The batteries you receive from us will be almost fully charged, but you will still have to charge them before first use, the only time when this is not the case is when its going in something with its own built in power supply like an alarm system, while you only need to maintain a charge until the charger indicates that its ready, it probably will not take long and it is very important so not a step you should overlook, do not just fit them and roll without this initial charge, it will help to extend the battery life overall
You probably will not notice but it will take up to ten charges and associated use in your device before the batteries are capable of taking a few capacity charge, this is normal, make sure that you charge your new batteries after each and every use, they are capable of many charges but this will reduce if you let run them down in-between, going out of your way to fully discharge the batteries will reduce their life span, so do not do it, if it turns out there are periods where the equipment is not being used on a regular basis then ensure the batteries are fully charged before any period of downtime and then topped up every four weeks but do not leave on the charger for more than 24-hours
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 portable equipment, there is no maintenance required, except of course charging which we have covered on earlier on this page, both VRLA and AGM
We offer the information on this page purely as a guide only, if you carefully check the code on your old battery then you should be ok, many are very similar so it's worth being vigilant, if in doubt look at your old batteries, take note of the dimensions and anything written on the side of them, we have included the dimensions of these batteries so you can double check, as the batteries are made of lead they are recyclable and environmentally friendly, more information about recycling can be found on a link at the foot of this page
