Worked great for about 18 months then just started erroring anytime I put more than 2 batteries on a side. Didn't matter if they were the same size or mixed (AA & AAA). Errors out and all 4 charging indicators show full charge even on a completely dead battery.Update: Even though it was outside the support period, the company replaced the charger free of charge and the new charger is working great. What great customer support.The EBL batteries are great and very powerful for the sizes I have (AAA and AA). They last quite a long time in my mouse and other devices and charge quickly in the new charger.
