Charging Batteries

Do not leave batteries unattended whilst charging and take off charge when they have completed charging.

When charging the batteries, we recommend charging them between 1-4 hours.
When they are charging the light/s will flash and once it is fully charged, the light/s will turn a solid red or green.

Also once you start to hear the battery getting flat, please recharge it as running it flat can damage the cells.

 Soaking & Storage of Gels

When soaking the gels, they need to be soaked fully submerged in water from the tap for a minimum of 5-6 hours.

Once they have fully grown you can leave them in the water and keep them in or out of the refrigerator.

When you are ready to use them just drain of any excess water with a strainer before you feed them into the mag but do not dry them as they need to be lubricated to work properly.

You can store gel balls in a bucket of water with a lid for up to 3 months before they start to go super soft. We recommend if you do this to change the water every couple of weeks.

DISCLAIMER
Do not upgrade any part of your toy gel blaster as this will void the warranty. Upgrades refer to pulling any of the blaster apart or opening it up, changing springs or upgrading the battery from 7.4v to an 11.v battery.
