DM-1801 charger schematic avaialble?

[n1kk]

My charger from the day one out of the box, while charging never switches from RED to GREEN indicating fully charge.
I measure around 8.2--8.3 volts across the connection points of the charger and about
the same across a battery after charging for a few hours.

I would be interesting in seeing the schematic of the charger to determine what causes
the RED to switch to GREEN.

Thanks

Hi,

Don't bother with that crappy charger, check this out viewtopic.php?f=8&t=564

Ken,

‘A few Hours’ is probably not enough. The standard charger is very slow. It can take 8 hours to fully charge. You may need to leave it overnight.

Hi,

I had one of my charger with the same symptom. Since I replaced the board, everything's working as expected.

I ordered a TP5100 charger from ebay. Hopefully I'll have it next week. Shipped from
U.S.

I have stock board removed. Until the TP5100 arrives I am using my iMax B6 charger with leads
clipped onto the charging post.

the swap out took about 20 mins. The TP5100 is working perfectly.
Shuts off at the right voltage.
