was wondering if anyone uses this battery for their backpack as i bought one today and want to make sure it is correct before i connect it up-thanks
-
As long as it fits into your backpack Darren, it will be fine.

thanks jeff,one more thing,silly question but my old battery is stuck on with some type of double sided tape,is the battery ok without the tape as it will be moving about alot?

I think its glue they used to stick them down with ::)
If you feel its going to rattle around alot then get a large elastic band and wrap it around the battery and the platform its on, then it will be fine.

nice one,ill get one tomorrow-looking forward to doing twice as much work.

Good luck, you'll do just fine with it. ;)

Hi Darren and Jeff,
You don't need anything to fasten the battery to the casing. Mine aren't and do fine.

I also think that ALL Sealed Lead Acid 12 volt 7.5 ah Batteries are the same size?
Isn't' the physical size of the cells something to do with the power in the battery?

Hi Dave
Your right, if the battery is the same size then no you don't need anything to hold it in place, Mine just sits inside, the glue gave up months ago ;D

Sorry Dave I never read that bit ::)
12V 7.2 Ah at 20HR Rate
Length 5.95 in.
Width 2.56 in.
Height 3.71 in.
F2 Terminals (1/4" wide)
The 8.2 Ah has the same dimensions as the above.
A battery is simply a number of cells connected together with a given voltage and capacity. The more cells the higher the voltage, the larger the plates the higher the capacity (in general).
Purely for convenience, batteries are made in 12 volt blocks with 6 cells but are also available in 6 volt, 4 volt and even 2 volt, single cell blocks.
Batteries can be connected in series to achieve whatever voltage is required (add the number of 2 volt cells) and in parallel to achieve the capacity required (add the capacities of each parallel battery or string of batteries) For larger systems, a number of series connected strings maybe connected in parallel with each other. This achieves both a higher voltage and capacity. phew! ;D
Under normal operating conditions, four or five years of dependable service life can be expected in stand-by applications, or between 200 and 1000 charge/discharge cycles depending on the average depth of discharge.
