BATTERY WEIGHTS.

Hi Guys

Just doing some work on my tiger and decided to change the batteries, as I am still on the original 17 ah. I have just acquired some 32 ah and 36 ah, 76ah batteries, but the weight is 10.5kgs each compared 6.5 kgs on the old 17 ah.

not got around to the 76,s yet

.

Has anyone else got these heavy batteries installed? and how is the suspension handling it?

Thanks

Richie

Richie,

Vince fitted larger batteries to his Tiger, but I am not sure of the amp/hour rating or weight. His tank seemed to go well though and not suffer from any difficulties with the suspension. This said I have 22 A/hr batteries, which I believe are the same size as you 17 A/hr batteries and my suspension is pretty low at the rear now, so I would expect some settling with heavier batteries.

Vincent fitted two large square 24 amp batteries originally, but found that they did not have the duration, so he switched to the 22 amp that we all use.

Hello Richie , batteries to the uninitiated, can be a bit of a nightmare , and also the charging of them .
There are some sealed lead acid ( gell cells) that will give a deep disharge , and a rapid charge . I had them in my Tiger and i could if needed ,charge them in under the hour . That being said they were not cheap , i seem to remember them being around Â£120 each They are used by the military and as standby batteries. They are usually red in colour.

. Still my thoughts are , that the batteries are the heart of the tank and should be the best you can afford .
There has been several threads on batteries on here , and on the other site

ps , not forgotten about the charger , its still here

Hi Richie ,
# ive not tried 32ah, im useing 2x 27 ah in the j/p. I seem to remember that the 32ah were physically to high for what i wanted.

Take care not only about the weight but the bulk especially if your tank has reinforcing beams under the deck, or a number of option packs (smoke system, etc.) that take up space.

Hi Ritchie

Just to add some more info for you. I have 28 amp hr. batteries in my early Tiger. These are a deep discharge type as found in disabled persons vehicles. They weigh 18. 6 Kg each and are recharged overnight but give me a running time of about 1hr and 50 min. non stop. The Tiger has not sagged at the rear as when I fitted them I moved the original and second battery plates as far forward as I could and reset all the suspension arms to 37 degrees. This compensated nicely for the Tiger to sit at scale height and to date, almost one and a half years later, the Tiger is correct in ground clearance. I just checked it again before writing to you to make sure. They are, in size, 180mm long X 170mm wide and 130mm high. I will be sticking these into my Jagdpanther as well as I am very happy with their performance. Hope this helps you a bit more.

Regards

Rick Jensen
