Battery and Tenders

[2Gunns]

I'm now on my 3rd battery for 2010 RT-S, seems 2+ is about as good as it's going to get, but what does suprize me is the short term... if I happen to forget to put it on the tender it's dead in a weeks time, a quick overnight charge brings it back to life, but is this normal? I keep bringing this to the attention of my service tech at dealership and all he says is "there's a lot of stuff going on in the background pulling power... keep it on a tender"

If it's not running, plug it in. Besides the constant draw on the battery. A battery will start to sulfate if not on a trickle charger. So, plug it in. Tom

I have used Deltran Battery Tenders exclusively for many years. I used them on a car and a motorcycle while we were in Florida for 5 months of winter. Never had a failure to start in the spring.

6 years out of my OEM battery in my 2010 RTSE5, never kept it on a battery maintainer, However I only got 13 months out of the replacement but that was in HOT SW Florida. I still do not put it on a maintainer but it is driven daily since it is the only vehicle I have other than a motor home in storage.

If you killed it once you probably damaged it and thus it will never be as good and won't last long. If you have a tender,,, use it all the time. A BATTERY TENDER is not a TRICKEL CHARGER!

If you use it every day,,, keeping it on a tender is certainly not needed.

Can't let this go by without a couple of comments.

IF.....the machine is ridden at least every few days for a decent amount of miles (10+), there is really no need for an external charger.

IF.....the machine has an AGM battery, which I believe all the newer ones do, sulfation will NOT be a problem unless it is allowed to go stone cold dead.
AGMs don't suffer from the condition like wet-cell types do.

Then there is the charger: Anything marked as a "trickle charger" is NOT good to leave connected all the time. It could do more harm than good.
You need a small tender-type fully automatic charger.

I was told to only put it on the charger if it not going to be driven for an extended period of time. Mine sat for a week without turning it on and it fired right up. I think you may have another issue.
