You could have mentioned this earlier and saved a lot of messages. :)
If the voltage ratings are the same, and the pins for the battery are
the same and it fits, there's no reason not to try it. It might have a
larger capacity than the original. Just make sure the voltage is the same.
Here are the specs:
Original battery
--------------------
Dell Battery Module Type 75UYF
Rechargeable Li-Ion
Rating 14.8V - 3800 mAh
Charging Current 3.5A
Made In Japan
Replace with type: 1691P, 5081P, 53977, 3149C
New battery
----------------
No manufacturer name, logo or country of manufacture
Equivalent part numbers: 66WHR, 312-0009, 312-3250, 1691P, 5081P, 53977,
3149C and a few others
Li-Ion
Rating 14.8V - 4460 mAh
I am a little disturbed that theres no manufacturer name or logo, plus it
doesn't state rechargeable. Is it safe to assume it is rechargeable?
I compared the two batteries. Physically they are almost identical. The
connector slot (which can be seen in the picture here:
http://www.digi163.com/battery/DELL-laptop-battery/Dell-Latitude-C610-batte… ) is
slightly different on the newer one. It's the same design but the
gaps between the connectors is visibly smaller, only by maybe a millimetre
or so. The voltages are the same so I'll give it a try over the weekend.
