Did you notice that the battery had heated up during its time on the adapter? If it was internally dead-shorted through battery deterioration it may not have permitted enough voltage to reach the PB's works. Otherwise, in my experience of PB 100 series (except the PB 100 itself), PB 500 and PB 1400 series, a bad battery simply acts as a capacitor-like buffer for the adapter, even if it nevertheless holds little charge. The backup battery, which is also a secondary battery (rechargeable), by contrast is extremely long-lived, but may take a long time to come good again if you do not have a serviceable main (or 'system') battery that reaches 7.5V under charge.
If it hasn't already appeared, you are fortunate that the TFT display does not have the common (and terminal) tunnel-vision effect that afflicts many PB 180s. (Trawl these forums for a mention of 'tunnel-vision'.) Have you turned on video mirroring from the PB's control panel? In System 7.5 and up it's called PowerBook Display, or something similar.
System 7.1 is a good one, and can be improved by retrofitting the software mentioned here. Just note that Finder 7.1.3 is not where the page says, but in Drag & Drop 1.1.1. There are also freeware add-ons that you can download. More memory is certainly a Good Thing. If it interests you, for the price of a PM, and postage to the US, you could have a free 4MB expansion RAM card for the 160/180.
