how long does a watchdog battery last my battery is 10 years old

If properly maintained by checking and adding distilled water every 4-6 months it will last 4-7 years

I believe it is probably time to get a new battery, 10 years is a long time, I replaced mine after 5 years.

It can last 4+ years if properly maintained which is clear that you are doing. Great Job. We do recommend that after 10 yrs you do replace it proactively. You can call our customer support line at 800.9910.0466 ext 3 if you are in need of further assistance

Best thing is to avoid watchdog . Batteries are hassle and last average of two years and very expensive.

No.....battery is sealed and has a 10-year life, and will chrip every 30-45 seconds when battery is low at which time unit needs to be replaced. No maintenance required over the 10 year period.

Operates entirely on 10-year battery. After that, you can buy another 10-year battery for $8.

The watch uses a maxell CR 2032 battery. Typically it lasts 9-12 months but that is dependent on your usage. The watch automatically goes into a power saving mode when it's not in the middle of a test. An icon comes up when you are running low on battery and then you have 30+ days to change it.

The battery is not the issue. Smoke detectors should be replaced every 10 years (actually 86,000 hours) whether or not they have replaceable batteries. This is why the unit has a 10 year battery. So that it will be maintenance free for its entire lifetime, and you will be forced to replace it after that.And yes, it probably does make them more money, but it's a matter of statistics. Your particular detector may still work at 15 years, but the vast majority don't at that age. It's a matter of risk management. I'd hate to loose my house (or part of it) because I tried to stretch $20 out another few years. The battery is not the issue.

Its a pretty long time. I charge it occasionally, but it has never died on me while I was using it.

Lithium 2032 watch battery - requires 2 of them. Don't assume the ones that come with it are fresh... they went dead in about a year with mine. Bought fresh ones, and they've lasted almost 3 years (so far) for me.

I have not replaced my battery yet and I have had the night rider 650 for almost 18 months. I use it almost daily and love the light and rechargeable battery. I have dropped it multiple times and had a serious wreck in Jan of this year and seriously scraped a section of the plastic but it takes a licking and keeps on ticking. I am buying one for the wife.

The battery that came with it lasted about a year. I bought a replacement from my local Mac dealer and it holds it's charge longer, it cost a bit more but worth the extra money.

I'm still using the batteries that came with my chainsaw, my tree-trimmer and my weedeater. I made sure to buy items that all ran on the same batteries. I think my oldest battery is 3-4 yrs old. I did lose one because I dropped it on concrete. I am just now reaching the point where I need to replace my batteries. I use them year-round. I keep the charging all the time so on evenings or weekends I always have batteries to go. My batteries still work but it seems they don't hold a charge as long. So I would say 3 to 4 years.

i have it over 5yrs still works. i had to replace the watch battery. PITA to replace the watch battery but the voltage was too low and not reading the HR. the watch and the strap are 2 different batteries.(2025 & 2032) easy batteries to find at local pharm chain store. i replaced both at the same time and all good.

Mine is near 3 years old. Battery life is certainly shortened now (probably 10-12 minutes run time) but zero complaints about its performance. Gets used a few minutes every few days. I have been guilty of leaving it on charge a few days over the years. Certainly been a good value so far. Will likely built my own battery for it when the run time is unusable.

I have had a Watch Dog Special sump pump for at least 15 years and the pump still works fine. I am replacing my main sump pump soon so I decided to replace the Watch Dog as well (after this long, better safe then sorry). I have replaced the battery twice in that time, which is better then I expected (like car batteries, these things will always wear out). I am VERY happy with the unit as it has saved me a number of times through the years!

Battery life depends on how much time unit is in alarm condition. If it never goes off, they'll probably last a year, but it also depends on the batteries and the environmental conditions.

I will check date on battery box and respond, the batteries are suppose to last ten years. My use of batteries are to power Fire and smoke detectors so I expect 120 months of performance.

My battery has lasted a few years. It alerts you by the lights blinking red then green.

my batteries had a " best by" date on the side of each of the batteries. The date was 4+ years from the date of purchase. as I use 10 at a time to replace smoke alarm batteries this was an adequate shelf life for me.
