BatteryTender vs. Optimate - charger opinions?
Currently I run a BatteryTender to maintain my battery on the LT. It works OK but there have been times that I don't think it is indicating the right charge state. Example is one that I know I ran the battery down when doing maintenance. The GS-911 said it was at 8.7v. I threw on the charger and the BatteryTender started to immediately flash the green light which means it is at least 80% charged. Then it showed fully charged within 10 minutes. I unplugged the Tender for a few minutes and plugged it back in and it started charging again.
The battery is about a year old and normally I wouldn't even let it get down as low as I just did. I wasn't paying attention to how long I had the ignition on without running the bike. The BatteryTender is about 6 years old.
Don't know if I buy into the desulfating feature on the Optimate because as far as I know, that takes quite a bit of voltage and time to truly desulfate, but I thought I would see what others who have used them think.
Let me know your opinions.
