So for my Falc, if I am using it, there 's a chance of it leaking - because they are not turned on but connected.
So I have to NOT use my Falc, then the batteries are used. :wink: :lol:

Heh, that's a nice reversal of the norm :D Leaky Falcon? No problem, just turn it off for a few days!

I noticed my TT seems to lose time a lot. It has a new tadrian battery. I've been using wongck's excellent Synctime to grab my ISPs NTP time every time it boots, works great :)

I replaced the battery but I have the same problem. A lot of times between power-ons it loses the time. Haven't had the time to look into it. Battery is fine.

Some TTs need 6V batteries, some 3.6V IIRC.

The one I replaced was the original battery. 3.6V. Replaced it with the same type. Need to check the circuit.

So embarrassing. Opened up the TT again and checked the wires from the battery. Looked OK. Checked the voltage. Got nothing. Took the battery holder out and voilà. I have my battery in a holder with an on/off switch. When I put the case back on the SCSI ribbon cable must have touched the switch and turned it off. :oops:
