No disrespect, but BL-5J form factor Li-ion batteries cannot produce 245mAh. The higher capacity batteries of ca. 1500mAh achieved this by being slightly thicker. So, if your battery is good, it will be between 1300 and 1500mAh. Many batteries with inflated capacity claims oroved to be <1000mAh but some were ok. See the old and still interesting thread on the subject.

Have been running PolarCells for years now and I love them. I buy at a new one at least every 1-2 years though.

Yeah, I know the capacity is not true, it is about half of stated one. Besides this details, the DX battery for N900 works.

I use double-pack batteries so when my polarcells went from around a combined 3000ma/h to about 1000 in three months and used up completely lasing around 20 hrs in a N900 mostly on standby with a few short calls or checks of email I had no recourse or warranty as I had seriously modded the battery. BTW I didn't apply any heat to the battery when soldering the tabs.
I am actually soldering a double cell battery today from fake Nokia BL-5Js so we will see how they last.

Thanks, all, for your responses! Though I must say I'm still a bit confused, as a lot of the reports seem to be conflicting. I guess that's the nature of buying batteries...

Anyhow, I ended up ordering this ONITE battery, which seems to have gotten relatively positive reports. I'll try to remember to report back my experience once I get it and have tried it out...

For anyone using mugen battery cover, the 2610mAh LG (BL-54SG) batteries fit near flush in the back of the cover. With the battery sitting in the cover, I can close it without any gaps around the case.

Food for thought

Really? And the terminals match?

It looks like it will not match from the pictures.

No, you would need to make your own connector. I'll take some pictures when I make mine
