I remember, we did changed our computer battery charger twice already. To change charger is not that easy story in our part. I am hoping that this is just like a powerex 2700 which you can recharge it right away without worries. But the last time we change the charger took for almost 2 years of using before we change it. God really knew it that we had a hard time replacing computer charger if it happens to be broken. lol. Praying that the recent one will not give up easily but we need extra careful too in using our computer as a whole.
