If you use a backup power supply that utilizes RBC11 batteries, it’s a good idea to replace them once a year.
As with any battery, knowing how long it will last is an impossible guess; it is said however, that an RBC battery will last approx a year. If you are looking for an answer on how long should you leave it before you change your battery, then you should err on the side of safety and do not leave it any longer than two years. 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.
Replacing your emergency flashlight’s batteries is comparable to this practice. Rather than wait and find out the next time ligtening strikes a generator that the batteries inside your flashlight do not work, check them out beforehand to make sure they do work.
Before buying your new RBC11 battery, make sure to take a look at your current battery and write down the specifications. Hardware manufacturers have a tendancy to change their specifications without notice; beware of this because the manufacturers website may list one size and your RBC11 may be 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. When this occurs, avoiding paying extra postage and handling charges can be difficult as it’s usally down to the buyer to ship the mismatched battery back to the retailer.
Safe battery disposal is extremely important so ensure you purchase from retailers who offer safe battery disposal. Due to the various leads and acids you’re not allowed to actually just simply drop your old battery in the trash. Some manufacturers offer a disposal plan when you buy your new ones, this not only saves you looking through the phonebook for a battery disposal facility but means you can use the same box your new batteries arrived in to ship your old one back.
