Lighter battery options 07 WR 450

26 posts in this topic

I have experimented with a couple of versions of lithium ion cell batteries but with the possible overcharge conditions this may not be the safest route.

Has anyone tried the smaller led acid battery YTX5L-BS from the WR 250. It is only 1.25 lb lighter but every bit helps. The CCA is quiet a bit lower. This seams like an easy try for the guys that own both bikes. Let me know what you think.

It's too bad that you got disenchanted with the Lithium ion batteries, as they have several benefits. There are many satisfied customers out there currently using JoeT's TurnTech Li battery. I have been using them successfully since they first became available in both of my KTM's.

+1 :banghead: especially seeing that you can buy and build the battery for half the cost!

I have a TurnTech 2.5, tried to install it in my 09 wr450, too big width wise.

I ended up using it in my KTM450. So far no issues, works fine. There are plenty of guys on the Husky forum using these batt's in 250,450, 510's. Their always looking for weight savings.

I've used Ebatts for 3yrs. First the Nicads now the Lithium. Never an issue with overcharging and my bike gets reved out hard in 3hr races.

If your batteries are overcharging it's the regulator that has a problem not the battery. I have had my 2.5Ah turntech for 1 full year now and it works perfectly. WR Dave

I used the earlier version which didn't have a cover on it. Maybe that is the issue, since I haven't seen the newer ones. Here is my thread on our local clubs forum. WR Dave http://forums.rmdra.com/viewtopic.php?f=3&t=4002

Thanks. It looks like turntech has added a gray plastice case to their battery since you bought yours. Just comparing yours to the pics on the turntech site...

Yeah I had an ebatt ordered but canceled to order the turntech. The reason for the change was that ebatt recommends you don't run a hose on their battery. This is unacceptable since I routinely was my bikes with the seat off and a twin air cover to clean inside the airbox. I really didn't feel like removing the batter every time I want to do a "good" washing. The turntech appears to be well sealed and they make no mention of avoiding water.

It won't fit in with the case. The case tappers and is wider on top than the advertised size. You will need to remover it from the case. I wrapped mine in silicone tape.
