I use an early '00s TI calculator daily. It's great for quick calculations that are a bit beyond my mental math capabilities.
I've considered these types of mods before. The biggest reason I haven't is the ROI feels impossibly low. A set of 4 disposal batteries last >6 months. A lithium ion battery lasts ~4 years before needing to be replaced. Doing a lithium ion mod would save me less than 32 disposable batteries before I would need to replace the rechargeable battery. It seems way way faster to just keep some disposable batteries in my desk, and not have to worry about charging or replacing a lithium pack. This is cool, but feels impractical.
- bxparks 3y agoYour TI calculator use 4xAAA batteries, yes? Why not use NiMH rechargeables instead of disposables? NiMH are so cheap these days that they pay for themselves after only a handful of recharge cycles. The other advantage of NiMH is that they rarely leak (I've never seen one leak). In contrast to disposable batteries which tend to leak and destroy electronics.
- causi 3y agoNot that your overall point is wrong but lithium ion batteries aren't that bad. I've have quite a few over a decade old that work just fine.
