how long does the internal battery last in it before replace a new one. And is the battery replaceable. Thanks

My last one lasted at least 4 years. Didn't replace the battery because someone stole it. New one work great. Started my Hemi the other day.

Have never had to replace. I would imagine you could do it with some difficulty, but it will probably be cheaper to throw it away and buy a new one. I think the quality of the battery is better than the rest of the unit

I purchased mine in 2007 and only recharged when it dropped below the green (which was not often). I never had a problem getting the battery to charge to 100% until recently when I accidently hit the inverter ON switch before closing up the car and drained the battery. Now it will only charge a little over 50%. I primarily use this for the compressor although I will likely buy a replacement just for the peace of mind of having a jump start capability. I considered replacing the battery as well but figure it probably isn't worth the hassle, but if anybody tried it, let me know how it turned out!

It is not replaceable. And the battery life is horrible. Only around 2-3 hours.

It has an internal battery, but it is not servicable. The battery is listed to be good for five years.

It is a rechargeable internal battery not replaceable. Battery lasts a long time, lithium ion I believe.

Yes, the battery is replaceable. I keep the unit in the charger 90% of the time but when I use the unit on battery it lasts about a couple of hours.

the battery is not replaceable. make sure you refer to you're owners manual. mine had the same problem initially. its important to let it run dead a few times. it will explain everything further in manual.

No, the batteries are not replaceable. Based on my experience, they will break long before the batteries die so battery life will not be an issue.

I've been pretty happy with mine. Quick readout but I couldn't figure out what type or how to replace the battery. Mine still is working. I bought it last November.

Battery will last over a year ... just put a new one in it before you leave.

I have had the unit since May 2012 and have had to replace the battery once. However, the battery is the "coin" style battery and can easily be replaced. I hope this helps.

I don't know the life span of the battery. I still have the same one that came with it when I bought it back in December. Maybe someone who has had one of these longer could give you a better idea about the battery life.

It is a built in Lithium battery. So, I'm assuming no way to replace it.They are asking me to assume the charge of shipping and send a $9.95 check for possible repairs because mine stopped working.That would probably be what you would need to do if yours needed a new battery. Since I've had mine less than 6 months I'm not a happy camper.Probably will not send it back. (This is their idea of a guarantee, I guess.)

the battery is not designed to be replaceable. I have read that some people have opened the back and found that the battery is soldered in.

No internal battery to replace from what I could determine. I am very pleased with both the ease of istallation as well as quality. And the customer service was quick and knowlegable!KA

No, the battery isn't replaceable. Despite that, it lasts a very long time. I bought it over 2 months ago & it's still going (my cat plays with it everyday). It's worth getting even though the battery's not replaceable.

I have not had to replace the battery for the last two years. Since the price is so reasonable, I would purchase a new one instead of replace the battery. It is nor worthy replace the battery. I hope that help.

No it's not replaceable but the battery won't stop holding a charge for many many years. By that time you will have moved on. Also It has an internal overload shut off so you won't fry the battery.
