Laptop battery: Ni-MH 9.6V vs Li-Ion 14.8V?

Question

Rechargeable batteries

Hello habr!
I have an old laptop (Packard Bell C3300) with an almost dead battery. The battery is marked PC-VP-WP59/OP-570-76702.
Disassembled - 8 SANYO elements, googled, looked at ebee prices - it's cheaper to take a new battery.
I found out that batteries from Dell Inspiron 1200/2200 are suitable for this laptop. They, like Packard Bell, use Ni-MH 9.6V batteries, and on eBay, sellers sell Li-Ion 14.8V, and they write that they are compatible.
Question: Is it so? Still, a difference of 5 volts is no joke. Can there be problems with charging? Can a laptop battery really kill you?

Answer 1

No, they won't fit. Nickel-metal hydride and lithium batteries have fundamentally different charging algorithms, for which not only the software, but also the electronics inside the laptop are responsible. Different battery voltages are a secondary factor.
As an option: disassemble another battery with similar Sanio cells inside and replace them.

Answer 2

One of the four Chinese people on eBay replied succinctly: "It works." Well, we'll try.

Answer 3

The manual for the Dell 2200 says that it can work with both Ni-MH batteries and Li-ion. The laptops are very similar, I hope that mine can also work with two types of batteries.

Answer 4

Do not forget about the advantages of Li-ion over Ni-MH. The latest batteries require a full charge cycle and only, while Li-ion does not have a "memory" effect.
