Review: A great product which does wonders for battery longevity. - 3rd optimate purchased for family motorcycle battery maintenance due to being a great product ,which in this purchase recovered the battery back to full health after 24hr charge. Would highly recommend to anyone ,purchased at a great price with very quick delivery.
Review: Buy before you replace your battery! - I bought a replacement battery for my bike, but like an idiot I didn't even think about how I was going to charge it! The old one barely held a charge for 3 days and in winter when it needed a bit of extra cranking power it just died all the time. After reading lots of reviews and wanting to be kind to my new battery I bought this Optimate. I quickly flicked through the manual and noticed the recovery option so thought I would give it a go. As soon as I plugged it in the Optimate indicated that it was in recovery mode (automatically) so I left it overnight. Next day I came to it and the green LED for fully charged was lit! Needless to say I left the old battery in and it's working like a new one (it's 9 years old!). Unlike some others, I've had no trouble seeing what it's doing by a quick glance of the LEDs. Once you've looked at the chart in the manual a couple of times you will know what's going on in the future. The alligator clips to the battery are perfect. Very high quality, easy to get on and they stay in place. It's also nice to see another quality cable included that you can wire permanently to the battery so charging is just a case of plugging in! This is quite simply a magic box that will bring your battery back from the dead!

## Questions & Answers

**Q: And does it come with the correct plug connection for a bmw 800 gs? many thanks**
A: HI, this comes with a direct to battery lead which is a good idea.  It's also canbus compatible should you wish to connect via the BMW power socket (additional part needed)  feel free to call me on 01443 742421 if you'd like to discuss in person.Thanks,mike.

**Q: does this charge a sealed battery and a dry one very confusing**
A: Hello Janice running it on a sealed for life battery YTX20L-BS. Not sure what you mean by dry unless you are talking about a car battery. Other than that the literature states it can do all of them.

**Q: is this suitable for first charge on a yuasa ytx14ahl-bs, battery label states 1.2 amps for 5-10hrs, if so can i use it to maintain the battery as wel**
A: Hello Yes this will be suitable for your battery and the Optimate 4 will be compatible with many other battery types for future usage.    Kind regards    Derek

**Q: Is the the dual can version.  does it have the new sae connectors or the ones in the picture?**
A: Hi, all stock is the new SAE version, I'll try to change the pic to match:)  Feel free to call me on 01443 742421 if you have any further questions.Regards,Mike

### ⭐⭐⭐⭐⭐ Very very good
*by M***N on 29 March 2012*

The optimate range have always been pretty good items and the Mk4 is a very good, compact intelligent battery charger. I ordered mine as my battery was strugling in the cold weather and although the charger is showing that the battery is good it has no depth of charge, I think in all fairness to the charger the cold has goosed the battery completely and especially in the mornings I have been resorting to bumping the bike, however for the last 2 nights I have left the charger connected overnight and while the bike is struggling a little on start when cold it is allowing me to start it on the button. I reckon I ran it too long with a dodgy battery before buying the charger. I do rate the Optimate highly and the extra connector to allow the charger flying lead to be connected up to the battery and left under the seat is quite frankly a godsend, as otherwise I have to remove half the luggage racks and then a side panel to get at the battery (Yammy Diversion XJ900) so that is a great idea. Have new battery on order and I think the Optimate will keep me rolling till it arrives. Fingers crossed anyway, the charger is also sealed so its waterproof and compact enough to be connected up, put under the seat and the seat replaced with no fuss at all. I would recomend this product to anyone looking for a high spec battery charger that will also work with Gel batteries. UPDATE and admission of fecklessness! I ordered and received a new battery, thought that I'd just check it with the optimax, it was unsurprisingly fine, but I noticed that when I connected the charger it did things I hadn't seen when I plugged it in to the bike, so back to the bike, double checked the old Optimax battery lead I had fitted and discovered that at some point the fuse in the extension had gone (Muppet!) so switched fuses and it is now going through the full test and charge cycle I might not have a goosed battery after all, Yay, but I may have bought a spare I don't need, Boo. Ah well at least the Optimax is working fine :)
