The batteries will be delivered with a very good charge in them, but even so you should still charge before using for the first time, if the battery is being fitted in something like an household or commercial alarm system then you can miss this step as it will do this for you, you only need to charge until its ready, it probably will not take long and it is very important so not a step you should overlook, you may well just want to fit them and use the equipment, but do not miss this first step if needed, it's worth waiting until the first charge has completed and it may well contribute to over life span

It will probably not even be apparent but it will take up to ten charges and associated use in your device before the battery is conditioned and capable of receiving a full capacity charge, this is quite normal, after you have used your batteries you should get a charge back into it as soon as you are able, do not leave it sitting around in a partially discharged state for any longer than absolutely necessary, do not try to fully discharge the batteries, it will not rejuvenate them, it will reduce the lifespan and cost you money in the long run, if not using the batteries you should remember to recharge every four weeks and never put them away discharged, even partially, do not leave on the charger for more than 24-hours at a time

These batteries are deep cycle capable, which is essential in this type of application, the VRLA and AGM cells will not leak and not-hazardous so suitable for travelling, there is not maintenance required, except of course charging which we have covered on this page, both VRLA and AGM

 

Ensure that you order the right battery by carefully checking the information, a lot of them are very similar so it can be easy to make a mistake, if in doubt check the old battery, the dimensions and anything written on the side of them, we have included the physical size so you can double check, These 12-volt 2.1-amp hour batteries are recyclable, the main component is lead which can easily be recycled, more information on this can be found at the bottom on this page on our recycling link
