My PSP battery got spicy after multiple years of inactivity. Not sure how to handle long term storage since it was charged when stored.
Every 6 months to maybe a year. My very original one just lost charging, and I’m yet to try and jump start it using a 9V just to see if it might res, so i got a replacement in the meantime.
I have so many handheld gaming devices and now tamagotchi with built in lipos. I can see them going bad in the next year or so. Somebody needs to make a multi plug system that you can leave a dozen or so plugged into just to tend the built in batteries.
Sadly only really works with lead acid and nimh. Lipo rig to keep track of %s, letting them drain enough and only then top them off slowly - way too convoluted.
I’d make an organizer of sorts and put dated labels on things and just check bi-annually.
Unfortunately I have probably a grand worth of RC airplane and Quadcopter lipos that are waiting to explode next time I charge them, since I haven’t flown in the last two years. I wish something better would show up that isn’t as delicate. I’m rooting for high density capacitors.
You are right. Organization and keeping a system going is the only way to move forward. Also, probably throwing all of those lipos away and starting over so that I don’t burn my house down. (I use flame proof bags when charging and keep them in pretty thick ammo cans, so hopfully they won’t burn down my house, but still.)
At least there are fancy dumb lipo chargers that you can hook up several batteries of same stats to and charge em in batches.
I have some of those for my tiny whoops and other 1 or 2 cell quads to charge a batch of them with my fancy charger. Still, I have to calculate the charge rate for the batch.
A multi-plug charging system would be great. It could be a strip of power outlets maybe? Call it “Strip-of-Power” or “power strip” even.
Heh. I do have a power strip attached to my shelf of handhelds. That isn’t the problem. If I just plug them all in all the time, they will charge to full and stay there. It isn’t great for their battery life. I need something that detects their charge and only stays on long enough to charge them to half full, then shuts off, and I need that for a dozen devices.
Charge to 50% - less strain on battery at this charge (3.7V)
Depends on how long you plan on ignoring them.
Gonna use it once a month? Yeah 40-60%s a good range to keep it in. More than a few months? Depending on the idle discharge, but probably want to charge it higher so it doesn’t go flat. 0% charge is a lot worse than 100%, especially for LiPo batteries.
I’ve heard 70% is best for longer term storage.
If I’m not planning to use a device for a while, I generally do 79% as well.
Except for my Nintendo DSi XL and 2DS XL. The original DS seems to hold a charge eternally regardless of what it’s charged to, and the 2DS will literally be dead after a while if I don’t charge it to full. I’ve stored it at a 100% charge and picked it up a few months later to find it sitting at like 16%. Makes no sense.
The exact level you charge it to matters less than what the battery ends up sitting at. Batteries are happiest at about 40%, but very rapid get unhappy the lower they go. The closer you can keep it to within the 40-60% the better.
Depends on the LiPo. I’ve had some go dead or puffy after being at 100% for 3 weeks, others survived 4 months at 95% in the woods (I fly FPV quadcopters)
Also swap out your PSP batteries regardless because they will almost certainly bloat! Mine ruined my handheld because I didn’t notice it.
