Battery charging

Hello

 

I have this battery:

it has 6V, 1.3Ah... I don't have a charger... on the side says:

 

cycle use charge 7.25 - 7.45V

Trickle charge: 6.8 - 6.9V

and something about 0.4A

 

why won't my phone charge?

HI I NEED HELP! PLEASE?

;-)

Just kidding. This is scraping the bottom of relevancy though.

Could you perhaps point me to a good documentation source for charging a 3.6 V battery in an old Nokia? Or could you solve my problem directly for me?

My dad is about to go walkabout in the south of Europe. He bought a 12 V photovoltaic power source that folds like a wallet. He seeks my help on the simple stuff, like mechanical compatibility of connectors and pinouts. And soldering.
