This is my first post........ woohoo.
I have a 1996 Defender 90 CSW 300Tdi. I have owned this vehicle for just over 3 years. It has always seemed to have a slow battery drain when the vehicle is parked and unused: it's OK for 3 weeks, or so, but then the battery becomes too drained to crank the engine over. This may just be background and not relevant to the main point.
Last week I charged it overnight, but a couple of days later it struggled to crank enough to start. After driving ~40 miles a couple of days ago, It struggled to start again today (but did). Temperatures have been hovering around zero +/- 5C here this past week. I drove about 7-8 miles and measured the battery voltage (engine off) about an hour later. Battery voltage was 12.32 volts. Too low methinks?
The battery is a Varta 110Ah 850A EN which was in the vehicle when I bought it (I have a receipt in the part-service record suggesting a new battery was fitted in January 2009). I have found the manufacture date (thank you YouTube) on the -ve terminal post - 10 08 (10th week 2008!). So, I assume that this is the one referred to on the receipt (a simple garage receipt - no manuf/model details). Whilst I'm impressed it's got this far, I think it is time for a replacement. I'm considering:
- VARTA I1 Silver Dynamic 12V 110Ah 920A car battery 610 402 092
- Bosch car battery S5015 12V 110Ah 920A/EN Type 020
Both are around £130-£140, it seems (from Battery Group)
Does anyone have any advice or comments. Anything constructive is welcomed.
Thanks
