Impress Battery problems

[svfd450]

Hey guys,

I have a Impress Battery (HNN4003A) That I had bought recently and have not used in awhile. While attempting to put on the charger today I got a flashing red light saying it is nonchargeable. Now I know this is a brand new battery but is there something I did wrong? and is there a way to bring this back to life?


thanks,

steve

What is the date code on the battery? If it's still under warranty, get it replaced. If not, fork over for a new battery.

I charged another battery on my Impress charger then tried the Impress battery again and it seems to be charging (steady red) At this point ill cross my fingers!

When the Li-Ion batteries get down to real low voltage they can sometimes be very difficult to charge on the Impres charger. Another option would be to charge the battery in a standard rapid charger for a few minutes to bring the voltage up just a touch, then cycle it back to the Impres charger.

I can't stress this enough--- do not store dead Lithium Ion batteries! If you know you won't use it for awhile, charge it to 50%.

just to provide an update...

Can charge the Impres battery now (getting steady red after a long steady amber) but will not enter into 90% and fully charged state (no flashing or solid green light) it was my fault for storing the battery in a unacceptable condition but i thought i would provide you guys with an update. Escomm, can you FULLY charge an Li-Ion Impres battery on a standard charger??

thanks again!

Good to know on the storage of the Impres batteries.
Just got 8 HNN4003 ( date code 2005) in from customer who said they would not charge,taken out of battery cabinet after 4 years of storage as spares.
Same symptoms as above.Will try putting some juice to them.
