Can a rechargeable 9 volt battery be used to power this unit or does it have to be a disposable battery?

Yes. Any 9 volt battery will work just fine. As a matter of fact, this is an ideal application for a rechargeable, since the meter is a low power device and is used only intermittently, it should last a good long time. Rechargeable batteries generally hold less of a charge than the single use kind and have to be replaced (recharged) more often than single use batteries, which can be annoying in some circumstances.

Yes, rechargeable NiMH 9V battery can be used. However, the battery consumption of this meter is so low (0.6-0.8mA) it is hardly worth the trouble to use rechargeable battery. Even if you use the meter one hour each day, a disposable 9V battery should last you over one year.

Yes you can use rechargeable batteries. NIMH Hybrid or Lithium are GREAT. I am getting NIMH for mine. There are some advantages. the NIMH and Lithium batteries are DRY Internally and won't leak and damage the equipment. Alkaline are wet batteries and can leak and cause damage. I have had many items destroyed over the years by Alkaline batteries. I recommend Hybrid because they don't discharge rapidly and keep 80% of their charge for 1 year. Lithium (LiON) are even batter but more expensive and not necessary as this device has a VERY low current draw. Lithium are better for high current draw like Laptops and Cellphones etc. and the additional cost is justified. Yes you can use rechargeable batteries. NIMH Hybrid or Lithium are GREAT.

You might have already found out by now 2weeks later, but it does come with a 9V power supply. It does not run on batteries. I own one. Previous replies are incorrect...

with a little fiddling you can add your own battery that can last many days. All you need is 9V and a battery socket for connection. I use a number of 1.5 V batteries.

Rechargeable battery...The unit can run from a cord or be detached and powered by the rechargable battery...it will last a good portion of the day on the battery ...say for the beach.

Bruno, thanks for the question. This unit up is solar powered and it has its own vendor supplied rechargeable battery.

You can use any brand of rechargeable batteries, otherwise if you use it much you will be wasting a lot of money on throw away batteries.

i have no idea if there is a 9volt battery in the unit. the pkg and instructions does not mention anything about a battery comming in the unit. you have to unscrew the unit very carefully or else you will easily strip and never get them off. find a jewlers screwdriver set. also, find a free image or photo site that you can post an image of the problem.

It can use rechargeable 9 volt battery just as any device using normal Duracell AA battery can also use rechargeable AA cells.

It uses a 9volt battery, but it does not come with rechargeables. I bought a seperate cord to plug into a standard house outlet. The little amp does have a plug for that. Hope that answers your question.

This is a disposable product. The battery cannot be replaced by the consumer.

No, it uses two AAA batteries and this is one of the main reasons I bought it. I use rechargeable AA and AAA cells and avoid 9v if possible.

Yes, the cheap battery that came with it died quickly. Yes, they now have a 9V rechargeable by Energizer. They have rechargers on Amazon for about $10.

It allows you to use a 9v device by plugging it into the wall, there fore no need for batteries. It is not a charger

Yes they run on 9 volt batteries and run on power supply that comes with the unit

Looks like the only option is to recharge it. I don't see any removable part where you can put a disposable battery.

This unit is powered by a small wall-wart type AC adapter, it does not have the capability to use a battery.
