iHP-120's built-in lithium polymer battery

[Digital007]

I am aware that the iRiver uses a built-in lithium polymer battery similar to the iPods. Does that mean that the battery will disintergrate after 300 charges like the iPods? Before my iRiver I used to have an Archos Recorder 10 that took standard AA batterys that are readily available.

I would love it if someone could provide me with some tips on how to care for the iRiver's battery.

I read it was 5000 charges, and it doesnt have that "memory" problem, meaning you can charge it at any state and not worry about premature battery death.

Please kindly do a search, this topic is well covered.

There is an extensive coverage of this issue on this site.

Ipod uses a liuthium ion battery, iriver uses a lithium polymer battery which is better. According to Iriver, the battery will still have 80% left after 300 cycles. That means if you charge once in three days (4-5 h music a day), after 3 years, it still lasts 12 h. You can change the battery by your self (www.ipodbattery.com) for only $29. After 3 years, may be you are more happy to upgrade to a new DAP

iRiver H120 has lithium polymer. iPod has lithium ion.

The H120 will last longer.

doesnt the lithium polymer also make it un-explodable - the lithium ions are apparently prone to explosions. Also, I read that polymers do not suffer from memory, and ions do a little bit

Here's a quote from batteryuniversity about the pros/cons of lithium-polymer:

Advantages

* Very low profile - batteries resembling the profile of a credit card are feasible.
* Flexible form factor - manufacturers are not bound by standard cell formats. With high volume, any reasonable size can be produced economically.
* Lightweight - gelled electrolytes enable simplified packaging by eliminating the metal shell.
* Improved safety - more resistant to overcharge; less chance for electrolyte leakage.

Limitations

* Lower energy density and decreased cycle count compared to lithium-ion.
* Expensive to manufacture.
* No standard sizes. Most cells are produced for high volume consumer markets.
* Higher cost-to-energy ratio than lithium-ion
