Battery backup time is 1 min when capacity is 100%(4 months older

Estimated Battery Time is shown as 1 min even when the battery capacity is 100%
TV is the only unit connected to it. When the power is gone, battery backup is gone immediately. Till before 1 week, it used to show 170 mins when the AC power is on and 35 to 40 mins when the AC power is off. The UPS was purchased just 3 months back. Not sure what is wrong. If anyone has solution for this issue, please let me know
Thanks a lot

The Batteries are the most likely course of your UPS backup problem. The batteries cell may have been weaken with Age or loose contacts. Check to confirm the battery contacts are not loose, replace the batteries with good one.You can also check the strenght of the batteries by using a Multimeter and load to read the voltage of the batteries outside the UPS. If the battery voltage drops below 10V Dc on load the the batteries should be replace. Otherwise check the battery contacts.

Battery drains in 30 mins


Rechargeable batteries have a finite number of charge and discharge cycles and will lose their charge capacity over time, i.e. won't charge to 100% and gradually the charge reduces until the battery won't charge up at all. OR The battery shows a 100% charge but when the adapter is disconnected the battery drops off to zero capacity in a very short time. If the battery drops to an unacceptable charge level then the battery needs to be replaced.
Rechargeable batteries will fail if stored in a discharged state for long periods.

I have a problem in my dell laptop battery. I have charge alomost 1 hours and is show full battery and time backup is 1 hour and 30 min. then after 20 min. it shown 35 min. backup


The battery may be near the end of its usable life. As batteries age, they cannot store a charge as long as they used to. Also, if the battery is constantly being charged, this could cause the battery to lose its ability to keep a charge. The best option is to replace the battery.
Please rate my solution to let me know how I'm doing. Thank you!

How to program a woods TD1000 indoor timer


Here's how to set Woods TD1000 timer

This is older timer with backup battery. Plug in timer to see if battery will recharge. Display shows when battery is charged. No display, then timer is no good.

TD-1000 timer has 8 on-off functions per 24-hour day ...newer timers offer 7 day function with more programming choices... which may explain why TD1000 instructions are hard to find

Timer has 5 buttons + reset:
TIME MODE PROG HOUR MIN

Set time
Press and hold TIME > use Hour to set hour, Min to set minute
Release Time button ... correct time should show

Program: Capacity for 8 on-off times per day
Press PROG to set first ON time
ON and number 1 are displayed on left
Use hour and minute button to set ON time

Press PROG to confirm
Now, OFF and number 1 are displayed
Use hour and min key to set OFF time

Press PROG to confirm

When 8 programs are set, Press MODE key.
Choose Manual OFF. Manual ON, Auto ON, Auto Off

To use programs, select Auto ON

DST daylight savings time has to be done manually.
Press HOUR MIN button simultaneously > timer set up one hour
Repeat again and timer goes back one hour

Do not plug timer into extension cord > must be plugged into wall
