so what's the score with these Tanya people regarding returns they reckon are not faulty, are they making you pay for carriage both ways?
This is their message to me this morning after I emailed them the RAC evidence (just noticed it states 50% are returned that just need charging but they quoted higher on the phone)...
Thank you for your enquiry.
No problem. Please pack the product up securely and let us know a suitable day for collection. We will test the product and if found to be faulty will despatch a replacement.
Please note that all returned batteries must be packaged to a minimum standard to avoid damage and leakage. To achieve this level please follow these steps:
1. Package the battery inside a cardboard box.
2. Ensure the battery itself is plugged as received and wrapped inside a plastic bag (inside the box).
***********************************
PLEASE NOTE: Your battery is wet and MUST BE PLUGGED for transit, as it could spill if tipped on its side. We can post you some plugs if you do not have the original ones. Please respond to this message if you need these and we will send first class.
***********************************
3. Please ensure there is at least 1 inch of packaging around the battery inside the box to help protect against courier damage.
4. Seal the box and write 'This way Up' so it can be clearly seen by the courier.
5. Please be aware that any damage incurred during transit due to poor packaging will render any claim invalid.
As a side note, please perform all necessary checks to ensure that the product itself is definitely faulty (and nothing else could be at fault) before giving a date for pickup because if not faulty you will be responsible for the pickup and return carriage charges.
I suspect that the battery is not faulty, but has been discharged. The lowest voltage a battery can get to by itself is 10.5v, your battery is around 7v, it is impossible for a battery to get to this voltage without being discharged by something on the car.
Bear in mind that 50% of batteries returned to us for testing are just flat and need recharging!
