smart battery charger recommendation for AA, AAA, C, D and 9V
« on: November 23, 2019, 01:52:22 pm »
Current Ansmann Energy 8 (non-smart) charger just failed after being knocked on the floor. Power input sheared off internally and it's not easily fixable and mains voltage parts are no longer secured properly. New charger required.

Requirements:-
* Mains powered
* Can charge at least 4 batteries (AAA/AA/C/D) at a time a well as a couple of 9V batteries
* Smart functionality (i.e. ability to charge/discharge/test/refresh batteries and give details of individual batteries) for the AA/AAA batteries (and ideally for the C/D/9V but not absolutely necessary)
* Has to be safe to leave the batteries in the charger for weeks on end

Doesn't have to have the smart functionality for the 9V batteries (although it would be nice) as they generally get installed singly and so individual capacity is less of a problem. So the solution might just be a smart charger for the AA/AAA batteries (like the Technoline BL700N) and then a dumb(er) charger, I think I have one somewhere, for the D/9V batteries but it has to be one that I can just leave the batteries in (like my old Ansmann Energy 8).

Any ideas?

I have, none of them cover the requirement for D and 9V cells, hence the new thread.

Not helped by the fact that many people just post links to Amazon or eBay with no description of the brand or model number, and those amazon/eBay links are long dead.

Youshiko YC6000 would cover everything except 9V.

Was thinking about one myself as my Technoline BL700 has a few faults with it now (only 3 working channels, missing LCD segments, and charge function only working). It also does 18650 batteries etc which are common now.

Manufacturers website - Youshiko YC6000

Cheaper from Amazon

Amazon - Youshiko YC6000

It has intelligent function so will sense when a battery is fully charged and reduce to trickle charge but whether you'd want to leave any battery charger unattended for weeks is another matter.

Interesting one above, but I wanted 9V charging too (smoke detectors and a small portable radio) so I've taken a cheap punt on this:-

https://www.ebay.co.uk/itm/LCD-Smart-Battery-Charger-for-Ni-MH-AA-AAA-9V-Li-ion-18650-26650-20700-LiFePO4/163918043469

I can't provide any reliable info about it as there's no discernible branding and seem to be offered by a whole load of random eBay sellers, so this does not fill me with confidence.

[EDIT] TOOGOO-BTY-V407 seems to be one of the brands/models. Googling for BTY-V407 gives a variety of different brand names that are rebadgeing this.

It certainly won't be left on unattended, I may even open it up to check on its build quality, HV/LV separation, etc.

Would still prefer recommendations for trustworthy smart chargers that can do 9V batteries too. Here's the only one I've found so far that fits the criteria (and from a well known manufacturer): https://www.ansmann.de/en/battery-chargers/powerline-5-pro but it only fits one 9V battery at a time (available for ~£40 if you search around).
