AA battery/charger recommendations please..

sj (Elite) posted this on Thursday, 27th November 2014, 16:44

I've never really used rechargeables before but am looking to get some - and a decent charger too.  Will be using 4 in a handset for an RC car that I'm looking to buy for 'the boy' for Christmas (and would welcome advice there too)..
Anyone recommend some batteries and charger?  8 AA batteries I would think.
The car I'm looking at getting is this.  The battery options (and connections!!) available for RC's are rather daunting.. Not going to go down the LiPo route.

useful info in this thread
http://www.myreviewer.com/Forums/General/t879339/Battery-torch-and-charger-reviews/page1

looking at hotukdeals, people often rave about Sanyo eneloop, I think as always you get what you pay for. I've got some from poundland which are ok in a remote, but die very quickly in a torch

Thanks from: sj

Cheers, seems too geeky for me. :)
The batteryshowdown site seems for 'normal' batteries?

I recently got this...

Which is worth about the price of the batteries alone. The charger's a slow one, it will take about 10 hours to recharge two of them, although I haven't opened the pack yet. The batteries are supposed to be great though.

Got it to replace a Uniross XPress piece of crap. Can charge the same battery in about three hours, but will tell you it's charged after fifteen minutes, so you have to switch it on and off again each time it does, until you've figured that the battery actually is charged. Of course doing that cooks the battery so 1000 lifecycles turns into abou 150 before the battery's useless.

Everything I've read suggests that the slower a charger works, the better for the battery.

As others have said, the slower you charge the battery the better, the more capacity it will be charged to and the more charge cycles you will get out of it.

Eneloop or Hybrios (same technology, different brands), whichever is cheaper! Any battery sold as coming pre-charged uses the same tech.

Avoid fast chargers, and get an intelligent charger that switches to a trickle top-up charge when the battery is (nearly) full. Also get one that charges batteries individually, and not in pairs or quads.

I have a great Maha charger, but it was about £50 I think and probably a bit OTT for your needs. ;)

Vapextech have a eBay outlet, might be worth looking first, but that seems a very good price for that unit. Never had those batteries so can't comment of them.

Cheers.  I know what you mean about the batteries but they seem to get good reviews.  I did look for eneloop too - but the ones above also mention precharged which Rob mentioned.

They'll be the same tech as eneloop. I last paid £5.39 for 4xAA 2100mAh Hybrios if that's any price guide.

The only thing that concerns me about the charger is it's a fast charger, and I couldn't see how long it says it takes to charge, or at what current it charges them at.

The faster you charge batteries, the lower capacity they reach when charged, and the quicker they wear out. I think as a general rule you want to charge a battery at half its mAh rating, so for a 2000mAh battery you want to be charging it at 1000mA.
