I'm not familar with your supplier but the website says it's a KR808D style.
If you check out the model specific section here:
KR808D-1 there may be an answer to your battery problem.
I don't use the KR808D myself, but it has some good
reviews here. You can check out
the suppliers on the front page of ECF for reliable, fire-tested suppliers with good
customer service.
