I will soon run out of alkaline batteries and would like to replace them with nimh or the like. Some of the nimh will be used in a marine environment. The Coast Guard and others entities warn against using lithium rechargeables in this environment. A closed boat in the sun can generate a lot of heat. I’ve never measured it but it can get quite hot inside. Question: Are nimh batteries any more or less susceptible to heat than the usual lithium’s? Are nimh any different about excess heat than alkalines? I’m trying to make things as safe as possible on the boat. Most marine recommendations are to use alkalines, though I wish to get those out of my routine as much as possible. Thank you.
Been out of touch of NiMH chargers for a while but looking to get a portable one. Anyone know if the BQ-CC87 is indeed a smart charger? The product page shows an image of the box stating quick charger.
The little light attachment looks cool. Anyone know where to buy one? I couldn’t find any info on it.
Edit: In the description it says “Charging times shown in the table are only indicative and can vary depending on temperature and battery status” so I guess it is smart?
I also found a photo of the back showing output as 0.5A x 4 (AA) and 0.25A x 4 (AAA). Anyone know if those currents apply regardless of the number of cells? e.g. if populated with only one AAA will it be charged at 0.25A?
Thanks ChibiM. Done a bit more research and does look it is smart in that current is varied “depending on temperature and battery status”. I’ve edited my post above.
I don’t really need another charger but the powerbank feature is interesting and looking to put all the Tones I’ve accumulated to good use.
Based on the charging time table, it looks like those current values apply if you charge all 4 cells simultaneously. If you only charge 1-2 cells, charging times are cut in half, which would indicate that current is doubled, so a single AAA cell would be charged using 0.5A current.
Not many that I have personally, but my current clamp ( uni-t 210E) starts reporting wrong numbers when the cells are under ~1.45V, it’s really bad. My meteo station modules seems to have a high cut off, although not as bad.
I’m wary of the potential self discharge rate of a li-ion cell coupled with a voltage converter, but more importantly they are extremely expensive.
