I feel confident that what the title text means is that if the bag can hold a maximum of 100 batteries, that it turns red when there are 20 charged batteries left. After all, it's not like they're being depleted IN the bag (in theory. In reality batteries lose some charge the longer they're sitting idle), a full battery is taken out and an empty battery is returned. So all the batteries in the bag are either full or empty, none are in between.

 That version of the joke with the bag blinking at "20% batteries" is also in another comment. Sure, that could be it, since a percentage of batteries is mentioned in the comic proper. However, it is ambiguous. The bag starts out at 90% batteries. So would the bag start blinking when charged batteries occupy 20% of the initial amount, such as in phones — which is 18% of the space of the bag — or would it start blinking when they occupy 20% of the total space in the bag, which is 22% of the initial amount? Besides, batteries are not removed from the bag when emptied, as they still have to be carried. If the bag is 80% uncharged batteries, I think the bag is still just as "full" of batteries, as worded in the title text. Furthermore, even if you decide that it refers to "charged batteries" (a wording which does not show up in the comic), a battery may be stored while partially charged, which makes it unclear whether it counts as a charged or uncharged battery. If it counts as charged, then it provides less energy than indicated by its count, and if it counts as uncharged, it provides *more* energy than indicated by its count, and may not be picked up by Cueball when he's looking for a charged battery and doesn't known which of his backups he just put back in there without fully using. If it counts as a partial battery, say, 50% of a battery if it's 50% full, then all you're doing is counting the energy capacity of the backpack, which is what is in the article because it makes sense, but with the added ambiguity of whether you have started from the total amount of batteries the backpack is capable of carrying, or simply the amount it started with. Therefore the title text must be referring to energy, which makes the most sense given all of these considerations, and which would most easily allow an actual such bag to be built, if it all the batteries were somehow plugged into some machine inside which would flash red lights when at 20% of the total capacity. Now, while writing this I notice that "energy capacity" is also slightly ambiguous as technically a backpack may have the "capacity" to carry more batteries than are in it, which may be said to be the "energy capacity", however I still believe the term is easily understood by article readers as the energy-carrying capacity of the total of batteries inside the backpack when summed. Lastly, I warn that you do not confuse "capacity" with "capacitance", as that word sprung to mind in this context. [[Special:Contributions/198.41.230.94|198.41.230.94]] 14:02, 6 August 2017 (UTC)

 Having too many redundant backup devices can actually reduce the up time of the system.  This was seen at the Superbowl in New Orleans.  http://www.espn.com/nfl/story/_/id/9082144/relay-device-malfunction-caused-super-bowl-xlvii-power-outage-according-expert  It is also very dangerous to assume that your backups are adequate and that you don't have to watch the log files.  If somebody had been reading the logs, they would have seen the message that essentially said:  "I have reported two power surges and you haven't told me what to do.  Although these are not individually dangerous, one more power surge before somebody talks to me and I shut down the entire stadium."
 An optimist states that the water glass is half full, while a pessimist states that the water glass is half empty.  What an engineer really does is find out where the water faucet is so that he can refill the glass as needed.  (The original joke says that the engineer states that the glass is twice as large as needed.  This is ridiculous unless he knows how much water is needed and how much is available at the faucet.  The size of this glass is irrelevant unless it is too large to be handled easily or too small to transport water at the required rate.)
