AA Batteries, bulk buy ?

TheBlaaMan

Any interest in a bulk buy of Hi Capacity AA rechargeables? Thinking of 2850 or 2900mAh NiMH. They would work out at less than €10 for 4, including postage to your door, perhaps a good bit less, maybe as little as €8 50 if your not a brand whore....

Have you tried them before? Most of my noname-lidl high capacity rechargeables last for about 6 month and then they get fast degraded.

Maplins do 100 1500mAh AAs for 19 Euro.

Yep, you can get lots up to about 2200mAh for peanuts, but really high capacity for lights etc (need to be about 2750mAh) are not so easily available. As to brand..........I'm still doing my research

I've a set of these that have been used and charged daily for two winters and going strong. Good price too.

Check out hybrid rechargeable batteries - they hold their charge much longer when not being used - ideal when you carry a backup set.
The 'Which' consumer group in the UK tested high capacity rechargeable batteries and their top 3 are:
1. Energizer Accu recharge 2650 mAh
2. Maplin Extra-High Capacity N05BW 2500 mAh
3. Energizer Accu recharge 2450 mAh

I've switched over to Hybrid batteries last year (Uniross Hybrio) and found them much better than the cheap Aldi/Lidl rechargeables.

Until quite recently, 7dayshop offered their own branded NiMh AA's in capacities up to 2900mAh. For some reason, they are now offering only 2100 & 2500mAh. I've been using their batteries for about 5 years for all sorts of stuff and there have been very few failures or problems.

They are currently offering 20 x AA, 2500mAh for £17.99 (approx €21), which is pretty good value I think. P&P to Ireland is £5.95. Unless you specifically need that extra little bit of run time that a 2900mAh battery would give, this deal may be just the job.

It's also worth noting that nominal capacities are just that. Independent tests show that very few batteries deliver 100% of the stated capacity and there are considerable variations among products from different manufactures. This table is a little out of date now but illustrates the point. The Accupower 2900mAh AA is outperformed by 7 other batteries, all with lower nominal capacities, including 3 with only 2500mAh capacity.

Personally, I wouldn't bother paying a premium for 2900mAh AA's unless I could verifiy that I was really getting the extra performance paid for.

Thanks MP. but even at 2650mAh, these are still below that recommended for my light (Hope Vision 1). This light requires batteries with a minimum power of 2850 mAh.

All other things being equal, the only noticeable difference in performance between 2650mAh and 2850 mAh batteries will be a slightly extended run time for the latter, assuming you actually get the additional capacity you are paying for! So unless you are finding that your lights are failing at a paritcularly inconvenient time, whereby a little extra burn time would make a big difference (e.g. by getting you home safely), the disadvantage of using a slightly lower capacity cell ought to be negligible.

I have a Hope Vision 1 as well and find 2300mAh and 2500mAh batteries are fine (TBH I didn't even know about recommended batteries ). I just bought the light, threw in some batteries and went for a ride.

They last about 3 hours in total but at different settings i.e. when I'm on lit roads I use the lowest setting and when on unlit roads I use setting 2 or 3. HTH.

Thanks guys, good stuff. TBH, I've not taken delivery of the light - I wanted to buy the batteries in advance.
Those 7dayshop AAs may be a good side bet.
