| Jun 19, 2018 at 16:43 | comment | added | Ian Bui | @JYelton, maybe I just have bad luck, but I haven't had great experiences with rechargeable household batteries. It's been awhile though, so things might have changed. I'll take it under advisement. | |

| Jun 19, 2018 at 16:40 | comment | added | Ian Bui | Not that it matters since I think I got the answer I'm looking for from discussion of @Drew's answer, but the candles in question are: 2 of these: target.com/p/… And 1 each of these: target.com/p/… target.com/p/battery-operated-led-candle-white-evergreen/-/… target.com/p/led-pillar-candle-white-3-x4-threshold-153/-/… | |
| Jun 19, 2018 at 16:39 | comment | added | Ian Bui | @laptop2d, yes I have an ammeter. What I don't have is an ammeter that logs/plots how it changes over a 24 hour period as the state of load changes. My question wasn't with regards to the nominal draw, but what the peak draw might be, especially if spikes occur during state changes. | |
| Jun 19, 2018 at 3:14 | comment | added | user57037 | Yeah. I don't see any real way to estimate the current. If you just want a number, it is probably around 20 mA per candle. But that is a guess, not an estimate. | |

| Jun 18, 2018 at 17:58 | comment | added | JYelton | A comment an an aside from my answer, if your only goal is to avoid purchasing and replacing batteries often, you might consider simply using rechargeable batteries. This would avoid the hassle of running wires and connecting them to the candles which I presume do not have a DC input jack. | |

| Jun 18, 2018 at 17:48 | comment | added | Ian Bui | If it also helps, I bought them all from Target last year and I think they still sell them. I'll post the exact models tonight. | |
| Jun 18, 2018 at 17:46 | comment | added | Ian Bui | It's on the order of several weeks or months. I've never counted unfortunately. The timer does go on a cycle of 5 hours on, then 19 hours off for each day. | |
| Jun 18, 2018 at 17:20 | comment | added | user57037 | If you run it 24/7 with 2 AA batteries, how many hours do the batteries last? This will give us an idea of how much current it uses. | |
