How many years is it good for? Is like a regular battery 4 to 6 years?

Hi, Bob. The Mity-Mite should outlast your battery(ies) because you won't be using it day in and day out (at least I hope not!). I've had my Mity-Mite for about four years and have used it to jump start a variety of vehicles, including a riding mower, Toyota Tundra V8, the regular battery on a Prius, and vehicles belonging to friends. I use it five to eight times a year, so it doesn't get much of a workout and it does the job right every time I take it out of the box, as long as it has a full charge. So, I'd say yes, you should get 4 to 6 years out of it if you take care of it, don't over charge it, and keep it inside where it's dry and doesn't go below freezing. Hi, Bob.

Mine lasted 9 years then I replaced battery and it still works; hard to find correct battery. Got it finally from Interstate Batteries since it has bolt on terminals rather than a F2

It's has been over 5 years and now it needs replacement. Excellent compact unit that I highly recommend.

It has been awhile, but I recall that mine only lasted about 2-3 years. I don't know if that is typical.

We've used a few times a year since we bought...... So far, so good. No problems. HTH

it lasts as long as you dont use it. the battery does not lose its charge once it is charged

Phillyphil, the description of "3 to 5 years" doesn't mean that it has that amount of electricity supplied. This battery is very much like a car battery. You can use some, or all, of it's electricity when your power goes out and when the power comes back on it recharges back up. It will live this way for 3 to 5 years. When it finally dies, it will need to be replaced. Engineer David

I am not sure on that..I have never had any problems with mine. I have had one besides this one for about7-8 years and it still holds a long charge.

not very long, but it is OK. What I do is to buy some additional battery for it; I have 4 battery, I think it is too many. 2 battery will be good enough.

I use this battery as the backup power source on a cabin alarm system. I generally change it out once a year just for security reasons although in the past they have stayed in place for over two years and still functioned fine when tested. I realize there is not a continual drain on the battery for what I am using it.

Do you mean how many years before it needs to be replaced? Or, how long on a given charge? If years, I don't know but it should last longer than any lead acid battery. If you mean on a single charge, I haven't timed it but probably about 30-45 minutes for each battery (there are two).

Can't find it from the manual. Suppose the life span of the battery depends very much on usage of special features like the lamp and altimeter. Otherwise, I would expect two years the minimum acceptable life span.

my advice only buy when you need it as you need to keep charged up . in normal condition it may last 2-3 years at best it may be less i just got mine 2 months ago n still working .

I have a battery backup for my computer .I use the battery in that.The unit is plugged in to the wall so when I lose power the battery kicks in and gives me time to turn every thing off the right way.It constantly charges this way and is always ready.and as I have said, the last one lasted 3 years.This one is still fine and I expect it will do the same.I do not know about the warranty.I am sure it would not be to hard to find out.

Only Battery I use is Optima "Yellow top" longer life designed specifically for electronic applications and many charge/discharge cycles. It is very expensive, but you will be glad you bought it. My first one lasted 19 years. That's more than 4 conventional batteries.Blue top is for boating, red top automotive. Some peeps like a huge capacity by going with multiples of 6 volt. But this is the simple fix.

i'm thinking at least 5 years. my original unit was the "A" version and it went bad before the battery did. I had the original unit and battery 5 years.Didn't have to use it in back up mode to much.

I've had mine for just about a year... I'm noticing just a bit of drain on the battery life. I'd say it's a strong 10-15 minutes. That's about all you should expect out of 6V. At less than half the price of a 12V I still recommend it. If they had one with a crevice attachment and at this price I'd buy stock.

I haven't had mine very long so can't verify the information, but according to the specs it is supposed to last for 50,000 hours of use which works out to over 5 1/2 years of steady use. I don't expect something like this to last that long, but it would be a nice surprise.

From what I can gather these type batteries have a defined life. It seems under normal usage the s4 battery is only good for about 1 year. Heavy usage (recharging a lot) can reduce the the life more quickly. I plan to replace my battery at least yearly. I try and always keep a spare on hand because a battery ordered on line is so much cheeper that buying one on the local market.

I have had the system for about 5 years and haven't had the battery replaced. Usually 5-8 years depending on your particular situation.

I have had mine for about 4 years with no problems. Every so often I will buy a new one just to be on the safe side.
