#9 VOLT BATTERY FULL#

It's pricey at $131, but cheaper over the long term if you've got lots of pedals that you use disposable batteries in often. It beats using individual 9V batteries, because there's only one battery to charge, and it beats using AC, because the battery power is clean and you don't have to run electrical cords to outlets. Musicians might be interested in the Pedal Juice battery, where a single rechargeable battery pack can supply 9V of clean power to all your effects pedals via a daisy-chain cord. The energy of 9V alkalines seems to be 2.8-3.7 Wh, while 'Heavy Duty' 9V's are 0.4-0.9 Wh. Lithium-ion (rechargeable): 7-7.5 hours.A photographer tested various 9V batteries, taking one time-lapse photo every minute, and here are the results. Performance of different kinds of 9V batteries. You can't charge a 9V Li-Ion battery in an NiMH-only charger. For 9V Li-ion, here's an $8 Li-ion smart charger.

For 9V NiMH, see my list of recommended NiMH chargers. Most chargers don't handle 9V-size batteries (or don't handle them properly). Be warned that 9V-size NiMh batteries are actually made up of 2, 6, 7, or 8 separate cells, and if one cell dies then the whole battery dies, so 9V NiMH batteries are much less hardy than AA and AAA rechargeables. For musicians' effects pedals, see further down this page for a special product for that purpose. Your choices are listed in the table at right. Lithiums have about twice the capacity as NiMH, but of course they're more expensive. 9V rechargeable batteries come in two flavors: NiMH and Lithium. I'm skeptical would ever provide good performance, but I haven't tested them so I can't say for sure. Usually work well even with the lower voltage because lithiums have such a high capacity. These will often be good too, but some power-hungry devices might do worse with 8.4V than with 9.6V. It's rare, but will always provide good runtime and performance. In the rest of this discussion, '9V' refers to the 9V size, not the actual voltage. An alkaline 9V is really 9 volts, but a rechargeable '9V' battery is initially 9.6V, 8.4V, 7.4V, or 7.2V, depending on the model in question.

'9V' is the physical size/shape, not the actual voltage.

For chargers, see the text of the article.ĩV Rechargeable batteries (NiMH and Li-ion) Voltage is from either product description or my measurement. Capacities as per manufacturers' specs I haven't verified that they're telling the truth. The battery will work, but the indicator will display inaccurate results.9V Rechargeable Batteries Capacity/voltage These indicators are calibrated for alkaline 9 volt batteries, which, by design, have a higher initial voltage level than a fully charged rechargeable battery. If your device has a charge indicator, this battery will most likely not show a 'full' charge when installed. Please view the datasheet or give us a call at 1-80 for further information.

#9 VOLT BATTERY FULL#

If your application absolutely requires a full 9 volts to operate, rechargeable batteries may not work for you.

Rechargeable batteries, like this 9V-size Lithium Ion battery, are rated at a lower voltage than their Alkaline-based alternatives. Important note about the voltage of this battery: Charging this battery in a NiMH/NiCd charger will void your warranty. The charger we offer that will charge this battery is our 2 Bank 9 Volt Battery Charger.Ĭharging this in a charger not designed for Li-Poly batteries will cause fire or explosion. You need a charger designed for Li-Poly/Li-Ion batteries. Given the technology behind these batteries, a standard NiMH/NiCd charger will NOT charge this battery.
