How to choose a charger:

A slow 2a charger is generally fine for any battery. If you are not sure or want to keep costs down, get the 2a charger. It charges at 2 amps. Divide your Ah rating of the battery by 2 (a) and that is how long it will take to charge your battery from 0% to 100% roughly. 

*** we never recommend running your battery to 0%. You run the risk of it not working properly if you do it enough. 

Batteries prefer to stay between 30-80% state of charge (Soc) so charging it to 80% is best for a battery. In fact if you keep your battery between 30-80% for most of its life, you can essentially double the life of your battery!
