Did your UPS/Bike battery got expired ?? Dont throw it you can again reuse it
Warning:This method is only for Lead Acid batteries,not for Lithium ion battery
STEP 1: things required
you can use water that available in your home,but distilled water is more effective
(click here for How to make distilled water in home)
2) Syringe (anything which pours water on battery hole)
3) Dead battery (be sure that the battery is not in popped condition)
STEP 1: Remove the top cover of the battery as shown in fig
BEFORE WATER FILLING
After Removing Top |
STEP 2: Remove the cap and fill with water
STEP 3: Now replace the cover ...now recharge the battery ...Recharge for larger time for eg if u are using 1 Amp charger then recharge the battery for at-least 6 hours.
Now check for the voltage
NOTE:1.recharge for at least 6 hours(1 amp charger)
2.for higher efficiency distilled water 3.kindly note that this time the u cant get the original rated (12.6)voltage.The battery shown here which has been refilled for the third time,so the output voltage reduced to 9.6v,but if doing the refill for the first time means you will get 12V max
