I have never had a problem with my Cteck Battery Charger from GM. I have been using it for five years on four different C7's with no problem. What I have problems with are the Battery Tender Jr. I have three of them laying around that quit working that I use on my PU trucks and motorcycles. When they start blinking green real fast I know they are toast. I don't buy them anymore.

Have 7 Schumacher Battery tenders all purchased from Walmart for about $20-$25 each. All have lasted years without any issue.

All our vehicles/bikes not used daily are on them and we've have never had an issue with them not maintaining the battery. Anyone that doesn't have one on a vehicle that's not a daily driver doesn't understand the battery draw due to all the electronics in the vehicles. Get one, use it, prolong your battery life.
