Formal complaint to Manbat

I’ve had enough. They’re blatantly ignoring me so I’ve sent a formal ┬ácomplaint into Manbat’s head office. Here’s the email:

Dear Sir

In January of this year I made contact with a chap called Bryan from
Adverc. We discussed my battery needs after me giving him detailed
information as to my usage in a motorhome, and we finally decided that
the Numax XV24MF would suit my needs best.
I ordered them and they were delivered in February from Manbat’s
Bristol depot, I had not known Brian was a reseller but that’s a minor
point.

The charging regime I had been told to use by the Bristol branch was a
cycle for Sealed Lead Acid batteries, as they are.
By May they were significantly reduced in performance. I ended up at the
Chesterfield branch where Steve Davies took the batteries in to test.
After one week the test revealed that all batteries were down in
capacity by at least 25%, however one was as low as 64% efficiency,
clearly there was a problem.
Mr Davies after having seen my robust and careful planned setup,
(wiring, charger etc) deduced that the problem with the batteries was
probably to do with the incorrect charging regime that Bristol had given
me, however he felt that they may ‘recover’ over time.
Mr Davies pointed out that they should be charged as Open Lead Acid
batteries, even though they aren’t.
Tayna who also sell the same battery insisted that they were charged as
SLA’s, rather than OLA’s however as Mr Davies is branch manager at
Chesterfield I changed the charging regime to suit his recommendation.

There was no appreciable difference in the batteries’ performance,
however they continued degrading until I finally contacted Mr Davies
again to point out that although the maximum draw per day was about 45
amps (9 hours at 5 amps), 3 of the 86 ahr batteries in parallel were
only lasting 9 hours (45 amps in total). I should have very easily
expected 120 ahrs from that setup.
I am now using a different laptop and my hourly draw is about 3 to 3.5
amps max, yet 3 x 86ahr of the batteries in parallel still only last a
cumulative 12 hours.

Mr Davies has been very helpful and patient, but when I contacted him to
let him know that the batteries were getting worse, he replied that he
did not now know what else could be done. My reply was that clearly they
need to be replaced or me refunded. I didn’t hear back again from him
for over a month, so I emailed again and was told now that he would
contact Brian from Adverc, and ask Brian for all of the details of me
that are on file. I’m not certain what that means, but that was over 2
weeks ago now and my emails and telephone calls remain unanswered.

This is obviously costing me a lot of money in having to run the
generator to charge the batteries every night, rather than once a week,
and is unsustainable, I simply do not have this amount of money to spend.

I certainly have no specific complaint about Mr Davies or Adverc, but
the time delay now is several months and nothing seems to be happening,
and I really need a resolution to this problem.
I am happy to supply extra information regarding my setup as and if you
may require it.

I look forward to your reply.

Regards

Gary Finnigan
