“Is it safe to leave a lithium-ion device in an air-conditioned room whose AC temperature is set at around 20 degrees C?”

(Answer requested by Evan Zanark) Sure. In fact, one of the oddities of lithium-ion cells and batteries is that they work best at the same temperatures where humans work best: Room temperature — 20C/68F — is great for both humans and Li-ion! But once you get up to around 40C/104F, both humans and Li-ion batteries…

New Zealand: Wrap Up

The previous New Zealand posts covered where we went and what we did — a uniformly good trip throughout. Most of the logistic and mechanical elements of traveling in New Zealand were also positive. As mentioned previously, phone and data service was seamless for us — no new SIMs, data plans, or phones needed. However,…

New Zealand: Last Day/Auckland

After a good night’s sleep and breakfast at Naumi, (see previous New Zealand posts), we checked out of the room, left our bags with the bell staff, and Uber’ed into Auckland for a day of pleasant, touristy sightseeing. We started at the Sky Tower, which offered sweeping 360-degree views from two different levels, as small rainshowers…

New Zealand: Christchurch to Wellington to Auckland

(See previous New Zealand posts.) But after the TranzAlpine train, due to both the distances and travel options available, it was time to begin the journey back. Points further south in New Zealand would have to wait for another trip. The…
