[Mogul, XV6800 Accessories] origins81:
With new roms and gps placing demands on battery life, I opted to look for an alternative. Performance hacks can only work so much before your battery dies out when you have an 1100 or 1500Mah battery. I found this battery on ebay from a store and decided to go for it and here's my findings so far....

The model number I'm testing is HLI-P6800SL and will cost you USD48.55

*FIRST IMPRESSIONS*

1) Battery is exactly same size as the OEM, had no problems with fitting. Initially thought its increased capacity it would be make it a tighter fit, wasn't the case, PERFECT FIT!!!

2) Turned on my PPC without any hitches or glitches:)

3) Free shipping, makes this even sweeter...

4) Juicing it up, will fill you in with a much more detailed comparative analysis, my girlfriend is a true test of battery power

5) After some extended use, battery is still cool, haven't experienced any over-heating some users claim

*PRELIMINARY RESULTS*

Having spent a full 36 hrs with the battery...the results are encouraging to say the least. Do keep in mind that for Li-on cells to be fully functional, they need to go thru at least 3-5 full discharge-charge cycles and this is only the 1st cycle.

I followed the manufacturer's specifications about the initial 12 hour charge, also take into consideration that this test was conditioned, i.e. I dished out extra punishment, GPS ON for every trip, BT headset on for every call, backlight at 40% (which is pretty bright) and send/receive set at 5 minute intervals.

I consider myself a heavy-user during the day (less at night) with usage being split data and voice even. I receive approximately 40-60 emails a day (some with large attachments) and make out just about as many phone calls. So without much ado, here are my results...

Testing started 09:30 when I initially placed the battery 100% and ended 02:49 when it finally discharged 0% = 17hr 19m window. So in order to rate correctly and/or approximately I took the calculation values (credit hofo_mofo) of my 1500mah battery

Talk time (4.5 hr)

Current = Rating / Time

Current = 1500 mAh / 4.5 hr

Current = 333 mA

Standby (230hr)

Current = Rating / Time

Current = 1500 mAh / 230 hr

Current = 6.5mA

Run time based on my daily usage 09:30/100% -22:23/ 0% = 13hr 13min window

VERSUS 1800Mah

Talk Time = Rating / Current

Time = 1800 mAh / 333 mA

Time = 5.4hrs

Standby = Rating / Current

Time = 1800mAh / 6.5mA

Time = 277hrs

Theoretical 5.4 - 4.5/ 4.5 = 26% more power

vs.

Actual 17.19 - 13.13/ 13.13 = 31% increased capacity

I will be back to update my findings after 5 charge cycles and will note any increased or decreased performance, but for now very promising. If you use an 1100mah or any other type of battery, do the math and the numbers will pretty much tell you if it's a worthy purchase or not. I am not in any way recommending you purchase this battery, just sharing my findings. So until then....
