Another vote for the Aldi charger. The latest version is slightly
smaller than the previous one and has better functionality.
Specifically: Greater accuracy of the voltage display and
tighter control of charging voltage. It also starts charging
at the motorcycle charging rate on power-up. The old one always
powered-up in 'standby' mode, which is no good if there is
any interruption to the power supply.

The downside is you have to wait until they have them in stock.

I've a few ctek chargers, pricey but great yokes, especially with the panel mounted sockets wired to the bike.

Ctek are the best I've found. Had optimiser that all eventually gave up, but the ctek ones are still all going strong.

Re: Battery Tender recommendations please

I bought this on amazon about 2 years ago and it works great.

Always hook the girls up when I go on holidays or weather gets too cold just in case.

Re: Battery Tender recommendations please

Cheaper to be had, but it's good quality and charges lithium and lead acid. It has recovered a couple of dead batteries for me, charges 6 or 12v and trickle charges.

Re: Battery Tender recommendations please

Are those Aldi chargers actually battery tenders?

All it says is that that are chargers and trickle chargers, says nothing about leaving them permanently connected while parked up for a few weeks.

Will they actually maintain a battery properly if left connected for a long period of time?

Re: Battery Tender recommendations please

Trickle charge is the maintenance function or battery tender function. In saying that I try not to leave any charger permanently connected, fried/boiled a couple of batteries the way not sure why but stopped leaving charger connected for extended periods. Usually stick the charger on for a day or 2 every couple of weeks.

Optimate. Leave it connected permanently, no issues, been doing it for years. It is a condtioner/tender more so than just a trickle charger that can monitor battery status and auto adjust accordingly.

Sounds like you were on one of those aldi ones...

There's a difference between trickle charger and a battery maintainer. Trickle charger will keep sending small chargers all the time, where the maintainer will let the battery go down and then charge it back up.

It's all about the small print :)

No was a more expensive optimate one, which I still use. Ive also got a lidl battery charger which mentions trickle charge too but the product guide then explains it is microprocessor controlled to monitor battery charge to keep it topped up and conditioned. Probably the website doesnt give full explanation of all features. Looks same as the aldi one too but might not be. Still worth 12.99 as a charger anyway.

+1 for the optimate. Iíve had one for years now and leave it plugged in if Iím not using the bike for more than a week. Never had any problems and itís easy to connect once youíve the lead with the connector attached to your battery

Re: Battery Tender recommendations please

Does anyone know, is it safe to attach one of the dongles that comes with them maintainers direct to the batter of a Canbus system bike? Or should you remove the battery from the bike before connecting the maintainer up to the battery?

Re: Battery Tender recommendations please

It seems I accidentally unplugged the extension lead powering the Optimate charger connected to the FJR1300 some time last year, and when I went to start the bike yesterday, it was almost completely flat, so I reconnected the Optimate charger, but it was having none of it, the battery was goosed... Until I decided to try one of my CTek chargers on the 'Recondition' function, and now it's working perfect.
Saved me €120... So I've just resigned the last of my Optimate chargers and ordered another CTek.
