I have an old-ish laptop that only works on AC power because the battery is old and no longer holds a charge. I live in Christchurch New Zealand where there has recently been a number of very large earthquakes. During one of these earthquakes my laptop was thrown from my desk to the floor and now does not respond at all when the AC adapter is connected.

Given that the laptop is not responding to power, is there another way I could charge a replacement battery for it as I don't currently have funds to repair the AC adapter on the box.

My research would suggest that this isn't possible as chargers need to take into account the specifics of the model of battery being charged
