It appears to use a small lithium battery that is replaced by removing a small screw and the cover. As for battery life, as with most items the battery life is going to be dependant on how many people use it and how often! I was using it daily for the past three months but now I'm home and won't use it till I travel again. So my battery has lasted three months so far! That's 90 days weighing twice to check accuracy! So at least 180 weigh-ins. If you only weigh once a week that would be the equivalent of over 3.5 years! So I think battery life is really difficult to nail down.

how long does a battery last? If I have not used it for more than a year will the battery still be good or do I need to replace it?

Depends how much you use it.I only use mine sparingly and the batteries have lasted for months. Use lithium batteries and they'll probably last a year.

Not sure exactly but it lasts a good bit...it's a rechargeable battery. I work.night shift and it's never ran out on me.

In my experience used as a backup for a house alarm system this type of battery has lasted for at least 3-4 years or more. I try to change it, though, in 2 to 3 years before it needs replacement.

It uses the 18650 batteries. They are sold on Amazon. Be sure to get the RECHARGABLE ones. They are much larger than the AA batteries.

I don't have exact time but I have used mine several hours now and still using original batteries.

Well, it's a rechargeable lithium battery, and lasts about 20 hours. Speakers without a power source, sound really bad.

It depends on if you're using them continuously. I would say you can get about 8-10 hours (though this varies). You can extend the life by removing the batteries when you don't need to use them. You can also buy replacement batteries, but they tend to be expensive so I would recommend buying new ones.

It comes with two sets of batteries. I'm not certain what type tho at the moment

This takes a standard C2032 battery. You can get them for about $2 at your local hardware store or pharmacy. They last about 1-2 years, depending on how often you use them or leave the device on.

It's a 6 volt 4.5Ah rechargeable sealed lead battery. My original was made by Power One and failed to hold a charge after 18 months. This battery represents about 75% of the weight of the light... lead will do that. I found a replacement on Amazon for about $10, which claims they need to be replaced every 3-5 years. I just ordered it, so no comment on performance. Here is the link: http://www.amazon.com/dp/B0006N61RW/ref=wl_it_dp_o_pC_nS_ttl?_encoding=UTF8&colid=O4ITN6WDQLMQ&coliid=I2MHNAW465GPTP

it uses AAAA batteries. A little harder to find than some, but not that bad.

The battery has a good performance. It works more than 5 hours, it´s enough for me.
