Besides, the difference between 750ma and 800ma is minimal, the plug charger is sorry.Last edited by mike Steele; 11-16-11 at 01:19 PM.

True. The 700mah bb folding charger is working great for me.
It would be nice to find something at 500mah and see what it does for a longer charge.

- I used a 550 MA Motorola charger for the first few cycles till my pod showed up. My battery is great. There might be something to the low current theory. Most batteries, in my experience, like a slow charge. But most of my experience is with 19th century lead acid tech. I suspect the phone itself is capable of regulating the current, and that anything north of sufficient is just fine. I'd be interested to hear what someone who actually has clue one what they are talking about has to say. I'll consult a few sources.11-16-11 03:41 PMLike 0

- Hank, for someone who claims to know what he is talking about you can't even get the units right. Battery capacity is measured in (m)Ah, and current (the output from the charger) is measured in (m)A
As it happens there is a charging dock package on the official blackberry accessory store that comes with the "premium" charger (yellow USB tip) for use with the 9900, so it must be ok to use. Personally I haven't used the plugtop adapter with the USB lead as it isn't really long enough to use where I charge, so I still use old chargers I have from previous phones. Never thought to compare the output ratings.
My knowledge of charge/discharge rates is limited to LeadAcid batteries, since I work with them. On those a fast discharge can allow a fast re-charge, however a partial fast charge can give an illusion of the battery being at a higher state of chare than it is due to uneven charge distribution through the plate.
I know lithium batteries are a real PITA to charge correctly, which is partly why they are expensive, they need fairly complex battery management systems (BMS)11-16-11 04:32 PMLike 0 - I love when we talk about charging batteries.
SO many different opinions, no wonder many new people have no idea what to do!bowledbybold likes this.11-16-11 04:46 PMLike 1 - I've been watching this thread since it started and watching all the chit chat back and forth. I have no advanced knowledge of batteries and chargers... but I will say there is a difference with the little cube charger provided with my 9930 and the fold out prong chargers. When ever I charge via the cube it hangs at 95% for awhile... ok maybe a long time.11-16-11 05:51 PMLike 0

- I think so. A lot to people here noticed this too. Also there is a low frequency sound emitted from the charger. Some people can hear it but I can't. My dog can hear it well because he doesn't go near the charger. I think this is part of the package... No this is not an issue.11-16-11 06:24 PMLike 0

- Low and slow is the best way to charge a LI-ION battery.

The cube charger is the best way to charge your 99xx's battery. Argue about it until you're blue in the face..lol11-17-11 12:38 PMLike 0 - Low and slow is the best way to charge a LI-ION battery.

Thank you!
This is exactly why I prefer the 8530 charger over the cube. I know the difference is only 50ma, but I can tell a difference in battery performance.
