Any way to buy a better battery?

Did some searching too and only found two mAh flavors, 1500 and 1320.
I'm with ya', there should be a larger battery option.
Someone could make a killing if they made a solar trickle charger.
I could see it being a back cover replacement or build them into the cases for smart phones.
I thought I had found it too,
Amzer 3500 mAh Battery Backup Solar Charger For LG, LG Optimus M MS690 - Chargers - Fommy.com
I did a double take while looking at the product pics but was deflated to see that it was just a solar charger in the shape of an LG Optimus phone.

 

That's really cool regardless. Thanks for sharing

 

My wife got a good/cheap/almost useless deal like that without consulting me first .
The batteries were 1320 mAh instead of the 1500 advertised. The home chargers were delivering too much juice to the phones which made them useless while charging, and that rendered them useless in general because I wasn't going to trust that no damage was being done to the phones while they were being charged.
That issue rendered the car chargers useless/dangerous in my mind too.

All said, we paid about $16 and ended up with 4 USB cords because the rest of the stuff couldn't be trusted. This was from a Top Seller on Ebay too.
