I just bought one for my 2005 CLK500. If I don't charge it then it will be dead in the spring. The trickle charger has been going on and off for about a week. This is the first trickle charger I have used and I think it will be better than when I was using a charger every few weeks. It puts out less than the charger just to maintain the battery. I think it will be ok. I think if you were using a charger on 12Amp then you would be risking damaging the electronics.
I only posted once why did it reply 3 times???
Thanks for the help. I counted 10 replies but they were all yours The forum police need to look into this!!
badali, I don't understand the issue with the replies. Please explain.
Right after I posted there were multiple duplicates of my reply as if I was copy paste and replied again and again. later they disappeared.
Never saw the copies. Must have been some glitch.
Although the electronics in your 98 SL may be different than in my 89 SL, I've never had a problem hooking up a Deltran Battery Tender during winter storage. Actually, I use them on the John Deere, the Harleys, etc. without issue, and everything starts right up each spring.
