I have had my RBC109-UPC battery in service for a year and a half and so far, so good. According to the digital readout on my UPS, the battery is still at full capacity. In my opinion, it is well worth the asking price.

You can't answer that question because it really depends on your usage patterns and also how often you lose power and run off the battery. I've had UPS batteries that have gone bad in a year, others have lasted over five. Same APC unit, same APC batteries. No issues with the battery in question so far, but it's only about 6 months.

The batteries have a life of 3 to 5 years. This is based on the batteries being kept in a good state of charge as well as being used in a appropriate temperature. The biggest factor that will determine the live of a battery is the temppetature. As the temp. rises the life goes down.

My original battery lasted about a year, too. I think it is time for you to buy a new battery, but that seems to be a problem, too. I have bought two that will not charge properly. I am about to return the second one. Amazon issued full credit for the first one I returned in less than 30 days. The second one never charged. I wish I knew how to test the charger just to be sure; however, from reading the reviews on the replacement battery it is obvious that many people are having problems with these batteries. It is a good vacuum, but the replacement batteries are a big problem. I would look for another brand vacuum if I had it to do over. My original battery lasted about a year, too.

Normally, the expiration date on batteries (or anything) means the date on which it is sold. The product, especially batteries, lasts long after the expiration dates, and the batteries will have their usual life of whatever is on the package. However, try to store them in room temperature, without extreme cold or heat. Hope this helps.

How do I find out what is wrong with this battery? I did not know that you aren't supposed to use the regular battery tenders on these kind of batteries and I left it charging for a couple of days and now it is beyond dead. So if the tender didn't kill it, apparently (also read just now in the questions section) if it drops below 8% charge it is no longer anything but a paperweight? So tell me now if I should just go out and buy a new battery after wasting my money on the 1 ride I got out of this battery.

Hello Linda. I bought this battery just last year when the original died of natural causes. At most, this sucker last me about an hour to an hour and a half after it's been fully charged. Might not seem like much mind you, but I tend to use the internet a lot and stream things online, and different pages up at once. The less you use, the longer it'll last bit I was reall happy when I got it. And instalation is pretty simple. Let me know if this does/doesn't solve your riddle. I will try again for you. Please have a good evening.

Says "18 AH" on the side of the battery. I bought 2 last year about this time......by July they were both dead...forever. Your choice and your money. My opinion is they suck.

I've only had it for a week, so no battey problems yet. It lasts my whole 10-hour work day on a full charge. There aren't any instructions included abot replacing the battery, but it looks like someone else responded and said it IS user-replaceable.Li-ion should last for years, but good battery maintenance will help extend the life. For at least the first 10 cycles, I charge it fully, then drain it completely. Don't recharge when it drops to 80%, 60%, etc. The performance doesn't suffer at all even when it is almost dead. That should help you get the most life and best performance.

Can't really help much there - I do know that dissimilar batts generally don't play nice in the sandbox. It's an old rule that says you only ask the same flavor to play together. ...unfortunately, with some of the newer ion types, they need to be practically the same service age as well.

Are you saying you just got one (from amazon or other venders) and what you got is dated as being made in 2007? If so, I'd return it since if it's been on their shelf that long, the battery will likely not accept a charge now. If you're saying you've had it since then and wonder how good it is now, that depends on how it's been treated and used. I have a different brand that I've had for 10 years and took it camping several months ago. I used it to power a raft trolling motor where it supplied ~8 amps for over an hour (it's battery is rated at 18 amp hour). I've kept it charged following the instructions of "Recharge after every use and at least once a month", so that's what can happen.

Hi Matthew. I see where you are going with this. I don't see an actual date on the battery itself. This info may be part of a serial number or another code. I am finding that the replacement battery is not holding a full charge the way I think it should. My opinion is that replacing the battery is simply a temporary solution. Every once in a while I get a message that the battery has less than 5-minutes backup left. This is not right! When I am faced with having to replace it again, I would very likely buy the whole assembly new. Hope this helps.

They last about a year. You can buy upgrades for it ( more run time). Batteries aren't covered. They are expected to be replaced.

Like the others said I guess it's in the item specs. To be honest I've never had to replace them or anything. I have two of these and one has been going for a few years. Admittedly they only get used on occasion but the batteries have held up.

It might be a bad battery. The batteries on these things aren't the best. You should be able to pick up a new batery online for $40 or so.

Yes you can use rechargeable batts. they last for a good period of time..I've been using. Rechargeable batts for a year and everything good.

Hi, I have 4 of these, 2 which are 2 years old and I have not had to try to replace the batt yet. Stillstrong. 1 I use for work and keep it plugged into an outlet all day using a usb cable and cell phone charger adapter. I love being to erase any song on the fly without plugging into my computer!
