If you use a backup power supply that utilizes RBC11 batteries, it’s a good idea to replace them once a year.

Knowing the exact lifespan of your battery is difficult, but an RBC battery will usually last about a year. You should err on the side of safety when you are relying on a battery to provide you with emergency power backup; so the truth is between one and two years is a safe estimate. Most battery retailers and manufacturers offer a one year warranty simply because one year is the maximum amount of time that you can safely rely on an RBC11 battery.

Your emergency flashlight’s batteries need replacing on a regular basis and this is comparable. The batteries inside the flashlight might still be in fine condition, but they might not, and it’s better to know that they are rather than wait and find out the next time lightning strikes a generator.

Before buying your new RBC11 battery, make sure to take a look at your current battery and write down the specifications. Purchasing the right size RBC11 can be more complicated than you think as hardware manufacturers often change the specifications without notice; their websites list one size and shape when in reality they’re actually a different size entirely. RBC11 battery retailers have stated that one of the most common complaints registered with them is, the battery does not fit. Ordering the right battery in the first place is really important as when this occurs, the onus of sending the incorrectly size battery back is usually down to the buyer meaning a costly event which could have been avoided.

You should also be on the lookout for retailers who offer safe battery disposal. Dropping your old battery in the bin isn’t actually allowed due to the various leads and acids they contain. When you are looking to replace your battery, check out the company’s website to see if they offer a safe disposal plan. Most of them will let you use the same box your new battery arrived in to send the old one back.
