Apc Rbc18 Vervanging Accu Patroon 18, 36Mmx302Mmx102Mm, Zwart

A few years ago, I didn't think much could be said about replacement batteries for an APC Uninterruptible Power Supply (UPS) and this is still true, however there are a few things that make a genuine APC replacement battery cartridge a better deal, even though they cost more.1. These batteries are already paired and have the appropriate leads attached, so replacement is very quick and easy. I don't have to tape them together or spend time transferring the leads from the old batteries.2. These batteries have the correct terminal tab size for attaching leads. Many batteries come with narrow tabs.3. These batteries have much more lead than all of the others I have used.Why do items 2 and 3 matter? Well, attaching the leads with a proper, mechanically tight connection makes for a low resistance electrical connection which is critical for UPS function. And, weight matters in batteries. The amount of lead determines battery life, both how long the batteries will provide power in a power outage and how many times they will recharge and do it again.Yes, these are more expensive than all of the others, and no, they don't tell you how many Ampere-Hours they produce, so how does one compare batteries?I support a pretty large number of APC UPS units tangentially to my real work. I have tried all of the other brands I've found on the Internet and locally. You can take my word for it, or you can compare the weight of the old APC battery pack you are replacing to the new pack of any brand. There has always been a measurable difference, with the APC batteries being a pound or more heavier. This has translated, in every test I made, to a far longer life for the APC-brand batteries--for example as low as 6 months for cheaper batteries compared to 2 to 3 years for the APC-brand batteries.The most recent test I performed, with a national-brand battery pair, available locally, lasted one week and failed in the first 5-minute outage. This was probably due to a defective battery. However, I have never had an APC battery do this.Enough said.

Generic brand of battery from Ritar, not genuine APC, started failing after 8-9 months (with UPS beeping intermittently).

Product is easy to install and works as it should.

Everything worked as it should. I read some reviews that it would be difficult to fit it into the compartment, but everything was very easy.
