We use a small battery like those used in a trailer breakaway system I might charge it twice a month at the most

I power the unit with the smallest storage battery I could buy, and I use a small trickle charger to periodically charge it and keep the battery charged. I've never let the battery go for more than 2 or 3 weeks without the trickle charger. This works for me because the fence is close to the house. I keep both the Zareba and the trickle charger in a plastic bin with a snap-on lid, with holes for the fence wire and the extension cord for the trickle charger. The plastic bin protects the battery and charger from the weather.

We use a large 12 volt truck battery and it maitains a good shock for 2 months. At the end of the 2 months we put in a fresh battery and recharge the other one.

Several days. I usually remove the battery and charge it once a year so that the solar just has to supplement charging.

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.

I change mine about every 6 months, but I only use it at work. It doesn't get everyday or all day use.

I bought my battery as a replacement and I charge it about about every four days. I haven't had a battery strictly as a backup

The pendant battery can and should be charged about every 30 days, it is charged in the base unit where the spare is stored. Storing the battery charges it and keeps it charged until changed with the second battery.

Good question. I never had to replace battery since it is rechargeable. A personal bad habit is that I watch tv all night. So I've experienced normal charge can last over 12 hours of continuous use. Then it recharges during the day while I'm working. Also on weekends I use it during the day as well, but between uses I slip it back into the charger. I hope that helps.

I changed the batteries on mine after more than a year of use; the stock batteries were just generic. I haven't changed them again after replacing it with good batteries over a year ago. I use mine about three to four times a week for several hours at a time. Just switch off when you're not using it.

I charge mine 24 hours once every 2 or 3 weeks when it gets slow. Even if it is dead it should pick up enough charge to run within 30 to 60 minutes. If not either the charger is not charging or the handle is not taking the charge. These are cheap enough it is more cost effective to replace than repair if anything is failing.

I go thru maybe 2 fresh batterys a year. I say fresh, I suggest always right off the rack. also useage is important but I have been very happy.

I know this was asked in 2010, but it takes time to answer this kind of question. I've had mine since 2011. The battery is showing wear and needs to be charged more frequently than when it was new. When new, I would charge it once every month or so. Now, I'm charging it once or twice a week. Based on how often I recharge the razor in 2014, i'd expect it to last another 1-2 years before needing a full replacement. So, the guesstimated longevity of this razor could be up to 5-6 years. My use is every weekday as a dry shave, never wet. Not used on weekends. I wash the razor about once every 2 weeks and it gets oiled nearly every shave.

I never had to replace my battery in ten years of use. I would use it four or five times before charging. I believe it might be a chore to replace, if you have not done it before. If you will oil the blade every other use, it will stay sharp. I decided to just by a new razor instead of a replacement battery was a better option.

I use mine about once a month. Never had any issues with the battery and I have owned it for over a year.

I've had mine for 2 years. It came charged so I've never charged it. I test it about every 2-3 months & it's still working; so I don't know that you'd need to charge it very often. Any research I've done indicated to charge it about once every 2 months with minimal use.
