| I am really growing to love my hpcs...and find more and more uses for them but they would become infinitely more useful if I only had to recharge them every 3 or 4 days. Aside from adding an external battery is there any option to put inside the 880 that will give it 16 or more hours per charge?

| Rich,
Do you know what the cell type used in the 800/880 is?

| The picture all but ruled that out, other cells can be sourced though. |

| The cells are kind of rectangular, and there are 3 of them wired in series...each being 3.7V. They measure approximately 50mm long, 33mm wide, and 10mm thick. Here is a picture of them...
I was thinking of trying to build a battery pack using AAA batteries (9 total ) wired in a series-parallel configuration. Edited by Rich Hawley 2007-09-26 4:42 PM

| Beneath the blue wrapping are there 3/4 cells or is it one single chemical comartment in each of the three modules? |

| One single chemical compartment....something like the Sanyo Prismatic LION cell UF103450P. I think that would be a good match...

| Not worth the rebuild, not significantly greater in capacity...just something that could be used as a last resort if the BA11s were not available any longer.... |

| One good idea is to make an external battery with rechargeable batteries AA or AAA...

| What about rechargeable D cells? I see many that are 10k mamps. They are a little bigger than AA cells but you will need fewer of them. |

| Then again there are also some li-ion batteries for power tools that come in 9, 12 or a variety of voltages, have an acceptable case - would probably benefit with a spray of black paint and can be easily replaced. |
