volts must be 13.8-14.5 DC Volts and divide the Amps in Hours.
The charger at 24 Volts must be 26-28 Volts. to charge well.
The charger for 12 amps batt example must charge 2 amps per hour at 6 hours = 12 Amps.(2 Amps Charger by 6 Hours Charging= 12 Amps.(Fully Charged.
3 Amperes Charger needs 4 Hours to charge 12 amps Batt.
5 Amperes Charger needs 2 Hours charging an a quarter
All of this is at DC Current.
A fully charged that is only about 12V indicates a a problem with the battery - dead / shorted cells, etc. You can always remove the battery and have it tested at Autozone or similar auto parts stores if you're unsure. From the info you've provided - my guess is that the battery is "done"
I have been installing car audio for over 40 years.A small adapter like you use to charge a phone,Doe,s not have enough amps in it to run the deck (Properly) When you crank up the vollume, The deck will cut out, You Can buy a bigger 12 Volt power supply from radio shack or the source that will power it (Properly) It should be at least 3 amp output .
How do you know the battery is good? Have you had a load test performed on the battery? Just because a battery reads 12 volts when using a volt meter doesn't tell you anything. You need to have the battery load tested. If it tests good, charge the battery to full charge. Put it in the bike and connect the negative battery cable. Using a good Digital Volt Ohm Meter that will measure amps up to ten amps. Set the meter up to measure AMPS. and put it in it's highest scale. Put the postive lead of the meter to the postive battery post. Put the negative meter lead to the postive battery cable that is disconnected from the battery. If you have a current drain, lower the scale range until you get a stead readable value. Then, disconnect the voltage regulator from the battery and read the current drain. Since you bike is ECM controlled, it will draw a little current but not over one amp.
Does your frig have 110, Gas and 12 volt setting? ... or is it auto select?
This is the way they should work ... if there is 110 Volts, it should run on 110 volts. The device is still controlled by 12 volts but the heat source is electric. If there is no 110 volts, it should switch to gas as a heat source. Same deal with the control, runs on 12 volts. If there is no electric and no gas, it should select 12 volts for a heat source ... same deal with the control. Problem with 12 volt source for heat is it GOBBLES up the power in your battery.
How is your battery? Do a volt test on the battery and the charger. Charger should run about 14 volts. Battery should provide at least 11 volts. If it is such that you can measure the acid, a good reading is 1200. Your charger can provide only about 15 amps charging power. Your battery should be able to provide up to 110 amp/hours.
If you do have electric and gas, it may not be your frig that is killing the battery ...
Hi. What size batteries you buy will be limited to the amount of room you have in the machine.
17 amp hour batteries are really a bit small for any mobility equipement. A lot of power chairs have 35 or 40 amp/hour batteries.
Buy the biggest that will fit into the available space.
Batteries are designed to perform a certain number of "charge cycles". If you run your batteries down by 75%, you will only get a small number of "charge cycles". If you only use 25% of the batteries capacity, you will get 100's of "charge cycles".
The best I have seen is 7 years out of a set of batteries. Short trips and recharging after each trip is the reason.
Good luck. Neil.
