Yucel Y2.1-12 12v 2.1ah battery replacement rechargeable AGM.
Replacement Yucel Y2.1-12 battery pack, rechargeable 12v compatible valve regulated sealed lead batteries, 2.1ah non-spillable often used in alarm systems, hoists, emergency lighting.
When you receive your order from us the batteries will be almost fully charged but even so you should still complete a charge before first use, the only time you do not need to do this is if it's going into something with its own always connected power supply, for example a home or commercial alarm system, as this will do the job of charging for you. it shouldn't take long, just until the charger lights indicates its ready. if really in doubt then overnight will be more than enough but it's doubtful you would need to leave it on the charger that long, 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's not always apparent but it will take up to ten charges combined with use in your chosen device before a full capacity charge can be achieved, this is just a normal part of the conditioning process, each time you have used your battery then you should put it back on charge as soon as you can, do not leave it sitting in a semi discharged state for any longer than necessary, you should never deliberately discharge the batteries. we are often asked will this extend the life but no this will only reduce its life span and cost you money in the long run. 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 24hrs.
