Sorry guys but i dont know if the deal is nationvide, but still worth a post.
Just went in my local ASDA (Leeds Morley) and found these great batteries from SANYO reduced from £9.97 to £4.99!!! They are £6.75 in Amazon.
SANYO Eneloop are the best rechargable batteries i have ever used and as a professional photographer i do know about batteries.
These are the new improved type batteries that can be recharged up to 1500!!! times without any memory effect.
Some technical data:
-Can be used straight after purchase
-Long shelf life with no loss of energy
-Rechargeable up to 1500 times
-Retains 75% of its capacity for 3 years
-Operating temperature as low as -20°C
-2000 mAh (1900 mAh min.)
UPDATE: I have been to few more ASDA stores and some of them are selling the old type Eneloops so dont fall for that. Make sure it says 1500 recharges on the packaging. Saying that i think that even the old ones are good for this price.
