12/18/2023 0 Comments 9 volt battery rechargeable![]() ![]() life cycle of filtering components degrading, There might be also other issues about leaving the circuit on for extended duration like: If you leave a charged Li-Ion battery on the table you might find it empty after a surprisingly short time. ![]() So if unplugging the jack simply disconnects the battery that battery will stay fresh looong time. Another good thing about Alkaline batteries is that they have really low self discharge rate. I guess there is a switch integrated to the 6.35mm jack that turns on the circuit when you plug in your cable. (kinda opposite scale of what you have tested!)Īfter reading this thread I made some googling around and most people suggest that the batteries would go about a year for seldom use or six months if you play heavily. So if it was never used 1 battery per year is fair game. However there was a little tag about a setup inspection from early 2019. It came with the battery already in the compartment and I donât really know when it was put there. I decided to try out the blackcube 9V I got my first active bass pretty recently. The money isnât that huge an amount and if it works Iâm quite happy with my solution and if it doesnât not much is lost. I decided to just take the plunge and try it. Itâs still single use it seems and maybe like with the other kind of batteries rechargables arenât as good and consistent. I also found a possible reason why my info doesnât match up with I looked up Li-Ion but those werenât rechargables. Maybe not memory effect but the rechargable wasnât as effective as it was in the beginning. ![]() I was content maybe for a month and then it got worse and worse. My experience with NiMh rechargables is still bad. Donât know how I fumbled those two in my head. Then Iâd opt out and do the same as You are right. Even without the memory effect they donât last as long as the single use kind and while being eco-friendly it becomes too much of a hassle. Just buy a few 9v NiMh battery and a decent charger.įor those I have the same experience as does. Still I think it might be a good idea for eco sustainability⦠The batteries you linked to state that they are good for âe-guitarsâ maybe they would need less frequent recharging in respect to what used before but still most probably you wonât be using the full capacity of this battery with your bass causing degradation over time because of the lower cells not getting refreshed by full discharge and recharge cycles. I would love to see other inputs on that matter. I am super new to the instrument world and did not have a chance to analyze many amp circuits on market but I have used a lot of different types of rechargeable batteries and ultra capacitors in a variety of standalone systems. Single use batteries however has a much flatter graph over time! I hypothesized what voltage that might be for this circuit I know of This might be due to noise and/or cost reduction but the result is when the Vin is lower than what the circuit is designed for, the signal starts getting cut off and eventually canât be amplified anymore. However the amp circuits on a bass ( as seen here on MK 1 ) do not seem to have this kind of power supply circuits that would condition (regulate) the tension to always have the most efficient power. Li-ion batteries are designed to work with this kind of supplies and they have a longer curve of voltage drop during their life time.Ä«elow is the consumption curve of the battery you have linked to. This means the power supply circuit should regulate in a way to disperse the extra tension if Vin>Vout (by releasing heat) or pump up the tension if Vin ![]()
