Li-ion vs. Ni-MH

[MistaTastyCakes]

I just got an older lappy, and it supports both Li-ion and NI-MH batteries. What is the difference, and which is better? The laptop came with a Li-ion but the battery was DOA and can't hold a charge.

Any info is helpful, thanks!

Li-Ion is light, likes to be topped off.

NiMH is comparitivley heavier, likes to be charged full then used until dead, then charged again.

other than what FishTankX said, I found that Ni-Mh is priced considerably lower than Li-ion .. and with the right charger, they charge a bit quicker too .. they both should last about 1000 charges (that's around 3 years for normal laptop usage ...).

it's all up to you

Allegedly, the Li-Ion has a higher capacity that is designed to be charged without the "memory effect". If you like to keep your lappy topped off all the time, Li-Ion is the way to go. However, they are just that more expensive. NiMH is a good deal, and they're decent batteries. If you can afford the Li-ion, go for it.

I think Li-Ion also gives out more heat.. could be wrong though

Thanks for the help all.. I'm going to go w/ Li-ion.

Ummm, don't Li-Ion have different Charging Charateristics over Mi-Mi batterys, I would make sure the chargers can charge both of types of batteries..

Both are compatible with IBM Thinkpad 390E laptops, according to multiple sources.

Both NiMH and Lion batteries can be topped off

Nimh does not have a memory problem and can be charged even if not fully discharged.
The memory problem was mostly a NiCad battery problem.




Please correct me if I am mistaken, I am not really a batteryphile

You are correct. Ni-Mh needs to be fully charged then discharged about 3 times to "set" the batterys memory, after that it is fine to charge and discharge as needed. Li-Ion just do as you like.... theyll take anything. I'd always take Li-Ion due to the fact it's lighter, and stores more energy also.
