How long have your batteries been lasting on the ESP25? A year, two years, 5 years? I would like to know what to expect. I'm planning to use a 75 amp-hour marine flooded cell battery, but I would be interested in your response for whatever battery you are using. Thanks.

I have a marine battery on myESP25 and so far it has lasted about 4 years thus far and still seems to be working the last time I checked - about 3-4 weeks ago. Have not actually had to have it kick in but when I shut the power off to the whole house, I did notice it was ready to fire up should the water get high enough to kick in the pump.Not much else

I've had this for a little over two years. Battery "tests" OK, but it's hard to know how accurate that really is. In my experience all batteries test well until they suddenly stop working. I'm guessing I wouldn't get the time out of it now, that I would of gotten out of it two years ago. I will probably replace the battery in a year as preventative maintenance. I had purchased the Wayne branded battery they offer for this unit.

Hi, I have a marine cranking amps 750 and cold cranking amps 600 around to 2 years and I got it from costco for a good price.

I'm sorry we have only had our battery for a little over a year & used it once during Hurricane Sandy October 2013 & did t have an issue with a marine battery I think it is 75 amps. I took the book to a store called batteries plus & they gave the suitable waterproof battery with a 3 yr warranty. Hope that helps a bit.

I am using an optima sealed marine battery it is about three years old and still holding a good charge

Hmmm, I think I've recharged my batt's 14-16 times each... and they seem to be producing about the same flight times so far. Don't know how many cycles on average the batteries should last, but I would think they would/should provide good performance up to about 35-40 cycles ("educated guess"). Make sure the battery has cooled down to ambient temperature before recharging; helps them last longer. Also... try not to operate plane at full throttle for more than say ten seconds at a time. High long current drains are hard on a battery. Sorry I can't give more specific info. Hope this helps somewhat. Chris

I've had mine for about 2 yrs. but don't use it daily, maybe weekly and it holds a charge like new. I think there are 4 major factors discharge (rate, depth), temperature (high), charge level and time. All affect lifespan, Deep discharges, high temps, over\under charge, high\low charge voltage are the things you want to avoid.

I also agree with Andrew. I bought this battery and simply installed it and it has worked fine ever since (more than 3 months now). I went from about 6 hours per day of life to now about 12 under normal use.

I agree for me last around 40-50 originally. Over time I'm guessing due to battery wear its portability duration is greatly reduced. I've had mine a couple years with moderate to heavy use. Doesn't seem to last over 24 hrs now without a recharge.

The duration time u can use, normally 6 cells battery last for max 2 hours, for me 9 cells last for 3h and 20 minutes....

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've done 4 trips already averaging about 5 hours and my rechargebles still show full above the 8.3 volts. There' a built in battery alarm indicator from 6.2 to 8.3 volts. So after 20 hrs and 4 trips..its still going strong. Yes to your question....and longer. Im going on my 5th trip this sat and see if I can still get a full day. I have spare batteries jyst in case.

I'm using this battery: MK Deep Cycle Gel Cell 12 Volt Battery for Backup Sump Pumpsits expensive but worth it and it should last for 8-10 years. Its very heavy duty.

Good batteries will last about 5-7 days in my Phonaks. Obviously you unsnap the batteries when not using the aids.

I'm not sure of the life expectancy. I would say a couple of years for sure. I am very pleased with this battery. I had previously had a lithium battery. This one holds the charge longer between uses , charges really fast, and allows me to cover larger area per charge!

I haven't had Wasabi's long enough to know about them in particular... Just generically, a decent lithium cell should be good for a few hundred cycles or 3-4 years... generally lasting longer if stored about 50% charged and at cool (40-70F) temperatures. Storing them completely discharged (or allowing them to completely self-discharge) isn't a good idea. These things are somewhat unpredictable -- ask Boeing -- but most of us hope to get a few years out of them...

I guess it all depends on the battery and how often the pump will turn on. Get a GOOD Deep cycle marine battery and it will go for hours. I got it for peace of mind just in case the power goes out. Hasn't run yet, but neither did my AC sump.

I purchased new batteries (2 as they were so inexpensive & I plan to keep my phone for a while) after owning my phone for about 16-18 months. The original battery was lasting only half a day. I use my phone primarily for checking e-mails & some calls, very little online time. The new battery lasts all day or close to it with my usage. I would guess - as another reviewer posted - that you might get 4 hours of internet use. Buy a couple & switch them out. BTW... batteries losing the ability to stay charged is normal for any rechargeable battery, not just the HTC or other smart phones. Another option is buying the double size battery. Just a thought.

Don´t know how long you´ve been using it for. If it is 1-2 yrs max with a minor-moderate usage I suggest you contact the manufacturer. I did it once at the beginning and they provided a great/quick service. If you´ve used it for several years then you have to understand that all batteries have a life. Maybe you´ve drained it a few times and it´s over now.

I also suggest you read http://www.transformerforums.com/forum/guides-tips-tricks/24973-faq-definitive-thread-battery-related-matters-asus-range-tablets.html."" Lithium-ion (Li-ion) batteries typically have a lifespan of between 300 and 500 cycles. With moderate use, Lithium-ion batteries can be expected to deliver around 80% of their original capacity after 300 cycles or about one year of use."My is now 2 years old and looks like the battery and/or charger are no good anymore.

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.
